2016 Is Blowing Away Global Heat Records
By Climate Central
May 2016 was the warmest May on record, 1.56°F (0.87°C) above the 20th century average. It was the first month since November 2013 to have an anomaly less than 1°C above the 20th century average, a sign of El Nino’s demise.
For the year-to-date, temperatures are 1.9°F (1.08°C) above the 20th century average, according to NOAA, putting it 0.43°F (0.24°C) above where 2015 was at this point. A Climate Central analysis that averages NOAA and NASA temperature data and compares them to a 1881-1910 baseline (closer to pre-industrial temperatures) found that the year-to-date is 2.5°F (1.39°C) above that average, edging closer to 1.5°C above pre-industrial temperatures.
So far, it is likely that 2016 will top 2015 as the warmest year on record, but that depends in part on how the rest of the year plays out. If a La Nina forms by fall, as expected, that could depress global temperatures slightly.
In a mark of how hot the last few years (which saw three consecutive record hot years) have been, NOAA compared the top 10 warmest months globally as of November 2013 to the current list. As of last month, all but one of the 10 warmest months on recorded occurred in 2016 and 2015. The lone exception was January 2007, which was tied for tenth place. Back in November 2003, it was the warmest month on record.
