In my experience with some conservatives, it seems that they believe global warming is happening but they are skeptical of how effective left-leaning politicians can be in combating climate change. Therefore it is not worth conceding political turf on other issues if they will see little change in the rate of global warming.
Interesting once you start to take into account other countries contributions to global warming. The United States is relatively low among developed economies when it comes to emissions per GDP : https://en.wikipedia.org/wiki/List_of_countries_by_ratio_of_... .
I am really not impressed by any sides efforts to combat global warming.
Of course this will be met by criticism from HN, but I would love to see more discussion beyond conservatives are anti-science radicals who want to kill the earth.
The messaging coming from Republican politicians is either that climate change is not happening, or that it is a natural cycle and nothing to do with humans. Both of these hypothesis are objectively false.
Setting that aside, emissions per GDP is an interesting and useful statistic, but it doesn't paint a complete picture. If you were to entirely eliminate the top three highest emissions per GDP countries from your list, you will have done nothing to combat climate change. If you sort that list by total emissions, the US ranks #2 a short distance behind China. China is actually fifth from the very bottom of that list.
It's a complex situation and will have an impact on the global economy no matter what. We can decide to do something now and take short-term losses to prevent massive devastation in the long term from doing nothing.
> I am really not impressed by any sides efforts to combat global warming.
Hmm. What would impress you? I honestly think climate change is the most important issue in the world right now, and I would love to know what we can do to get you on our side.
> The messaging coming from Republican politicians is either that climate change is not happening, or that it is a natural cycle and nothing to do with humans. Both of these hypothesis are objectively false.
Climate change is a shibboleth and people largely appear to recognize it as such. For example, in Ware County, GA (to pick somewhere at random), 70% of folks voted for Trump but 2/3 answered "yes" to "global warming is happening."
> I honestly think climate change is the most important issue in the world right now, and I would love to know what we can do to get you on our side.
Supporting diplomatic efforts to combat climate change are virtue signaling. I'm an environmentalist and I agree that climate change is probably an impending disaster. But diplomats aren't going to fix it. The Kyoto protocol, for example, accomplished almost nothing: http://www.circularecology.com/news/the-kyoto-protocol-clima.... The only thing that can save us (if we can be saved) is technological breakthrough, and the prospects of that happening won't change based on U.S. participation in international climate change protocols.
The phrase "virtue signaling" is so useless. As if any action that does not have clear and immediate results is just posturing and pandering.
I think change absolutely has to come from governments and thus diplomats. Are corporations going to cooperate at a global scale to fix this with no regard for short term profits? Corporations like Exxon knew about climate change 40 years ago. Personally I think we should be litigating against a corporation that would hide something of global importance like that.
Where is the money to research these technical solutions going to come from? The article you linked showed that there were improvements among the signatories even though without the fall of the USSR it would have been 2.7% vs. 4.7%. Still it was something vs. just saying "this problem is too big to solve, let's hope some smart scientist finds a fix before we all die". Had China and the US been adhering to the Kyoto protocol undoubtedly the impact would have been much greater.
> The article you linked showed that there were improvements among the signatories even though without the fall of the USSR it would have been 2.7% vs. 4.7%.
That's rearranging deck chairs on the titanic. And acting as if that's an important thing to spend political capital on is precisely "posturing and pandering."
Still not seeing your point. The goal is x. We achieve x/2. We still achieved something. We proved we can actually make an international agreement with long term goals and short term sacrifice and make improvements. I don't really blame politicians for taking further credit and trying to spin their success as even more impressive. Do you think the Paris agreement (https://en.wikipedia.org/wiki/Paris_Agreement) would ever have happened if not for that initial (however small) success? Reading the aims it seems on the surface to provide reasonable goals that balance growth and fairness with trying to prevent climate change.
The problem I have with pointing to international frameworks as failures because of their less than optimal results is the alternative.
How could we fix the climate more effectively? Elect a world dictator / threaten other countries with nuclear annihilation unless they cut their emmissions.
I agree with you about "virtue signaling". I don't agree with Rayiner about this stuff, but in a good, sort of bracing way --- until I get to the line where he says that everyone trying to do something politically about climate change is doing so in bad faith.
At some point there's a threshold beyond which alternative enegry sources become more profitable than fossil fuels, and at that point zillions of dollars will be spent on R&D. We're getting there, albeit perhaps a little more slowly than environmentalists would prefer.
One way to ensure that doesn't happen is to put a tax on carbon emissions. Governments then become dependent on fossil fuel usage for revenue and will enact policies that ensure that revenue stream never gets cut off.
I really feel that climate change is totally irrelevant. There is so much other pollution out there and it's all a symptom of massive over consumption, planned obsolescence, negligent/unplanned obsolescence and consumerism.
The quest for things, the newest things, the newest non-upgradable things, is leading us into disaster. We can't keep throwing away phones after two years or purchasing new laptops instead of fixing what we have. We don't have the raw materials to replace the millions of gas cars on the roads with electric/hybrids.
Things like rail, consuming less, paying more for longer lasting devices, smaller factories that produce fewer yet higher quality goods, etc. etc. will fix the underlying problems. Things like CO2 emissions, the massive plastic patches in the oceans, heavy metal in our water supplies, toxic waste--these are all symptoms and not the root problem itself.
It requires a massive change in thinking, advertising and economies. For example, Intel should be happy when it has a massive growth reduction because it means they created something that lasts a long time, is still valuable and is non-disposable. Companies need to be rewarded for things that simply last longer or can be upgraded, recycled or refurbished. The fundamental role of money and its representation of resources has to change. Our values about what is valuable needs to change.
Climate change is just a runny nose out there that people try to plug up with pseudoephedrine when the real problem is the virus that's killing your body.
I'd love to hear your thoughts on how those issue can be solved that doesn't involve totalitarianism or in other ways infringing on people's rights. Because the problem you're trying to solve has been attempted by many murderous dictators in the past. "But this time is different," they all say, and it never is.
What about taxing things on the consumer side? I know a number of municipalities that charge people per bag of garbage.
What if that were extended based on toxicity? Enough so that throwing out year old electronics started to get expensive enough that consumers started valuing longevity again?
I don't think you'll get US buy-in for any sort of manufacturer-targeted externalities tax. See carbon tax debate. But, if you tax the consumer (either on the front or back end), demonstrate that the tax revenue is 100% funding something they believe in (e.g. toxic electronic waste fee -> parks, libraries, and after-school programs) then you might have a shot.
Part of the problem is that the 60s-00s were in Moore's Law, so there was a finite performance incentive to upgrade devices frequently. I'm hopeful as that changes, build quality becomes a key distinguisher.
In general I agree with you that a technological breakthrough is the only thing that will really help us and that government cooperation will be hard to come by but I do think that lobbying for carbon taxes could help move the needle on how much effort is put into research.
Indeed it is a complex situation. The difficulty is that, among proposed solutions, there are ideas that are being taken seriously that have the potential to drastically slow down the economy, decrease the standard of living for millions or billions of people (which could realistically involve people in developing nations starving to death), and massively increase government control over our lives.
Now I get that all of these things may be required to save the planet. But the alarmists have been warning of impending doom and destruction for decades now, and everything is still fine. So maybe let's practice some level-headedness and stop disingenuously pretending that the skeptics are just stupid extremists?
