Globally, June 2013 was the second warmest on record, NASA’s Goddard Institute for Space Studies has reported.
The only June warmer than this year was back in 1998 (not all that long ago in the scheme of things), when there was a “super El Niño”. However, unlike 1998, this year we have been somewhere between a weak La Niña and ENSO-neutral conditions, which would usually drive below-average global temperatures. Not this year.
The above image from NASA shows the June 2013 surface temperature anomalies, compared to the 1851 to 1980 average. As you can see, there are some pretty red areas over Antarctica and in much of the northern hemisphere.
