Global atmospheric temperatures in April 2016 as measured by satellite instruments and analysed by RSS shows that it was the second warmest April and fourth warmest month since satellite monitoring began.

April 2016 was the second warmest April 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 April was +0.76oC, down on the +0.84oC reported in March and the +0.98oC reported in February – the warmest month in the satellite archive.

El Niño drove up the global temperature

Global atmospheric temperatures in April were maintained by the El Niño Pacific Ocean warming event. But they were below those reported in April 1998, another El Niño, when the anomaly was +0.86oC, making April 2016 the second warmest month in the satellite archive.

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