Cutting down boreal forest and sinking the felled trees in the depths of the Arctic Ocean could remove up to 1 billion tonnes of carbon dioxide from the atmosphere each year – but it could come at a cost to the Arctic ecosystem Cutting down swathes of boreal forest and sinking the trees into the depths of the Arctic Ocean could remove up to 1 billion tonnes of carbon dioxide from the atmosphere each year. Coniferous trees prone to wildfires could be felled and carried to the ocean by six major Arctic rivers including the Yukon and Mackenzie, where they would sink in about a year, according to a team of researchers. “There is now a forest that is sequestering lots of carbon, but now the next thing is how to store it in a way that won’t get burned,” says Ulf Büntgen at the University of Cambridge. Humanity will need to find ways to remove carbon dioxide from the atmosphere to c