With all due respect, I don't think so. Program lifetime cost of the F-35 Lightning is projected at a whopping 1.5 trillion US$. For the same amount of money, you could bring the renewable energy level to 50% of US electricity consumption (~1 US$/W). Scale effects not even included. Nobody wouldn't even miss the fighter (well, nobody missed it for all the years it was late).
It would be a concentrated effort of just 5 years going all the way at the scale of the Manhattan or Apollo projects, just a question of somebody really wanting to do it. It's just that it's way less sexy.
Isn't the 1.5 trillion number the total cost projected out to 2070 or so? (with maintenance included)
You can't take the cost of the whole program to 2070 and then state that nobody would miss the program. Not saying that defense budgets aren't up for debate, but your line of reasoning is not convincing.
Would spending $1.5 trillion from now until 2070 (the time horizon for the F-35 expenditures) avert climate change? Or will climate change happen anyway, and the only consequence will have been a reduction in our abilities to fight other countries for dwindling fresh water resources?
Everything is not fine, however. We are currently experiencing the effects of global warming. In the first world we are largely insulated from this but we've seen more frequent severe weather (of the 15 busiest hurricane seasons on record -- with records dating back to the 19th century or so -- 10 have been since 2000). Severe drought and heat have also become more common. We've seen migration patterns of wildlife change and that has lead to impacts on communities that rely on those for their livlihood (native communities for example). We've seen the sea level rise 88mm since 1993. There have been real impacts. Just because we don't feel it in the first world, doesn't mean people haven't been impacted.
What do you do about the expansion of populations (http://www.nzdl.org/gsdl/collect/fnl2.2/archives/HASH8cd2.di...) in developing countries that are still waiting for rapid growth? Intuitively, as they transition to developed economies that will come with greater CO2 emissions. Do you force them to adapt less economically viable sources of energy consumption? Natural gas may be the best bet there. I am not holding my breath for solar power and wind turbines to be adopted by countries that still face widespread malnutrition.
I don't think democracy and liberal capitalism will have any consequential solution to global warming, people are too inherently motivated by short-term and local gain. Unfortunately, any massive change will probably have to be dictatorial/authoritarian/militant, what are the byproducts of that?
The cost of solar is dropping fast, and for the time being the largest emitters per capita are developed economies. So we should start in developed economies, were we can spare the effort and then work on developing economies.
On the poorest economies, quite a few of them are close to the equator were solar looks very good, plus a rather nice thing about solar is, that it scales very well. In countries were malnutrition is still a wide spread problem, a solar powered lamp enables people to work outside of daylight hours, and a solar oven prevents them from sitting in kerosene fumes while cooking. This are small appliances with a rather minimal footprint, but improves their lives in ways it is hard to imagine for us, who are just used to always having electricity.
Plus, there is not reason to assume that they have to take the same development path as the developed economies. They have the second mover advantage, that is developing economies can avoid the problems western industrialization did create, simply because they can see these problems in the west.
> Do you force them to adapt less economically viable sources of energy consumption?
How about: Voting for policies of boosting the development of renewable energies in the US, putting to work all the unemployed of the coal mines, so it's American companies (instead of, say, Chinese) that make them more economically viable than non-renewable sources. So when these countries transition to developed economies, they become consumers of American manufacturing.
How about: that the contribution by humans is unclear, that we may be able to resolve issues that do arise and/or that adaptation is a viable solution?
The contribution by humans is unequivocal. If you would like to understand how we know that, take a couple hours and read the IPCC report Summary for Policymakers. It is a fascinating and relatively easy read. It also includes projections based on several different models and estimates the impact on society from those projections.
Also note that the different curves of the projections don't mean that the most probable is in the middle. The highest and the worst one is under the assumptions "if we don't do anything about it" which is exactly what was done up to now!
The lowest one is "if we soon stop using the fossil fuels completely" which is not going to happen.
And to those who don't believe:
It is caused by humans: see the energy used in the last 200 years:
The principle the warming works is the same why you wear a coat in the winter: the coat keeps the surface temperature of your body warmer, even if the coat itself doesn't produce a new heat. A thick coat keeps you warmer than a thin one. More CO2 does the same to the Earth surface. Without the greenhouse gases the average Earth temperature would be 0°F (or -18°C) and it is 59°F (15°C). And "a few degrees more" is really a lot and awfully fast, see the xkcd drawing again.
That's called the "wishful thinking" fallacy, to which you cling to confirm your previous "investment." If we'd look at your sources of the apparent "conflicting" data, we'd be able to see that they are intentionally biased, fabricated, cherry picked or whatever. But I would be surprised that you accept that fact, on average it doesn't function that way psychologically. Which is how humans work, but not a scientific argument.
Anyway, the natural processes, unless cataclysmic, don't make such rapid changes that we experience now. The speed of the change is orders of magnitude faster now than the non-cataclysmic natural ones. It is really going to be worse than most can even imagine. Our children or grandchildren are going to hate us for not doing enough. The politicians and lobbyists who only see their own benefit will be dead and won't care.
To compare with the "good old times": the study of human DNA shows that 70000 years ago, only 2000 humans survived one extinction event:
Whether or not it's caused by humans isn't relevant. If it's a problem, regardless of the cause, we ought to be thinking about what we can do to avoid it or to adapt.
So I don't understand why so much of the left chooses to frame the issue in such a way that makes it contingent on that cause.
Is it really? Would it not be easier to find consensus (hence more productive) if we were to focus on whether the climate is changing (and not why)? Determine what the impact of the climate change will be and how we should address this problem?
I have to admit I'm baffled by this line of thinking. Since coal-fired power plants are a primary driver of climate change, it makes sense to stop using them in order to help avoid further contribution to climate change. If they didn't contribute to climate change, then that incentive to stop using them would not be there. Understanding the causes of climate change directly impacts what policies we implement to mitigate it.
I think here's where you're going wrong. There's a difference between "is caused by" and "contributes to".
It would be internally consistent to form an argument that supposes an alternate root cause, e.g., solar activity cycles and cycles of the Earth's magnetic field. One can state that these natural problems are (hypothetically) the root cause, while still acknowledging that CO2 is a greenhouse gas and thus decreasing our CO2 emissions - even if we weren't doing anything naughty on our own - might serve to mitigate the damage expected to be caused by those long-term natural cycles.
I... guess? That hypothesis conflicts with our best data and you end up at the same policy results anyway, so I'm not sure why one would prefer that roundabout method instead of simply agreeing with the scientific consensus.
You switched topics. They were talking about contribution (albeit enough contribution to be the main cause), and you tried to make it as though they were saying causation (meaning no other causes).
The common jargon in Liberalese is "anthropogenic climate change", i.e., climate change created by humans. My argument is that they'd have an easier time getting people on board if they went about this without assigning blame.
Saying "there's a problem we need to solve" is going to get a more productive reception than saying "you created this problem and now we need to solve it".
maybe one should instead push something wacky, like that the great spaghetti monster caused global warming... [insert missing logic] ...and that's why we should shut down coal plants.
How would someone go about it, and would you trust them?
It's not that we should not do what you're suggesting but clearly we're not able to due to political differences. I'm suggesting that we may need to take a different approach to tackle the problem that considers political realities. Trying to reduce the carbon emissions is not the only way to address the climate change, many people argue that it may no longer be sufficient anyway. Suggestion is to focus on the fact that it's happening and try to find ways to reverse it, mitigate it's impact etc.
The impacts i clude the possibility of humans being literally unable to survive on some parts of the globe if wet bulb temperatures become high enough. And a constantly shifting coastline requiring recomstruction of the coastline every decade.
