1,500 Years of Cooling in the Arctic?

The Arctic is melting, right? There is simply no questioning this pillar of the greenhouse scare, and images of ice melting, polar bears struggling, and indigenous people crying the blues are all part of any self-respecting presentation of global warming. Imagine a study published in a major journal showing that a location in the Arctic has “a trend of -0.3°C over the last 1,500 years.” Of course, you would never have learned of such a result had you not discovered World Climate Report.

The article is forthcoming in Climate Dynamics, and the work was conducted by Håkan Grudd of Stockholm University’s Department of Physical Geography and Quaternary Geology, and despite the results, the research was not funded by industry. The focus here is the Torneträsk area in northern Sweden near 68.5°N (within the Arctic Circle) where Scots pines have been growing for millennia. Grudd not only sampled living trees, but he also collected subfossil samples found as dead wood on dry ground and from submerged logs retrieved from small mountain lakes. Many other studies have shown that the pines are sensitive to summer temperatures, so in theory, the tree samples should allow a very long term and relatively accurate reconstruction of past thermal conditions.

Seems that the medieval warm period was warmer than we thought. THAT may put a crimp into the carbon indulgence sales business.

For the record, I live in Florida and have lived in Arizona's Sonoran desert in the summer without A/C. I LOVE warm weather.
