Earth on Pace For Its Warmest Year on Record After a 5th Warmest November
By: Jeff Masters , 8:18 PM GMT on December 19, 2016
November 2016 was Earth's fifth warmest November since record keeping began in 1880, said NOAA's National Centers for Environmental Information (NCEI) on Monday. November 2016 was 0.73°C (1.31°F) warmer than the 20th-century November average, but 0.23°C (0.41°F) cooler than the record warmth of 2015. NASA reported that November 2016 was the second warmest November in its database, behind November 2015. The difference between the two data sets is, in large part, due to how they handle the data-sparse areas in the Arctic, which was record warm in November. NOAA does not include most of the Arctic in their global analysis, while NASA does.
[This is why I didn't put the November ranking in the heading, because of uncertainty over which is more accurate. It seems to me that the NASA ranking would be more accurate since it doesn't ignore the Arctic.]