That's if we keep burning all the carbon. Yes, causes are important.
So you're saying that we need consensus to do things now? My sides are splitting.
Can you name a thing that you think we have "consensus" about?
edit: and wait... "easier to find consensus"! I admit you lost me there. We just don't live in the same world. Do we have consensus for the policies we have now? So what is the justification for favoring them?
Even if it's maybe not clear to you or to those you like to believe, it's still clear to the relevant scientists of the whole world.
"Total radiative forcing is positive, and has led to an uptake of energy by the climate system.
The largest contribution to total radiative forcing is caused by the increase in the atmospheric
concentration of CO2 since 1750 (see Figure SPM.5). {3.2, Box 3.1, 8.3, 8.5"
"Human influence on the climate system is clear. This is evident from the increasing greenhouse
gas concentrations in the atmosphere, positive radiative forcing, observed warming, and
understanding of the climate system. {2–14}"
I think you are reading this table wrong. The table does not list "emissions per GDP" but "GDP per emissions", which is actually the inverse.
So to get the "emissions per GDP", you have to read the table backwards, which means the United States is (among Australia, Israel, Canada) emitting more CO2 than most other developed countries, in particular Western European ones. For example, Germany produces roughly 60% more economic output (3,612 USD / ton of emissions) per CO2 emitted than the United States (2,291 USD / ton) and the United Kingdom (4,284 USD / ton) almost twice as much.
[Update: Of course, all of these figures are not that helpful because they ignore how much CO2 emissions one "outsources" by buying products manufactured elsewhere. If you are primarily a service-driven economy, you will have much lower CO2 emissions in your country, but you will most likely still buy a lot of stuff from China etc. which will produce CO2 emissions there. That's e.g. why Switzerland is not as green as it would seem from this table.]
Emissions per GDP is a bit of a weird metric, don't you think? It disguises major variations within individual nations' economies.
It's hardly surprising that a developed-world, service economy would produce fewer emissions per GDP than a developing economy that is geared toward mining and manufacturing.
It's also worth noting that the likely benefactors of those developing-world emissions are the people in developed countries. So even regional estimates of emissions, let alone emissions per GDP, probably miss the point.
It seems that way. But considering that so much of the emissions are produced in the course of producing goods, it makes sense to tie the emissions to the production. In the extreme case, where a single nation produces all goods consumed by the world, we'd expect the large portion of global emissions to come from that one nation, and the emissions of the rest of the world to be very significantly lower.
Obviously this isn't perfect. Other activities than production produce emissions - notably transportation. But I believe that those dollars are captured in the GDP total.
I think we then get down to "which people are profligate consumers", and I'm not sure how to factor that in.
These industries are emphatically not equal contributors to greenhouse gas emissions. So it makes little sense to aggregate them and measure the emissions to GDP ratio.
> I am really not impressed by any sides efforts to combat global warming.
The reality today is that no efforts are made whatsoever by any political movement on the planet to combat global warming, in the entire planet (except perhaps the CPC of China, against all odds). American Republicans do not even have the hint of honesty of admitting the issue at stake. They denied it 10 years ago, now they want to turn their audience into believing that it may not be human-caused.
> I would love to see more discussion beyond conservatives are anti-science radicals who want to kill the earth.
The discussion was over dozens of years ago, there is no debate. Human activity (intensive farming, petroleum and coal burning, cement production, ...) is causing climate change, period. And the changes are already past the point of being reversible. The data is plentiful and everywhere for the world to see.
If the media were unbiased and wanted to show the viewers the actual state, there would be always 20 scientists in the studio, 19 scientists speaking that the global warming is real and only one speaking that he believes it's not. Then every viewer would understand.
"One person per side" is the core of the problem. That's how people get the impression it's 50-50: on the question "most scientists think global warming is happening" unsurprisingly only 49% of the public answered yes. They always see on the TV, at best, one guy speaking against another guy. The impression then: 50-50. It's not.
>>The reality today is that no efforts are made whatsoever by any political movement on the planet to combat global warming
I don't think that is true, in the UK there have been efforts, for instance our coal use is the lowest for 150 years[1]. It isn't anywhere near enough to solve the problem but it isn't nothing either.
True, thanks for the correction. The point that I wanted to make was that all the efforts underway around the world at their current magnitude are not gonna make a dent in the greenhouse gases generation curve.
The "debate" means "a formal discussion on a particular matter in a public meeting or legislative assembly, in which opposing arguments are put forward and which usually ends with a vote."
If 95% of the scientists of the whole world agree the global warming exists and is human caused, that "formal discussion" is really over since 1990. Since then there was no debate if. You can read the results of that discussion in the IPCC reports, the last summary here:
If you mean that the politicians would like to "debate" between themselves "what to do about it," they sure do. But they shouldn't be allowed to doubt all scientists of the world. It's criminally irresponsible, considering the potential dangers.
It's also extremely simple in basic principles: without naturally occurring greenhouse gases, Earth's average temperature would be near 0°F (or -18°C) instead of the much warmer 59°F (15°C). More greenhouse gases, the higher the temperature on the surface. The same way you cover yourself with the blanket, under the blanket it's warmer, not because you produce more heat but because more warmth stays under the blanket. It's that simple, as simple as wearing the coat not to freeze in the winter, and unbelievable that somebody can be manipulated to doubt it.
P.S. Surveys of scientists' views on climate change (to answer the question to this post):
On one hand that seems fairly reasonable, on the other hand I can't escape the feeling that the author had a conclusion and was fitting results to it. It is an inherently messy and complicated field and there are many ways one could interpret this largely qualitative data, but the author seems to have not a shred of doubt or uncertainty, for my type of personality it makes my spider senses tingle.
One of the problems with Cook's appeal to authority is this: So far, no one has quantified the consensus among natural scientists on global warming. In fact, it cannot be done easily, said Jon Krosnick, a social psychologist at Stanford University who has been studying communication strategies for decades.
While the Cook study may quantify the views expressed in published literature, it does not establish the beliefs of any defined group of scientists, Krosnick said.
"How do you determine who qualifies to be surveyed and who doesn't qualify?" he asked. "Personally, I haven't seen anyone accomplish that yet."
EDIT2: This might be an interesting read if it wasn't behind a paywall:
But even for the simplest, back-of-the-napkin calculations, you'd have to deny the contribution of CO2 to conclude anything else. And the CO2 contribution is 100% proven.
The same stands for the basic chemistry: The humanity burns immense amounts of carbon, burning hydrocarbons produces CO2 (if there's enough fresh air) or CO (if there's not). If you don't believe that, I suggest you to close yourself in a sealed room and burn a fire (coal) inside and keep it burning. You'd die, provably, unless somebody rescues you.
The concentration of the CO2 increased proportionally to our burning of the hydrocarbons increased, and additionally, the seas got more acidic. Everything fits.
P.S. If you "just" doubt in the study of over 12,000 peer-reviewed climate science papers, you are free to evaluate them yourself and to publish your take on them. I really doubt that the results would significantly change, if the scientifically valid methods are used. I have emphatically not called you personally a "denialist." But I argue that you can't be intellectually honest if you use an "argument from incredulity" (which you suitably call your "spider" that is, in reality non-existing, non-sense sense) or stating "there are many ways one could interpret this" which obviously isn't true. You linking to the work which main conclusion is "that partisan presentations of controversies stifle debate" has also no relevant scientific value, as the scientists agree about the human caused global warming occurring at least 30 years already. There are scientific facts, and to establish other facts you have to do real scientifically valid work. Scientifically valid also means accepted by the scientists. The majority of them in the relevant field. Again, politicians, lobbyists and media don't count. It's very known that the US public perception of the scientific agreement is wrong (including OP the statistics we comment), and your "spider sense tingling" (your name for you avoiding logically and technically valid arguments) fits that exactly.
