February 2017 was the second warmest February 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 1.1 degrees Celsius warmer than the mean February
temperature from 1951-1980. The two top February temperature anomalies
have occurred during the past two years.

February 2016 was the hottest on record, at 1.3 degrees Celsius warmer
than the February mean temperature. February 2017's temperature was 0.20
degrees Celsius cooler than February 2016.
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.
