There are fewer and fewer humpback whales in the North Pacific. The population of the largest marine mammals fell by 7,000 individuals between 2012 and 2021.

Rising temperatures are disrupting the entire marine ecosystem and whales are no longer finding enough food. In 2022, another study showed that increasing ocean temperatures also had the effect of chasing humpback whale from their traditional breeding grounds. The state of health of the entire ocean is worrying, according to scientists: climate change is the third cause of the collapse of life.
