Fossil-fuelled marine heatwaves are sweeping the seafloors on both sides of the Arctic Ocean. Ten billion Bering Sea snow crabs were climate victims over a two-year period (2018 and 2019).
Bering Sea floor temps topped 4C, more than double the polar snow crabs environment. That prolonged spike in temperature depleted oxygen. It increased the energy requirement of all bottom life, which directly led to trillions of marine creatures dying over an area 7X larger than Alaska. Moreover, that manmade heat precluded life along the ocean floor from storing carbon.
