NASA: May Was 4th Hottest on Record
19 June, 2018
According to reports from NASA GISS, May of 2018 was the 4th hottest in the 138 year global temperature record. This new warmth came as the Equatorial Pacific began to retreat from a cooling La Nina state — which, all things being equal, would have resulted in somewhat cooler than average global temperatures.
