NOAA’s National Centers for Environmental Information released their Global State of the Climate report about May 2016 yesterday. Among their findings was that May 2016 was the warmest May, globally, in 137 years of May data. ... the 2nd warmest May was the previous May.

Of course there’s regional variation because weather affects local climate variables, and so for one chunk of the planet (the ocean just a bit north of West Antarctica) it looks like it was the record coldest. And hey things in the US were near average and according to a lot of Gizmodo commenters only the US exists so...

The 20th century average for May is 14.8°C (58.6°F) and this past May was 0.87 ± 0.13°C (1.57 ± 0.23°F) above that. Cutting the Earth into smaller pieces, it was the 2nd warmest Northern Hemisphere in May on record and the warmest Southern Hemisphere, with really seasonally warm temperatures being recorded in parts of Australia and New Zealand.

NASA’s Goddard Institute for Space Studies released their May 2016 data earlier this week and it came to the same conclusion: that May 2016 was the warmest May in 137 years of measurements of global mean surface temperature.
