Two Millennia of Global Cooling?
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....(Read Full Post)