Simple, honest skepticism, what used to be considered an intrinsic part of the scientific process, literally isn't an option? The irony. :)
Note that in this case I wasn't questioning the science of global warming, I was questioning the methodology and manner in which they qualitatively reviewed these scientific papers. There are, in fact, many different conclusions one could draw, depending on your agenda. Presenting it as nothing more complicated than simple math seems suspicious. Being accused of being a "denialist" when pointing this out is cringe worthy.
It doesn't need to be, anyone with the most basic understanding of the issues or anyone who cares enough to do the most basic cursory examination of the facts knows exactly what's being referred to.
There simply is no worthwhile discussion to have about whether or not human activity has been a cause of climate change. 'Debating' it is akin to debating the existence of gravity or a causal link between smoking and cancer or whether or not quicksort is better than bubblesort. That is, it would be similar if there were a very wealthy and powerful 'bubblesort' lobby that funds and props up any argument that favors it, no matter how ridiculous or how much bad faith is required to make it.
Well, in fact researchers recently found that second-hand smoke probably isn't harmful. And that's exactly the point, things that some people think are settled are far from settled. And that kind of attitude invites suspicion. Why are you so concerned by skeptics?
I don't have a problem with skeptics. They're a healthy part of the scientific ecosystem. But as devil's advocate style checks against the consensus, challenging premises and acting in an adversarial but respectful manner.
Many of the climate change skeptics actually allege a huge conspiracy and accuse the enormous consensus of educated scientists of lying or being fundamentally incompetent, which puts them on the level of cranks that don't deserve a moment's notice. But there's a lot of money and prestige in denial, it's a huge business because the longer we deny the more money certain large companies can make. So these cranks (and the minuscule fraction of qualified honest skeptics who barely exist) get credence and money far beyond their due. They get paired off 1-on-1 with an actual scientist in the public sphere. They get asked to speak on commissions. Which is what I have a problem with.
I don't have a problem with John McAfee existing. I'd have a problem with him and Ron Rivest holding a public 'debate' about RSA to 'understand the controversy'.
And you'll notice I never mentioned second-hand smoking. Evidence has always been shaky and arguable about how much of an effect it has, it simply followed the same moral panic as the very scientific smoking evidence. And we found out we were being lied to and results were being fabricated and manipulated by extremely powerful interests about smoking, so to be on the safe side we chose to trust nothing pro-tobacco after that, a correct choice I think. A societal immune response against the cancer that infected us, if you'll pardon the appropriate analogy.
I picked smoking as an example because the evidence is incontrovertible and because it was covered up as long as possible by actively malicious corporations and lobbying groups with the intention of killing as many people as possible so that they could sell more cigarettes to unwitting innocents/children. It's a history lesson that we should give very little credence to "skeptics" who happen to always end up having connections to vested corporate interests and insist "the science just isn't settled yet" but provide no evidence to back their contrarian claims and insist that we should drag our feet. Sound familiar?
My experience is that "conservatives" will pick whatever argument they can get away with when it comes to climate change. Depending on the context the same person might argue:
1. Climate change is a hoax.
2. Climate change is real, but natural.
3. Climate change is real, caused by humans, but beneficial.
4. Climate change is real, caused by humans, harmful, but attempts to fight it don't help.
5. Climate change is real, caused by humans, harmful, can be fought successfully, but the cost isn't worth it.
I too would like to see more productive discussion, but it's hard when every discussion on the subject is flooded with people arguing in opposition to the facts.
But what you're complaining about isn't an issue with conservatives; it's an issue with asshats. And if your goal is to convince an asshat of something, you don't talk to the asshat. You talk to (and convince) the person the asshat respects.
If someone barges into an discussion like that and you attempt to confront them with reason and argumentation, you're gonna have a bad time only further poisoning your perspective of the "other side".
It's an issue with climate change deniers specifically, which has nearly total overlap with the set of conservatives.
And sure, this sort of thing is not unique to climate change denial. What is unique is the consequences that denial is having to the planet (and therefore me), and their presence in forums that are otherwise at least vaguely aligned with facts.
How is their denial affecting you? Has it led to tangible changes in your life? Maybe you'd argue that it has led to a lack of tangible changes, but I don't think you can stand on that. Environmentally conscious efforts have continued to grow year after year despite a lack of political consensus, ultimately leading to solar now being cheaper than coal. That isn't due to regulation. It's because people who care have found ways to make a living doing the thing they care about and making it more viable.
tl;dr: People may deny the problem, but when the solution isn't political in the first place, I can't see why it matters.
The problem is being made much worse than it would be if our government accepted the science.
Yes, renewables are getting quite cheap, and coal is dying one way or another. But the amount of coal that gets pumped into the atmosphere before we're done with it will be far higher than it needed to be.
If you think the solution isn't political, then obviously you'll disagree with me, but you're unlikely to convince me that government intervention doesn't matter here.
No offense, but what kind of crazy metric is that? "Wealthy people get to pollute more?" "It's OK to ignore emissions until everyone is as wealthy as we are?" I mean, I could spend hours and hours churning out moral hazards based on that analysis.
It would never fly with other subjects: "handgun injuries per taxable income" shows that only the poor get shot, so it's not really as much a problem as you think.
My vague guess is that you're trying to use "GDP" as some kind of proxy for "industrial output", and saying that while the US emits a ton of CO2, that's OK because we actually need to do that to produce all the wonderful thigns we do. Except that's not what GDP means at all, and industrial production stopped being a dominant fraction of that number like a century ago.
Having lots of web developers and Starbucks franchises in our economy doesn't give us a license to pollute.
(Edit: literally minutes after I posted this, there's a WaPo story up saying that the Trump administration is floating the possibility of a carbon tax of some sort. So maybe there's some hope for conservatives after all.)
As a conservative, I can tell you that left-leaning politicians will not be effective at combatting climate change so long as they are up against a right wing obstruction machine.
(For the record, I am stuck between supporting crooks and hacks who claim to be conservative, and supporting liberals, and so I'm backing liberals for the duration.)
Thank you. I hope in the near future we have a party that can reflect your views without rejecting reality. The only way to bring Republicans back into reality is to stop rewarding them for insanity.
I am also very unimpressed by anyone party's effort to combat it, but as this map exemplifies, we aren't even at that stage f the conversation yet with many folks. We NEED to be talking about how to combat it, but instead we're spending all of our time arguing about whether it exists. Which is insane! We're frogs sitting in a pot of water that's about to boil and arguing about whether it's getting hotter, instead of talking about how to jump out.
I'd love to be having policy conversations about solutions instead of doing that.
Most proposed "solutions" to this problem directly attack multiple people's livelihoods. They can, should and must defend against these things tooth and nail. Expecting otherwise is naive.
Real solutions look like building out a renewable infrastructure. A thing that is happening everyday already, spearheaded by humanely conscious individuals and companies (Google, Apple, etc). There is literally nothing for the government to do in this situation but get out of the way and facilitate such endeavours.
