Except it absolutely DID happen and I can prove it.
Here is a report published in 1999 by NOAA and NASA showing temperatures much higher in the 1930's with cooling through the end of the century. Skip to page 37 and look at figure 6. Note the high point of 1.5 degrees C in the 30's from 1999 data.
Compare this with the same data today and you'll miraculously see the 1930's as much cooler with a warming trend (again, NASA direct data - note the new high point from the 30's is 1.2 degrees C): https://data.giss.nasa.gov/gistemp/graphs_v3/graph_data/U.S....
Here is an article summarizing the alterations in case you do not want to read the NASA/NOAA report, but I know you will attack the source, which is why I published the report from 1999 and the same data from 2019 directly first. You can verify everything in this article with the original source materials using the links shared previously: https://realclimatescience.com/2020/10/alterations-to-the-us...
Before I start to even consider these sources, can you tell me in a clear yes or no answer whether they show:
(1) that the data was altered
and
(2) that the data was altered to suit a political narrative.
Only if the answer to both is yes will I even read any of this. I'll wait.
(Why am I being difficult? I believe you're a typical nutcase who sees X happening, and immediately concludes that "X is happening to fit the political narrative")
> So, I've proven conclusively that NASA altered their temperature data in the 20th century from a cooling trend to a warming trend.
So this is your new claim. Please write out in clear text that you've moved the goalposts since last time – make it clear what you're claiming now. Then I'll be happy to consider your sources. Just wanna make sure you don't move the goalposts again - as dishonest crackpots tend to.
Ah yes, the last stage of the crackpot: "do your own research"
I'm not asking you to do work for me. I'm asking you to clearly state your claim so that you can't move the goalposts again. The fact that you've done it once, makes me certain you'll do it again and thus invalidate any work I do. State your current claim in clear text, crackpot.
