Climate change: why we can’t rely on regrowing coastal habitats to offset carbon emissions

We are researchers who study how marine life, chemistry and the climate interact, and after examining the processes by which coastal habitats draw down (and release) planet-warming gases, we’re not convinced. Whether the climate benefits from restoring these habitats – by planting mangrove trees, for example – is far from certain, and there’s a real risk that the scale at which they can mitigate emissions has been massively oversold[...]
