SCIENTISTS OR TRUE BELIEVERS…..?

The “global warming” community is going to have to decide which they are, I think. I’ve posted about this before, and anyone reasonably open to the data already is agnostic about the man-made, runaway greenhouse that Al Gore, the gunuflecting media, and a certain cadre of “scientists” seem determined to force into the belief system of the American people and the world.

But here’s the latest from the actual peer-reviewed scientific literature, as opposed to the editorial columns of Science, or the latest scary newspaper headline, or Al Gore’s “blockbuster” movie:

“the warmest year in the extended Greenland temperature record [was] 1941, while the 1930s and 1940s [were] the warmest decades.” What their work shows is that there has been no (that’s zero) net warming in Greenland for the last 75 years.

Here’s the story with a link:

A 221-Year Temperature History of the Southwest Coast of Greenland Reference
Vinther, B.M., Andersen, K.K., Jones, P.D., Briffa, K.R. and Cappelen, J. 2006. Extending Greenland temperature records into the late eighteenth century. Journal of Geophysical Research 111: 10.1029/2005JD006810.

What was done
Combining early observational records from 13 locations along the southern and western coasts of Greenland, the authors extended the overall temperature history of the region - which stretches from approximately 60 to 73°N latitude - all the way back to AD 1784, adding temperatures for 74 complete winters and 52 complete summers to what was previously available to the public.

What was learned
In the words of the authors, “two distinct cold periods, following the 1809 ‘unidentified’ volcanic eruption and the eruption of Tambora in 1815, [made] the 1810s the coldest decade on record.” The warmest period, however, was not the last quarter century, when climate alarmists claim the earth experienced a warming that was unprecedented over the past two millennia. Rather, as Vinther et al. report, “the warmest year in the extended Greenland temperature record [was] 1941, while the 1930s and 1940s [were] the warmest decades.” In fact, their newly-lengthened record reveals there has been no net warming of the region over the last 75 years!

What it means
With approximately half the study region located above the Arctic Circle (where CO2-induced global warming is suggested by climate models to be most evident and earliest expressed), one would expect to see southwestern coastal Greenland’s air temperature responding vigorously to the 75-ppm increase in the atmosphere’s CO2 concentration that has occurred since 1930, even if the models were only half-way correct. However, there has been no net change in air temperature there in response to the 25% increase in the air’s CO2 content experienced over that period. And this is the region the world’s climate alarmists refer to as a climatological canary in a coal mine??? If it is, real-world data suggest that the greenhouse effect of CO2 has been hugely overestimated.
