Alps ice-free…6000 years ago, when CO2 was much lower than today’s levels.
Dr. Sebastian Lüning earlier today released his latest Klimaschau report, No. 6. In the first part he looks at glaciers in the Alps over the course of much the Holocene.

It turns out that Most of the Alps were ice-free 6000 years ago, glaciologists have discovered.
In his video, the German geologist presents a new paper authored by glaciologists Bohleber et al, 2020 of the Austrian Academy of Science. The Austrian-Swiss team discovered from ice cores that the 3500-meter high Weißseespitze summit was ice free 5900 years ago.
Much warmer in the early Holocene
Lüning next shows why the Alps were ice-free 6000 years ago by using a chart by Heiri et al 2015, which shows it was some 2°C warmer than today.
