Human-induced borealization leads to the collapse of Bering Sea snow crab
摘要
The abrupt collapse of the Bering Sea snow crab stock can be explained by rapid borealization that is >98% likely to have been human induced. Strongly boreal conditions are ~200 times more likely now (at 1.0–1.5 °C of warming) than in the pre-industrial climate, while strongly Arctic conditions are now expected in only 8% of years. Stakeholders should accelerate adaptation planning for the complete loss of Arctic characteristics in traditional fishing grounds.
