RSS Data Shows Warmest January In Satellite Era

05.02.2016 09:02 Age: 2 yrs

Global atmospheric temperatures last month as measured by satellite instruments and analysed by RSS shows that it was the warmest January since satellite monitoring began - following on from the warmest December

oC compared with +0.59oC in January 2010 and +0.55ooC last month making January 2016 the second warmest January in the tropics - behind January 1998 which registered an anomaly of +1.1oC

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 January as warmest in the satellite era and the anomaly in the tropics as being behind 1998. This result in the tropics could indicate that there is less energy in the ocean available to the atmosphere than in 1998 or that temperatures could peak later in the year.
