It’s the front line of climate change and could hold the key to predicting global sea level rise, but what goes on at the underwater face of Greenland’s glaciers is a mystery to science.

New insight into how our early ancestors dealt with major shifts in climate is revealed in research by an international team, led by Professor Rick Schulting from Oxford University’s School of Archaeology.

An international team including researchers from the University of Bern and the University of Geneva as well as the National Centre of Competence in Research (NCCR) PlanetS analyzed the atmosphere of one of the most extreme known planets in great detail. 

To get through a long winter without food, hibernating animals — like the 13-lined ground squirrel — can slow their metabolism by as much as 99 percent, but they still need important nutrients like proteins to maintain muscles while they hibernate.
