Global Temperature in Decline?





 The bad news for our true believers is that after a dozen years of effectively flat lining about a half degree above the Holocene Norm while the CO2 rise continued unabated whatsoever, it has now begun to fall. This probably reflects the Antarctic maximum been achieved and plausibly injecting cooler waters into the Atlantic basin. This down tick may even turn out to be quite sharp before it is finished.

Watching this happen also gives us a tentative explanation for the abrupt temperature declines observed at the onset of the so called little ice age. In fact I think the expanded Antarctic maximum is the real and present climatic threat. This could be the long term climate driver that is missing. During this period, CO2 rose about ten percent on a global basis (+ 30 ppm from 365 ppm) which likely matched the entire previous increase that was been relied on.

Obviously declining global temperatures with the decadal temperature plateau makes the CO2 linkage just stupid and the global warming argument undefendable. The interesting question will be if an injection of cold water into the Atlantic Basin can also act to sharply reduce CO2 content.


World Leaders Face Riddle Of Lack Of Warming


The most recent global temperature record, released this week, shows the average global temperature fell last year for the second year. There is now general agreement that the rising trend has stalled. This is the background against which governments will meet in Doha to negotiate a globally binding agreement to cut carbon emissions, as agreed at last year’s meeting in Cape Town, South Africa. --Graham Lloyd, The Australian, 24 November 2012
