Global warming in a flash

Climate Central has posted a video based on NASA surface temperature data since 1880, showing how temperatures over the years have wandered from the average. The baseline period is 1951-1980. That's a screenshot above, but you'll have to click on the link to play the video. You've probably figured it out, but blue is cooler, red is warmer, than the baseline average. The video is only 26 seconds long. Watch the US for the drought and dustbowl of the 1930s, and look for the recent changes in the arctic zones.
