Notwithstanding the latest hysterical claims from the sadly politicized climate scientologists of the National Oceanic and Atmospheric Administration (NOAA), insisting 2011 was somehow "a year of extreme weather," serious investigators at the Johannes Gutenberg University Mainz have just published a sobering analysis in Nature Climate Change which reconstructs 2000 years of climate within northern Europe.
Utilizing tree-ring density measurements from sub-fossil pine trees in northern Scandinavia, the investigators created a sequence dating back to 138 BC. The density measurements are closely correlated with the summer temperatures in a targeted region on the edge of the Nordic taiga, enabling them to create a temperature reconstruction of unprecedented quality. Their high-resolution representation confirmed temperature patterns in the Roman and Medieval Warm periods, but also demonstrated the cold phases that occurred during the Migration Period and the later Little Ice Age.

In addition to depicting these cold and warm phases which were not influenced at all by anthropogenic warming, but rather "by solar output and (grouped) volcanic activity changes" - the new climate reconstruction curve also reveals a striking if unexpected phenomenon. Professor Dr. Jan Esper of the investigative team provided this apt summary assessment of the main findings:

Enviromental-nuts will still claim that is Climate Change. I did see a few people claim the recent heat wave was global warming even after they scolded us for saying the cold proved global warming was false. Ugh.
Why does this chart show a large spike in temperatures at present? I never seen any charts show anything like that.
Last year wasn’t extreme weather. Neither is this year.
Now glaciers covering half of the Northern Hemisphere - THAT is extreme weather.
I don’t know much about the science of anything, but is it not correct that stars tend toward cooling over time? Isn’t our sun a star that will eventually cool and go dark? If that is the case, how can anyone make the case for global warming? Just wondering.
