NOAA and JMA also Confirm Record Global Warmth

12/17/2015, 10:32:13 AM

NOAA and the Japanese Meteorological Agency (JMA) have confirmed that November 2015 was the warmest November on record, just as NASA showed earlier this week.


--Warmest November (2015) on record globally for land/ocean surface combined with a temperature departure of +0.97 C. (measured against the 20th century avg.) The old record was +0.82 C. set in November 2013.

--November 2015 had the 2nd highest global temperature departure for any month. The record holder is October 2015 (+0.99 C).

--This is the seventh consecutive month that a monthly global temperature record was broken.

--Nine of the first eleven months in 2015 have been record warm for their respective months.

--November 2015 was the warmest November on record for global ocean surface.

--The first 11 months of 2015 were the warmest such period on record across the world's land and ocean surfaces, at 0.87°C. above the 20th century average.



**Some studies suggest that the cold blob southeast of Greenland could be related to the increase of fresh, cold water into the North Atlantic due to the increased melt of the Greenland Ice Sheet.

--December 2015 would have to record a global temperature departure of -0.81 C. or lower to avoid 2015 as being the warmest year on record.

--The September-November period was the warmest on record globally.

--The September-November period was the warmest on record for land surfaces.

--The U.S. recorded it's warmest autumn on record with every state running warmer than normal.

--Due to the lag effect of El Nino, there is a decent chance that we may see even higher monthly departures from normal during the first half of 2016.



--November 2015 averaged +0.54 deg. C., making it the warmest such November in the JMA database, which is measured against the 1981-2010 average. The old record was +0.31 deg. C. set in November 2013.