I remember a presidential candidate proposing a solution that was boosting the building of renewable infrastructure and technology, so exactly what you propose.
I think calling that a "humanely conscious" government, as you say, would have been appropriate too.
I'd rather that president lower my taxes and leave the infrastructure business to companies that actually understand how it connects to everything else.
Yes, I would be against any program developed for military reasons. NASA has produced a ton of amazing things. But they did it so we could blow people up.
> In my experience with some conservatives, it seems that they believe global warming is happening but they are skeptical of how effective left-leaning politicians can be in combating climate change.
This is a major point. It's not that conservatives (in general) don't think it's happening, but believe that the solutions provided won't yield results to how expensive or "sacrificing" they are. Especially when you have big lobbies involved and especially when you consider China and how they have no real plan on cutting emissions.
China is the world's biggest investor in solar technology and hopes to grow its solar power to 20GW by 2020. [1]
China forced all taxi drivers in Beijing to use electric cars, a desperate and very controversial move. [2]
China is highly subsidizing its high-speed rail companies, bleeding billions of dollars per year, to cut other transportation methods. [3]
I am not saying to follow their example (some of their actions are probably not the best investments, environmentally speaking), but saying they do not have a real plan is quite untrue.
And China's example proves nothing here. Am I supposed to be surprised that an authoritarian government somehow finagled the political capital to invest in industries guaranteed to be highly disruptive to its most major economic competitor? Cuz I'm not.
My point was to prove the fact that China does have real plans to cut on emissions. Your answer is that their policies are economically viable and future-proof. I don't understand what is your point.
Conservatives love spending huge amounts of money for a good return, that's how we've gotten cheap solar, for example. They also have excellent time preference and planning for the future, accusations of the contrary run into observed examples of who actually is wealthy for all scales of wealth.
To expand upon the conservative reasoning:
Suicide never fixed anything. Killing our own economy and literally killing our own people makes some people (suspiciously never the people doing the suffering...) feel better about themselves not being as guilty. But lets face it, unless you can get "cult leader" levels of suicidal thinking into the entire species, human #235325 sacrificing himself and his family merely means human #85735 over there is going to burn the coal and oil, perhaps a little later. All the "conservation" stuff has no impact on the earth. A history book a million years from now would read something like "all the coal got burnt; some felt holier than thou for not personally burning; but it all got burnt" For some, being anti-suicide is a religious belief. For others, its just common sense. Why should I kill my kids so they don't burn coal which supposedly makes them holy, when someone else's living kids will burn the coal anyway? Why can't those people simply accept cyanide pills for themselves and their families, why do they insist on dragging us into their death cult kicking and screaming? In the long run from the earths point of view what does it matter if its all getting burnt anyway? Will mother nature "feel better" knowing a Chinese dude burned the oil instead of a rural white guy burning the same oil?
Wisdom about time is stronger on the right than on the left, see financial investment for example. Or just simple time preference WRT criminality statistics. Lets say we have to kill a million americans by ripping away their jobs and forever dumping them into drug addicted rural poverty without medical treatment leading to young death, lets really make them suffer because thats what we need to do to lower the carbon rate by 5%. Whats the result of all that human suffering? Well, the same sea level rise will happen and same climate change will happen, just maybe a couple weeks or months later. Perhaps the next ice age will arrive a few months sooner. But the human cost, oh my God. From a moral or ethical standpoint its pure evil to torture people just to move a date on a calendar that doesn't matter anyway. Its pure evil, basically. Many things are inevitable such as death and aging. The best measure of a human being is in how you face the inevitable. Grotesque slaughter and torture says more about the people proposing that "economic fine tuning" than they want made public. I would rather bravely face a 30M sea level rise on November 23rd 2071 than shoot my neighbor's kid in the head today to face the same 30M sea level rise on November 24th 2071. Sociopaths will do anything to get ahead, but conservatives have moral and ethical standards. Conservatives frankly are just braver people. Look at military demographics for example. I could support environmental policies that will ensure my survival a little longer, but what good is mere survival if you have to become a monster to do it? You have to truly and deeply hate your fellow man to support "economic fine tuning" like is usually proposed, have a deep desire to experience other's suffering and pain, especially of the unwilling, of the lower social classes. I'm not libertarian enough to say that's an OK way to look at the world.
Some are not part of social groups where holiness signalling spirals would benefit them so they don't bother signalling. If all your academic friend retweet your guilty terror of global warming you get a big payoff. If you don't, you're not "cool". You have to do this thing. The thing don't mean anything its just what you have to do to be cool. Not everyone hangs out with degenerates, frankly. Or their personal variety of degenerate gets "twitter cred" quoting the bible or just being a normal human or whatever. Just saying a lot of noise in the system comes from metastasized social media. A cancer of social signalling that only benefits itself and its own growth rate while lowering quality of life. Some ideas are just bad in a certain moral or ethical sense to propagate. Some folks have religious prohibition of proudly publicly being "holier than thou" and frankly thats good.
This is actually a fantasy that has no basis in reality.
You claim that conservatives "(in general)" do believe in global warming but poll after poll after poll demonstrates otherwise[1]. 85% of Republicans don't think humans are to blame and (by extension) there's nothing we could possibly do about it. The Republican President claims quite emphatically that it's a "hoax." How do these observable facts jive at all with your claim that conservatives don't believe in the "solutions" when most don't even acknowledge the problem.
As for your fantastic claim that China won't cut emissions again, I suggest looking at reality. See the Climate Action Tracker for China [2]. China is on track to achieve its peak admissions by 2030 which is what they agreed to under the historic Paris Agreement.
The facts are out there. There's no need for you to make up fantastical claims you just have to have the courage to look at them.
> In my experience with some conservatives, it seems that they believe global warming is happening but they are skeptical of how effective left-leaning politicians can be in combating climate change.
Interesting, I was under the impression that most conservatives were climate change deniers (or at least mild deniers as in it may be real but not a big deal).
That being said, a conservative friend of mine argues that what we need to solve environmental issues (and GW in particular) is more growth, more production and consumption. In his opinion, a side effect of this will be more investment in research and eventually new solutions to the environmental problems (as it has happened many times in history, for instance, think of horses being a nuisance in NYC). I would call that a serious leap of faith, but at least there's some logic in the reasoning!!
A better example than horses would be the decline in solar prices over the last half century. No amount of asceticism, or holier than thou preaching, or apocalyptic ranting, or suicide, or willful destruction of the economy could produce that graph of capitalist cost decline in solar energy. Enormous effort on the brains of STEM people, sweat from the craftsmen building and staffing the factories, bean counters financing incredible expenditures... that's how that cheaper than coal solar panel got made. Doesn't matter if one or one billion flailed themselves or felt really guilty, the rise of solar energy is a triumph of the right and capitalism not the left. Thaaats how coal dies as an energy source.
We didn't leave the stone age because of social status signalling holiness spirals declaring the in-group hates stone and stone workers. Or by making everyone feel guilty about the earth only having a finite calculable amount of usable stone. Or by patting ourselves on our backs for a job well done by lowering the third derivative of stone use to a slightly lower yet still large positive number.
> Of course this will be met by criticism from HN, but I would love to see more discussion beyond conservatives are anti-science radicals who want to kill the earth.
+1
I noticed that even in the Yale study, the options on solutions were limited to those with broad left of center options.
Other options, include some that have been pushed by people right of center to address climate change, were not listed. E.g., nuclear power.
