NASA: June 2017 Was Fourth Warmest June On Record

Here’s the release from NASA (Leslie McCarthy):

The GISTEMP monthly temperature anomalies superimposed on a 1980-2015 mean seasonal cycle.

June 2017 was the fourth warmest June in 137 years of modern record-keeping, according to a monthly analysis of global temperatures by scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.

Last month was 0.69 degrees Celsius warmer than the mean June temperature from 1951-1980. It is surpassed by June 2016 (+0.79 °C) and June 2015 and 1998 (+0.78 °C) and only insignificantly warmer than June 2005 (+0.68 °C).

Except for June 1998, the ten warmest months of June occurred between 2005 and 2017.

The monthly analysis by the GISS team is assembled from publicly available data acquired by about 6,300 meteorological stations around the world, ship- and buoy-based instruments measuring sea surface temperature, and Antarctic research stations.

The modern global temperature record begins around 1880 because previous observations didn’t cover enough of the planet. Monthly analyses are sometimes updated when additional data becomes available, and the results are subject to change.
