Arctic rivers face big changes with a warming climate, permafrost thaw and an accelerating water cycle − the effects will have global consequences

A new study shows how thawing permafrost and intensifying storms will change how water moves into and through Arctic rivers.

¿Qué tiene que ver el cambio climático y las tormentas de nieve que experimenta EEUU?

Los inviernos en el Noreste de EEUU se estan calentando, pero las nevadas son cada vez más intensas. ¿Cómo se puede conciliar la racha de grandes tormentas de nieve con el calentamiento del clima?

Why a warming climate can bring bigger snowstorms

Winters are getting warmer, yet Bostonians were digging out from nearly 2 feet of snow from a historic blizzard in late January. Why is the Northeast seeing more big snowstorms like this?

Will the Arctic shift from a carbon sink to a carbon source?

Global warming is changing the movement of carbon within northern ecosystems to the point where the Arctic could become a net source, rather than sink, of greenhouse gas emissions.