Then start insisting that right-leaning politicians take action on climate change. Left-leaning politicians don't have a natural monopoly on combating climate.
(1) For most of the country, 40-70% of the folks in sample say they are concerned about global warming (GW); (2) Areas of widespread (70-90%) concern are limited to the west and northeast coasts; (3) Many people believe that scientists doubt GW too; (4) That all notwithstanding, many folks across the land believe that we should reduce CO2 and take other green steps; and (5) Nearly everybody thinks that this issue has been over-talked – that the talk is way ahead of the science.
Note to opinion-makers: talk about cleaning up more and GW less. You are turning off your audience and volume won't change that.
The most interesting thing I found was that a strong majority, everywhere, claims to trust climate scientists about global warming. But huge areas of the country disbelieve the fact that most scientists think global warming is happening! I'm not sure whether this reflects widespread cognitive dissonance, or merely demonstrates the effectiveness of propaganda.
It seems it is likely easier to convince people scientists don't believe something than it is to convince them scientists are stupid or lying.
I guess all you need is one of those "He Said/She Said" TV interviews where you get one of the vast majority of scientists who believe something on one side and one of the minority who disagree on the other side, and then the conclusion is drawn: "Scientists evenly split on the issue! No actionable information is available from Science!"
> Note to opinion-makers: talk about cleaning up more and GW less. You are turning off your audience and volume won't change that.
I think some people are also just burnt out on the overemphasised message and wildly off-base predictions from the early days.
I don't know about anyone else, but when I was in school in the 90's and 00's we were told half of the landmass would be underwater by 2010. Now I know climate science is more subtle than that but I'd not be surprised if some people came away with the message that Scientists are just foaming at the mouth for no reason.
I'm curious about who they surveyed and the methods they used to reach the survey takers.
I have to think that there is some bias in the surveying methods themselves. I don't think that strongly conservative southern voters would be thumbing through a Nature publication in their free time like a liberal intellectual might.
Overall though, I'm with you. Around here its become a foregone conclusion that this is happening but I don't necessarily see many steps taken by the populace to alleviate the symptoms.
"I don't think that strongly conservative southern voters would be thumbing through a Nature publication in their free time like a liberal intellectual might."
That sort of tribalism is the root of the problem.
> Note to opinion-makers: talk about cleaning up more and GW less. You are turning off your audience and volume won't change that.
I think what turned off a lot of people is the transition made by opinion makers from the straight and falsifiable hypothesis "Global Warming" towards the weaselly worded "Climate Change".
Wording matters when it comes to mass communication. Words that were bold and scientific have been replaced by words that are indistinguishable from politics.
Fascinating: 71% say they trust climate scientists regarding climate change, yet only 49% say they think "most scientists think global warming is happening". This would imply it is not necessary to convince people anthropogenic climate change is real, only that most climate scientists think it is real. Very different message.
For most of the population their only daily contact with a STEM person is the TV weatherman who typically goes to great wishy washy lengths to explain that tonights snow fall or last weeks record high are not the sole or most significant primary proof of the truth or falsehood of global warming. Meanwhile clickbait and disaster pr0n movies for generations have implied we all gonna die due to climate change yet for generations life has gone on, and in fact will continue to go on, and the alarmists are looked with contempt similar to pseudo-Christian preachers and cult leaders announcing the end of the world, admittedly for differing strategies but identical reasons, gaining money and power (edited)
So everyone knows most STEM people are honest and that honesty results in our admittedly pretty awesome modern world, while simultaneously their personal daily experience of a climate expert is at best extremely wishy washy and the scam of begging for money and control via the impending apocalypse goes back millennia before modern "climate change" and most people very wisely scoff at it.
The results make sense that most scientists are technically trustworthy, as opinion leaders their politics are less influential than your average plumber's opinions, and apocalyptic preachers have always been full of it and always will be.
For political reasons and tribal reasons, many will have to pretend to be surprised to signal that they're in the in group and the out group suxs, but we all know the above is how the world really works.
Most STEM people are honest? No. Having worked decades as an engineer, sometimes over scientists, I can tell you that STEM people are just as susceptible to human frailty and peer pressure as any other group. Some of them dont need help to be dishonest.
I posit that none of you have any daily experience with science, otherwise you'd appreciate that 95 percent of PhDs dare not stand up against the groupthink. You would also appreciate how much if clumate science is total garbage.
What an echo chamber. Thankfully, the political pressure to accept climate orthodoxy is currently waning.
And i give a damn about your downvotes, or your unqualified replies.
Well, I'll give you credit for pointing out I meant relative applied honesty.
An EE calculating a resistor for a circuit has a certain applied relative honesty such that either he's truthful about 2+2=4 and the circuit works or he lies and the 2+2=5 and the circuit doesn't work. That times 300 days/year time millions of engineers times centuries of progress equals our pretty freaking cool miracle of a modern world. Some individuals sometimes cheat when they play poker, or lie about politics, whatever.
On the other hand consider a line of work inherently relatively on average dishonest like marketing a dish soap via TV commercial method of marketing. No amount of extra lying will eventually construct Hoover Dam or land men on the moon.
> Half of the participants got a future-focused message, like “Looking forward to our nation’s future, there is increasing traffic on the road.” The other half were given a past-focused message, such as “Looking back to our nation’s past, there was less traffic on the road.”
> After reading the message, the participants took a survey about it and their opinions on climate change and the environment. Participants who reported that they were conservative rated the past-focused message more positively and showed more pro-environmental attitudes in the survey.
Also my main take-away. You could think people are misinformed, and scientists speaking up louder could help, but I think ignorance might be an excuse people use to explain their inaction, otherwise you have to recognize that although climate change worries you, you prefer to keep it at the back of your head because it complicates your daily life too much.
Here's an org that is communicating what many scientists believe through language that attempts to bring divided people together to fight a common enemy. They use WWII programs as a touchstone: http://www.theclimatemobilization.org
everything is physics at the fundamental level, but that doesn't make physicists qualified to talk about everything. Climatology is its own field tied to Meteorology - https://en.wikipedia.org/wiki/Climatology
I didn't mean that I'd expect a physicist to understand every part of Climatology. I meant that I'd expect any competent physicist to understand the basic principles of the greenhouse effect, because that part is physics.
of course, but my understanding is that the debate isn't over whether the climate is changing, but whether it is driven primarily by human activity or a natural periodic system. A general physicist is probably not well placed to answer that question.
People have been trained to be individual consumers of both products and information. They'll believe something so long as it's easy to fit in with their other opinions. There is very little way of me understanding climate change science myself, but I'm willing to believe climate scientists, but this is actually an act of faith, I can't independently confirm that climate change is caused by humans, just say that it's very likely.
My Dad is a little bit like Donald Trump in how he searches the Internet for things which support his already well held views; he thinks that climate change is a hoax. When I quote him this brilliant tweet from Scott Westerfeld:
"Plot idea: 97% of the world's scientists contrive an environmental crisis, but are exposed by a plucky band of billionaires & oil companies."
He just laughs and tell's me about fake news sites he's read as a counter point.
This is a great piece of research anyway; I love that people largely are willing to hedge their bets/beliefs and agree that investing in renewables is massively important, even though a lot of those people don't believe in climate change!
> There is very little way of me understanding climate change science myself, but I'm willing to believe climate scientists, but this is actually an act of faith, I can't independently confirm that climate change is caused by humans, just say that it's very likely.
