|May 2016 was the second warmest May in the satellite temperature record, trailing only May 1998 by 0.11 C, according to data analysed by the University of Alabama in Huntsville (UAH). Map shows average temperature anomalies for the lower troposphere in May 2016.|
The mean global temperature anomaly – or variance to the long term average – for the lower troposphere during May 2016 was +0.55oC, sharply down on the +0.72oC reported in April 2016, and the +0.73oC in March. Compared to seasonal norms, May 2016 was the eighth warmest month overall since the satellite temperature dataset began in December 1978. The decline from April indicates that El Niño has passed its peak.
