Climate Crisis Worsens: New Study Shows Peatlands Losing Battle Against Drought

Extended dry spell conditions significantly decrease the capacity of peat to absorb additional carbon dioxide (CO2). One-half was exposed to mild drought, with the water level roughly 5 centimeters lower than the peat itself. The other half was subjected to severe dry spell conditions; in this case, the water was twenty centimeters below the peat.

Robroek: Under severe drought conditions, nevertheless, the peat can hardly take on any more carbon.
