If the notion of future generations sounds way too optimistic, you are likely far too pessimistic (if this is about climate change).

There is no realistic scenario for lack of future gens due to climate change in the next 100 years even with absolutely terrible undiscovered positive feedbacks.

I'm not saying there won't be future generations. This is what I was replying to:

> the cost we need to confront climate change is likely larger than the cost in this generation if we let it rip.

I'm saying the cost to confront it will be less than the cost to "let it rip" before some current generations die off from old age.

I think that you are wrong, I am well versed in climate science. The costs to avert now are significant, even more significant than the changes needed for sea level adaptation in our lifetime.

Most of the costs will be borne out by subsequent generations.
