A team of marine biologists with the U.S. National Oceanic and Atmospheric Administration's Alaska Fishery Science Center has solved the mystery of why approximately 10 billion snow crabs vanished from the Bering Sea back in 2018/2019—the water there was too warm for them.
Its a short article, but here's a summary: Snow crabs caloric needs are tied to temperature. If its too warm, it increases the amount of calories they need to survive. The most recent heat wave doubled this food demand.
Imagine if everyone in China needed double the food due to a sudden weather change.
