Joe Romm tells us that the hot summer of 2010 on the Eastern Seaboard is proof of global warming.
Compare July 2010 below (hottest year on record) vs. July 1936 above.
The heat this July didn’t compare with July, 1936 – when temperatures were 12 degrees above normal in the center of the country. Not even in the ballpark.
For the entire summer, June-August 1936 stands out as the hottest on record – even after all the upwards adjustments to recent temperatures. Atmospheric CO2 was 310 ppm in 1936, indicating there was no correlation between the heat and CO2.
Belief in global warming depends on keeping people in the dark.
