What happened

Peatlands are vital for tackling climate change, yet scientists still haven't found them all Gaby Clark Scientific Editor Andrew Zinin Lead Editor Push a metal corer into a peatland and you pull up something remarkable: a dark, dense, sponge-like material…

Why it matters

In some places, that peat has been building up for thousands of years.

Common ground

Peatlands are the ecosystems where this happens.
