Global Temperature Report – Feb 2014

March 31, 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.

 

  RSS UAH HADCRUT4 GISS
Feb 2014 0.16 0.18 0.30 0.45
Change from last month -0.10 -0.12 -0.21 -0.25
12 month running average 0.20 0.22 0.48 0.61
Average 2004-13 0.23 0.19 0.47 0.59

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.

    The February anomaly is only the 22nd warmest in the series.

    I was also quite surprised to find that this February is about 0.1c LOWER than Feb. 1878.

    I had to double check the figures to be sure.

    The period Nov. 1877 to April 1878 was unusually warm, with March and April particularly high at 0.351c and 0.332c.

    AS the South African guy in the middle of this video says – we are ignoring that because it doesn’t fit with our global goals – at least he was honest.

    Thanks, Paul. Good article.
    Lets hope Dr. Spencer will soon prepare a new UAH vs RSS comparison chart. His last “Differences with RSS over the Last 2 Years”, is at http://www.drroyspencer.com/2012/11/uah-v5-5-global-temp-update-for-october-2012-0-33-deg-c/ (November 6th, 2012).
    Here it looks like HADCRUT4 and GISS are sick, or something.

    Hi Paul, any chance you can re-graph to Jan 2001, ie; the start of the ‘New Millennium’?

    The models indicate that the measurements are in error. ;-)

    The ever-increasing discrepancy between the computer games modelled temperatures and the instrumental readings is disgraceful.

    You would have thought they would have bought some accurate thermometers by now.
