'Collective problem needs collective solution: Global warming projected to increase well beyond 2°'

Arctic peatlands are expanding as the climate warms, new research showed Thursday, a change that could slow global warming in the near term but have the opposite effect in future. Peatlands are the largest terrestrial store of carbon, locking away twice as much heat-trapping CO2 from the atmosphere in their waterlogged soils as all the world's forests. For in-depth analysis and a deeper perspective, FRANCE 24's Alison Sargent welcomes Prof. Joeri Rogelj, Director of Research at the Grantham Institute and Professor of Climate Science & Policy at the Centre for Environmental Policy at Imperial College London.