That's exactly how I feel. I tend to roll my eyes at people that deny global warming is happening, but I equally roll them at people that talk about it happening as if they've done the calculations themselves. It's refreshing to see this sort of humility on HN. Thanks.
I don't roll my eyes at people who tell me carrots are healthier than potato chips, even though I don't really understand nutrition or digestion. There's nothing wrong with trusting experts.
If you would like to have at least a conversant base of knowledge, read the IPCC report Summary for Policymakers[1]. People who do know what they're talking about have done a great job summarizing the state of research, evidence, and probability of outcomes given different projection scenarios. It's not a particularly long or difficult read and you'll come out the other side far more informed than you were before.
> I don't roll my eyes at people who tell me carrots are healthier than potato chips, even though I don't really understand nutrition or digestion. There's nothing wrong with trusting experts.
Nutrition is a specially bad example. There are plenty of studies that are overhyped and make crazy claims about why some food is good or bad for you, but the are not reproducible, have a small sample number, barely reach p=0.05 using p hacking. And a few weeks later you can read a equally bad study with the opposing conclusions.
For example "I Fooled Millions Into Thinking Chocolate Helps Weight Loss. Here's How." http://io9.gizmodo.com/i-fooled-millions-into-thinking-choco... It's a bad study made on purpose, but the problem is that many studies have the same bad methodologies. Are eggs good for you? The food pyramid?
Nutrition is a good example of a field were you have a very complex system and you can´t make very controlled experiments, so it's very difficult to make reliable measurements.
That's _exactly_ the same excuse people use to do nothing for climate change: "it's too complex and there are conflicting opinions, so let's do nothing or not enough"
The dietary variant of this is: "nutrition is too complex, so I'm going to remain fat and do nothing for my health, except maybe get a diet soda once in a while"
This is the most toxic anti-fact position possible and needs to be stomped out with intensity every time it appears. It's the intellectual equivalent of cupping your ears and sticking your head in the sand.
I completely agree. As I said, it's those that recognize that it's a matter of trust that I respect. My complaint was on those who skip that aspect and put the observations on a standard.
Think, for example, of all the times nutritional science has gone back and forth on the healthiness of eggs. If someone were to say that their eating habits are simply following the currently accepted scientific standard, great! But it is less great when considering those that go forward with claims of "Eggs are bad for you, end of story" as an absolute law, with no regard for the context around how they came to know that "law".
> I equally roll them at people that talk about it happening as if they've done the calculations themselves
The two positions are very different though. There is an overwhelming consensus among specialists that climate change is happening (https://climate.nasa.gov/scientific-consensus/). Why would you roll your eyes at someone that base their understanding of the world on the current scientific knowledge?
I think ysavir is making a different distinction. Imagine you talk to three people.
Person 1 says "I don't believe in global warming, because it was unusually cold in my home town this winter"
Person 2 says "I believe in global warming, because it was unusually hot in my home town this summer"
Person 3 says "I believe in global warming, because it is the consensus of climate scientists"
Assume we agree that person 1 is wrong, and person 3 is right. But is person 2 right because they reach the same conclusion as person 3, or wrong because they use the same reasoning as person 1?
That quote says it all: I have no disrespect for people that, as the OP did, acknowledge that they are putting their trust and faith in modern science. The people at whom my eyes roll are those that skip over the trust and preach global warming as a gospel.
It's the difference between saying "I don't know what's going on, but I trust those that specialize in this field" and saying "Oh, I know what's going on (even though I never touched science since high school)." As I said in the previous post, it comes down to intellectual humility.
>That's exactly how I feel. I tend to roll my eyes at people that deny gravity is real, but I equally roll them at people that talk about it happening as if they've done the calculations themselves. It's refreshing to see this sort of humility on HN. Thanks.
This analogy fails because many people on HN have actually taken measurements to approximate the fact that stuff accelerates toward the earth at 9.81m/s^2. I know I did in High School.
Those who haven't seen evidence for the statistical claim of anthropogenic climate change have directly observed stuff fall downward [citation needed].
Interesting to note in this map, the people generally more concerned about climate change are in several types of places:
1) Near coasts. The traditional boring stereotype about the coasts having higher levels of education overall.
The point to notice here is that a some people will see this map, see that obvious fact, and then stop thinking. For example one commenter here said:
>Areas of widespread (70-90%) concern are limited to the west and northeast coasts.
"Limited to." Quite a brushoff. But some of the other hotspots are interesting too:
2) Near mountains. The Rocky Mountains stand out in particular. Because of steep altitude changes, people who live there get exposed in their daily life to many different microclimates in the short span of a few miles as they travel around their locality -- if not by actually changing altitude as they move around, then at least by being able to see from a distance things like the changing leaf colors in the fall, having it essentially in their face what changes are happening and when, each year. Some of these areas have also seen an influx of new pests damaging tree populations in a highly noticable manner, which are suspected to be related to changing temperatures.
3) Near rivers. See the Mississippi for example. I take it the impact of changing water flow patterns raises awareness in nearby communities.
4) For different reasons, North and South Dakota. I would guess the opinions there are influenced by the fact that the states have heavy involvement in energy-related mining activities starting with coal but also with shale and fracking, as well as alternative energy activities like wind power.
Slightly concerning to see so much skepticism. I do wonder if it's a personal choice. By being in denial you do not have to make any changes to the way you live.
Locally they wanted to increase recycling. The answer is to provide offical small bins (140l) that are collected only every two weeks, but collect recycling waste weekly. We've gone beyond the carrot and are now using the stick because many people simply do not want to change.
>It concludes that climate scepticism is largely an Anglo-Saxon phenomenon, found most frequently in the US and British newspapers, and explores the reasons why this is so.
I think its more concerning that skepticism is a bad word in climate science.
The facts are the observations about our climate, I think the conclusion it's changing and humans are causing it is pretty well supported by that. Past there, we're basing policy decisions on modeling (so 1 level removed from observation) and then predicting the effects of those changes on the environment (2 levels removed from observation). So policy decisions based on projected effects in modeled changes to those parameters are pretty far removed from the actual "97% of scientists agree with this conclusion" part of the field.
I live in an affluent area with a good job in a pretty future proof field - it's really easy for me to say "well, who cares if we make the world a better place for no reason". These policy decisions affect a lot of people in negative ways though - to pretend they don't have a valid reason to oppose those changes, and that those policies are based on bullet proof science (especially with the past of climate modeling) is just as anti-science to me as the people who deny the climate is changing. It indicates that a person doesn't understand confidence levels or how errors propagate through layers (especially in an non-linear system) or the difference between an observation, a forecast model and a projection.
Good points. Also - if you believe that we're screwed unless we take action now - we would need to take serious steps worldwide. Which means laying policies on countries that are still developing, where they have serious issues with clean water and people are starving. Where they haven't yet benefitted from investments in serious infrastructure and can't execute those things with renewables. It's much easier to propose these policies from a developed country where we don't have those concerns and already reaped the benefit from little to no environmental rules.
That article suggests that both global warming and deforestation are factors in the loss of the glaciers on Kilimanjaro:
"forests that have disappeared in the past 30 to 40 years on Kilimanjaro's lower slopes -- cut down by villagers for charcoal and open farmland -- were just as much to blame as rising temperatures worldwide"
Anyway this would probably only be a big deal if Kilimanjaro was the only mountain worldwide where glaciers are reducing in size - people only appear to be picking on it because it appeared in "An Inconvenient Truth" and imagining that if that one argument is wrong then the whole edifice of global warming collapses. Which really isn't how science works.
