Permafrost melt is a main reason for the release of the greenhouse gas methane. In which part of the world is it melting the most?

Permafrost is thawing most rapidly across the Arctic region, releasing trapped methane.

The Himalayan region holds frozen ground but is not where permafrost thaw is greatest.

The Antarctic is largely ice-covered and not the main site of thawing permafrost.

British Columbia has some permafrost but far less than the vast Arctic expanse.

Warming Arctic soils free ancient carbon as methane and carbon dioxide.

This release forms a feedback loop that can accelerate global warming.
