Another break in the scientific consensus that It’s the End of the World As We Know It, from Watts Up With That:
January 2008 was an exceptional month for our planet, with a significant cooling. 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 is a quick comparison and average of ∆T for all metrics shown above:
Source: Global ∆T °C HadCRUT
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
This represents an average between the two lower troposphere satellite metrics (RSS and UAH) and the two land-ocean metrics (GISS and HadCRUT). While some may argue that they are not compatible data-sets, since they are derived by different methods (Satellite -Microwave Sounder Unit and direct surface temperature measurements) I would argue that the average of these four metrics is a measure of temperature, nearest where we live, the surface and near surface atmosphere.
To which Daily Tech says:
Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn’t itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.
This doesn’t prove anything definitive, nor would I claim that it does. It is simply another piece of evidence that things aren’t nearly as crystal clear, black-and-white as many in the church, both mainline and evangelical, are assuming it is.
