could disappear by the year 2500, unless greenhouse gas emissions are dramatically reduced.
Even in the best-case scenarios
two-thirds of this landscape — defined by its short growing season and cover of grasses, moss, shrubs and lichens

permafrost cover melts away, it could release vast quantities of stored greenhouse gases

The loss of the tundra

Warming in the Arctic has
advanced rapidly in recent decades, about twice as fast as warming in the rest of the globe.
