Yeah, this is one I’m a little late writing on, but if you haven’t seen this yet, it’s interesting.
See that hot pink on the map above? That color is new. While March was warmer than average but not as much as, for example, 2010 or many of the months in 2010 (which broke numerous records), the Arctic (where the most warming has been predicted by climatologists) did see some pretty tremendously warm temperatures (relatively speaking). As a result, climatologists had to add that hot pink color.
Christopher Mims of Grist, where I initially ran across the news, wrote: “last winter the Arctic was more than 10 degrees C (18 degrees F) warmer in than its historical norm (which is defined by the average of temperatures from 1951-1980). So NASA’s scale, which previously topped out at dark red, had to go to 11.” [sic]
Here’s a little more information on March temperatures via Climate Denial Crock of the Week, and another map:
Overall, the combined global land and ocean surface temperature was 0.88 degrees above the 20th century average, making it the 35 consecutive March with above-average temperatures and the 13th-warmest March on record, according to the monthly summary from the National Climatic Data Center.
