Methane bubbling to the surface as the Arctic sea ice retreats could have catastrophic consequences for the global economy, a team of researchers argue in a new paper. To avoid the economic pain measured in tens of trillions of dollars over the coming century will “require major reductions in global emissions” of greenhouse gases, the team concludes.

The economic fallout will come from an added uptick in extreme weather, rising seas, reduced crop yields and other impacts already associated with global climate change.
