US Average temperature changes
August 10, 2007
I uploaded some recent temperature data from NASA to Swivel. I was lead here by a post in the NYTimes to this blog. The largest increases in temps in the past 120 years is 1934, 1998, 1921, 2006, 1931, and 1999. From 1880 to 1920 it was mostly getting cooler. Then there was a warming trend from 1921 to 1959. Then it grew cooler until 1985. The last 20 years have been consistently warmer. It is now 9C hotter than 1820.
