Wetlands are some of the world’s most undervalued weapons against climate change. They store huge quantities of carbon – but without better protection, many could soon be drained or paved over.

A 20-year-old experiment is testing whether filling the Arctic tundra with animals could keep carbon trapped in the ground.
Climate change is transforming the Arctic, with impacts on the rest of the planet. A geographer explains why he once doubted that human actions were causing such shifts, and what changed his mind.
The ice sheet is melting and permafrost is thawing. What’s happening in Greenland will speed up climate change across the world.
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
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.
Scientists are studying how carbon-rich permafrost known as yedoma acts much like frozen vegetables to hungry microbes – and is becoming an additional source of heat-trapping gases.
