Global Temperature Report – Feb 2014

By Paul Homewood

 

 

It’s ironic that, on the day when the IPCC have released their latest alarmist report, HADCRUT figures come out showing February as the 3rd coldest since 1994. Since then, only the La Nina winters of 2008 & 2012 have been colder.

Background

For anyone not familiar with all this, UAH and RSS are the two satellite datasets, that measure temperatures in the lower troposphere, from the surface up to about 8000 metres. The HADCRUT and GISS datasets measure surface temperatures.

All temperatures are presented as anomalies, i.e the difference, measured against a baseline, that is different across all four sets. (This means that the anomalies are not directly comparable between sets)

The baselines used are:

RSS – 1979-98

UAH – 1981-2010

HADCRUT – 1961-90

GISS – 1951-80

HADCRUT is maintained the UK Met Office’s Hadley Centre in conjunction with the Climatic Research Unit at the University of East Anglia.

GISS is run by the Goddard Institute for Space Studies at NASA.

UAH is the University of Alabama in Huntsville, and their dataset is part of an ongoing joint operation with NOAA and NASA.

RSS is a scientific research company, Remote Sensing Systems.
