[Editor’s note: Ask yourself why the mainstream media haven’t blown the trumpet on this highly significant news. If the change in temperature had been of equal magnitude but upward, you can be certain it would have made headlines around the world, and people like James Hansen and Al Gore would be heralding it as a sure sign of impending disaster.–ECB]

January 2008 was an exceptional month for our planet, with a significant cooling, especially since January 2007 started out well above normal.

January 2008 capped a 12 month period of global temperature drops on all of the major well respected indicators. I have reported in the past two weeks that HadCRUT, RSS, UAH, and GISS global temperature sets all show sharp drops in the last year. …

Here are the 4 major temperature metrics compared top to bottom, with the most recently released at the top:

U.K.’s Hadley Climate Research Unit Temperature anomaly (HadCRUT) Dr. Phil Jones:

Reference: above data is HadCRUT3 column 2 which can be found here. Description of the HadCRUT3 data file columns is here (authorization required).

NASA Goddard Institute for Space Studies (GISS) Dr. James Hansen:

Reference: GISS dataset temperature index data

University of Alabama, Huntsville (UAH) Dr. John Christy:

Reference: UAH lower troposphere data

Remote Sensing Systems of Santa Rosa, CA (RSS):

Reference: RSS data here (RSS Data Version 3.1)

The purpose of this summary is to make it easy for everyone to compare the last 4 postings I’ve made on this subject. . . .

Here is a quick comparison and average of ∆T for all metrics shown above:

Source: Global ∆T °C
HadCRUT – 0.595
GISS – 0.750
UAH – 0.588
RSS – 0.629
Average: – 0.6405°C

For all four metrics the global average ∆T for January 2007 to January 2008 is: – 0.6405°C
