Study: Arctic battling climate change and beavers

Cosmos discusses how the Arctic is battling climate change and beavers. It’s easier to get around, so they are.

Beavers are running amok in the Arctic, taking advantage of climate change and likely exacerbating its impact.

Studies show they are now able to move into many tundra regions where they’ve never been seen before, and once there are building dams and creating new water bodies.

This is changing the landscape and could accelerate the thawing of the permafrost soils, releasing massive quantities of greenhouse gases, according to research by a US-German team reported in the journal Environmental Research Letters.
