German & Russian doubts on AGW

We are currently at the end of an interglacial era called the Holocene. German and Russian scientists say that it is normal at this juncture for one or more brief spells of warming before the glaciers return. In the Earth’s history there have been eras where the glaciers covered much of Europe, lasting about 100,000 years. These are separated by warmer interglacial periods lasting around 10,000 years.

Scientists from the German UFZ and at the Russian Academy of Sciences have been looking into the last interglacial period called the Eemian which ended around 115,000 years ago and have found that that it ended with “significant climate fluctuations”. They have examined ancient lake sediments exposed by modern open-cast mining in Russia and Germany. “The short warming events observed during the transition from the last interglacial to the last glacial epoch is a naturally occurring characteristic of such transition phases.” said Dr Tatjana Boettger of the UFZ.

The Eemian ice-free period wound up with serious changes in vegetation before the glaciers surged south reaching Berlin 21,000 years ago. This Weichselian Glacial era ended around 15,000 years ago, leading to the conditions which have been seen for all of human history with the ice caps confined to Polar Regions. “Detailed studies of these phenomena are important for understanding the current controversial discussed climate trend and cast doubt on the wilder speculations of man-made global warming.” comments Dr Frank W Junge of the SAW in Leipzig
