Alaska’s beavers are profiting from climate change, and spreading rapidly. In just a few years’ time, they have not only expanded into many tundra regions where they’d never been seen before; they’re also building more and more dams in their new homes, creating a host of new water bodies. This could accelerate the thawing of the permafrost soils, and therefore intensify climate change, as an International American-German research team reports in the journal Environmental Research Letters.
