Arctic sea ice thinning twice as fast as thought, study finds

Less ice means more global heating, a vicious cycle that also leaves the region open to new oil extraction

Sea ice across much of the Arctic is thinning twice as fast as previously thought, researchers have found.

Arctic ice is melting as the climate crisis drives up temperatures, resulting in a vicious circle in which more dark water is exposed to the sun's heat, leading to even more heating of the planet.
