Arctic lakes, when life stimulates methane

Mirjana Binggeli

As global warming profoundly transforms Arctic ecosystems, a new study reveals that lakes at high latitudes may be releasing more methane than previously thought. This greenhouse gas, far more potent than CO₂, is produced in the sediments of lakes that have become more biologically productive. A worrying dynamic, revealing new climate feedback loops.

Climate change reduces the ability of Arctic fjords to store carbon

An ambitious research project is surveying 16 glaciers to determine if increased levels of heavy metals in Arctic animals are related to glacial retreat.

Should sea ice be considered sovereign territory of the Inuit?

International law does not consider Inuit spatial values and forces ‘sovereignty’ onto a people who does not believe in it, a new PhD project argues.
