Swiss Glaciers Expose Earlier Warm Periods
Receding glaciers in the Swiss Alps are exposing evidence of earlier warm Holocene periods. Researchers are discovering that green forests once existed under the ice and that the Alps were mostly greener than today. New findings obtained by a Swiss glaciologist cast more doubt on todays global warming hypotheses.
The following is a summary essay of the report that appeared in the Swiss news journal Die Weltwoche by Alex Reichmuth
Christian Schlüchter, Professor of Geology, and his team of researchers are studying remnants of ancient trees and peat that have been exposed by melting glaciers high in the Swiss Alps. At first sight, these pieces of wood may not look spectacular, but they are up to 10,000 years old and have a story to tell.
These tree remnants include complete tree trunks that were scraped and twisted by the massive ice sheets that once covered them. Over time these chunks of wood were transported by the glaciers partway down the Alps, and it was not exactly sure from what elevation they originated. But the wood chunks and peat prove one thing: Today, where one now only finds bare rock and gravel, and even where there is still ice, trees once grew there thousands of years ago.
