NASA’s instrumental data set for their Land-Ocean Temperature Index, which goes back to 1880, has updated for April, and it appears that this year’s April is the second hottest on record. Also, we had one of the warmest winters on record, despite appearances to the contrary for those who live under the Polar Vortex. Paul Douglas posted the graphic above showing anomalies relative to a 1981-2010 base period for the months of December through February. Note that there is general warmth across the globe with a few cool spots, including a VERY cold region over North America.
If we do have an El Niño this year, 2014 may be propelled into the record books as one of the hottest years for the last century-plus of careful global measurements of surface temperatures. Remember, this does not count deeper ocean temperatures which combined with surface temperatures are almost certainly higher than ever, because like it or not global warming continues apace.
