During the past few years, one sees from time to time news releases e.g. here about the “Green Alps”‘? from several German and Swiss scientists: Schlüchter, U Joerin, Holzhauser and Hormes in particular. The NAS panel mentioned Hormes et al 2001 in the sentence after Thompson’s organics, but paid no attention to it. It turns out to be a very interesting article, which I plan to write up.
While I was looking at this article, I stumbled across a German-language article by Schlüchter and Joerin in a popular magazine, which showed some spectacular pictures and drawings “€œ things that are unfortunately almost always absent from modern academic literature. I can do little better here than to simply show two illustrations from that article “€œ one showing a modern view of a pass in the Alps (with glacier lines of 1922 and 1856) and the other being a reconstructed view in Roman times of 2000 years ago. They identify 8 intervals of expanded forest lines (which I will discuss in connection with Hormes et al 2001).
Caption: Top – at the Susten Pass: View of Steisee, (left), Steilimi glacier (center) and the Gwaechtenhorn (left top) around 1993, with drawn-in glacier conditions as of 1856 (close of Little Ice Age) and 1922. Bottom – the same landscape at the Susten Pass, as it approximately looked from Roman time forward approx. 2000 years ago, as the Steiglet had withdrawn approximately to the height of the Tierbergli hut (2795 m). According the forest border was higher and the landscape showed a completely different picture than today.
It would have been far more interesting if the NAS panel had discussed something like this – and I’d have been interested in their opinions – as opposed to regurgitating Lonnie Thompson and it’s too bad that they didn’t analyze the issues.
