From 1920-1940 there was a very strong warming in the Arctic, which was causing glaciers to disappear.

Besides the disappearance of ice, pre-2013 NASA temperature records showed the 1920 to 1940 warming very clearly.
As of 1975, scientists showed the 1940 spike for the entire Northern Hemisphere.
But reality completely wrecked their global warming theory, so scientists at NASA and NCDC simply altered the data to make the 1940’s warmth disappear. The animation below shows how it disappeared in their post 2012 graphs.
Climategate E-mails showed their desire to make the 1940’s warmth disappear, which is exactly what they did.

Mike,
Can you delete any emails you may have had with Keith re AR4? Keith will do likewise… Can you also email Gene [Wahl] and get him to do the same? I don’t have his new email address. We will be getting Caspar [Ammann] to do likewise.
Cheers, Phil
An entire field of science is based around fraudulent, meaningless data. And government policy is in turn based on the junk science.
