Global atmospheric temperatures in February as measured by satellite instruments and analysed by RSS shows that it was the warmest month since satellite monitoring began – following on from the warmest December and warmest January on record.

February 2016 was warmest  month on record in terms of atmospheric temperatures measured by satellite, according to data released by US firm Remote Sensing Systems (RSS).

The mean global temperature anomaly – or variance to the long term average – for the lower troposphere during February was +0.98oC sharply up from +0.66oC in January.

Global atmospheric temperatures last month – like those in 1998 and 2010 – were driven up by an El Niño Pacific Ocean warming event but the data also shows unusual warming in the northern polar region.

The RSS result for January 2016 agrees with a different analysis of satellite data by the University of Alabama in Huntsville (UAH). Both analyses rank the global anomaly in February as warmest month in the satellite era.
