Across vast swaths of the northern hemisphere’s higher reaches, frozen ground holds billions of tonnes of carbon. As global temperatures rise, this “permafrost” land is at increasing risk of thawing out, potentially releasing its long-held carbon into the atmosphere.

Flooding and erosion resulting from damage to natural coastal defences could cost Britain £15 billion a year by 2050, a report has warned.

The Global Futures report looks at the services nature provides such as pollinating crops, protecting coasts from flooding, water supplies, timber production and fisheries.
