March set a remarkable new record for global warming, NOAA reports

The National Oceanic and Atmospheric Administration (NOAA) reported that last month set an unusual and unexpected new record for global warming.

No month before March 2017 had ever exceeded the “normal” temperature (the 1981–2010 average) by a full 1.8°F (1.0°C) — “in the absence of an El Niño episode in the tropical Pacific Ocean.”


So when a month sees record high global temperatures in the absence of an El Niño, that is a sign the underlying global warming trend is stronger than ever.

NOAA reports that both March and the year to date (January through March) were the “second warmest on record” for the world since global temperature records began in 1880. They were second only to 2016 which, of course, was a year marked by a major El Niño.

Significantly, both March and Janurary-March 2017 beat their 2015 counterparts easily — even though all of 2015 had El Niño conditions.

It was especially hot last month in the Siberian permafrost,