I think social pressure plays an important role. People are more likely to protect the environment if that is common behaviour in their locality and social group. Policy like this is often more reactive to changing attitudes rather than being just a stick.
I would love to see some data on social attitudes towards the environment. Are people starting to dislike big dirty cars?
I rest easy knowing Al Gore and Leonardo DiCaprio have burned far more fossil fuels than I ever will in my entire life.
When someone throws the 'denier' slur around, I throw a giant steak on my Big Green Egg, grass-fed for extra environmental impact.
Edit: I just got off the set of a major motion picture and I've seen firsthand the incredible waste that goes into making movies such as "An Inconvenient Truth" which isn't even a huge production. Don't even get me started on Leo's movies, those soundstages didn't light themselves.
How is it that everyone (82% Nationally) seems to agree that the most critical step forward (Funding Research in Renewable Energy) is a good thing BUT we spend all of our time arguing about whether or not global warming is happening??
This reminds me of a failing, early-stage start up. Rather than just getting to the grind and finding a way to make money, it is so easy to just spend time dreaming and argue about the way forward and spending your time ignoring complaining customers while I'm sitting around pondering how to change the world.
I'd propose its more like you have two partners who hate each other viciously and spend all their time scheming for their dominance and submission of the other. Meanwhile there's programmers trying to ship a MVP. Now as long as the partners verbally argue constantly, they can't screw up what the programmers are trying to do. But if one partner gains total supremacy then they'll need something to do all day, someone to verbally spar with, like maybe the programmers. As long as they argue loudly progress can be made, but once the micromanagement boom falls, all progress will cease, in fact retrograde progress will begin regardless of who "wins".
I can explain that because it's an important data point that should be driving the positioning for the AGW crowd.
I personally think that AGW is overblown, the models and methodologies are suspect and I question human's impact on climate change. However, I can easily get behind renewables.
We shouldn't be dependent upon finite energy resources, many of which are largely controlled by dictatorships. Our investments in renewable clean energy can bring energy costs down for everyone, they're better for the environment (regardless of whether AGW is real, not debateable), and it could keep our money in our country instead of sending it overseas to non-Allied, terrorist supporting countries (hits pro-Trump, anti-AGW crowd). And oh, on the chance that the AGW crowd is right - we also saved humanity for the win! We've all aligned, some for different reasons.
This is the right positioning and the GW alarmists are shooting themselves in the foot because they aren't telling the right story that almost everyone can get behind.
Incredible... the most eye-opening difference was the majority of Americans believe global warming will harm people in the US, but very few people believe it will harm them personally. And this isn't limited to west/northeast coasts-- it covers the entire country. What would cause people to think GW will harm others but not themselves?
To be extremely blunt, yet honest, poverty harms a lot of Americans but its not going to harm my socioeconomic group very much. Ditto heroin, meth... Its an admission of the death of class mobility. Most people will never be economically mobile enough to hang with me and it would be virtually impossible with my social support net to fall into extreme poverty. It could happen. Due to lack of social mobility its very unlikely however.
You can either model the effects of climate change as a parallel argument or merely a cloaked poverty argument. A parallel argument is Hurricane Katrina only hurt people on the south coast but the entire country saw Americans being hurt. The cloaked poverty argument is me and my descendants are in a socioeconomic group that was mildly inconvenienced by the hurricane whereas poor people, and we'll never be members of that group, literally died on TV. Either way Hurricane Katrina is a great example of people being harmed in the USA that could never in a geographic or socioeconomic sense hurt me and my family, or frankly anyone I work with or hang out with.
Unfortunate but true. There's a large amount of people (especially in this country), who feel that way. When they hear in policy discussions "X will harm people", they automatically translate to "X will harm people that can't afford to do Y". When a person's _entire_ social group can afford Y, then its really hard to make them see the need for that policy.
It's not a lack of compassion, it's a lack of visibility.
Not even that. Say there is a random chance of 1 in 1,000,000 that any given person will be struck by a meteorite. In this case, I can quite happily say that the chance that I will be hit is very small, but the chance that someone will be hit is very high (because there are a lot more someones than just me).
If the probability of people being affected is random and independent, then the above explanation holds. If the probability of people being affected is correlated, then it holds less.
For example, say there is a random chance of 1 in 10 that the earth will be destroyed by a meteorite. Then, the chance that I will be destroyed is equal to the chance that someone will be destroyed.
I think for global warming, it will be somewhere in-between.
The general rule of thumb is the farther north the better, although you probably want to be south of melting permafrost. Europe is in for a rough ride, as it will be faced with hundreds of millions if not billions of refugees from Africa, the Middle East, and southern Asia in the not-that-distant future.
So, Alaska, northern Canada, or New Zealand if you can afford to buy citizenship.
It's D3 according to the source file; the type of map is called a 'choropleth'.
Here is a tutorial that might be useful. (I haven't done this specific one but I've made similar stuff before.)

Many times survey does not matter (that much). People will say they are concerned, but their action may reflect they do not really care at all.
Are people at east and west coast really concerned about global warming? Let's don't simply ask them, but check their action instead. Are they selling beach houses? Are we seeing price dropping in beach houses?
I have said this in the past (to climate scientists as well as others) and I'll say it again. Check the energy equations for the climate science predictions. It is easy enough to do, especially if you have a calculator or spreadsheet.
The interesting thing is that the required energy for the predictions is the bugbear and it cannot simply be gotten around. Even the analysis papers that look at the last 50 odd years show a major discrepancy between the energy required and the climate science predictions.
This leads me to believe that the climate science models in use are very problematic (that is screwed badly).
It is also interesting to note that every technology that is posited to be used to replace the current coal based or nuclear based has a high pollution index for the creation of the base elements for these technologies - this is something that is not discussed.
There is also some very interesting biological research that strongly indicates a higher ecological benefit for increased CO2 levels (up to 1000 to 1500 ppm from the current levels) including increased plant growth and lower water usage.
A recent study also indicates that in greenhouse environments, increased CO2 levels has a higher energy transference, that is the greenhouse environment get colder quicker.
So what do we get from all this, as individuals, we can do some investigation into the reasonableness of the climate science predictions and we can come to our own conclusions as to whether or not climate science is sound science. We don't actually have to take the word of either side, we can check the veracity of both sides.
My own investigations have lead me to believe that climate scientists have less an idea of what is causing climate change that do people who have observed the world for 60, 70 or 80 years.
When the models give credible predictions for short, medium and longer term periods then we can start to give credence to what climate scientists might say.
Does waiting for this increase credibility mean we do nothing now. No. We have various infrastructure problems now that need to be solved, some environmental, some energy related, some populations related, etc. Unfortunately, even though there are positive things we can do to mitigate specific problems in the infrastructure realm, the political situation will ensure that these are not done.
Even though the rightists have some good ideas, the leftists will object. Even though the leftists have some good ideas the rightists will object. Any ideas from the middle-of-the-roadists will get shot down by both sides.
So it is up to each of us as individuals to make changes that positively effect our surrounding situations.
Interesting once you start to take into account other countries contributions to global warming. The United States is relatively low among developed economies when it comes to emissions per GDP : https://en.wikipedia.org/wiki/List_of_countries_by_ratio_of_... .
I am really not impressed by any sides efforts to combat global warming.
Of course this will be met by criticism from HN, but I would love to see more discussion beyond conservatives are anti-science radicals who want to kill the earth.
