Climate change is worsening the planet’s biodiversity crises, making environments more deadly for thousands of species and accelerating the precipitous decline in the number of plants and animals on Earth, according to an international organization that tracks species health.

Species of salmon and turtles are among those facing a decline as the planet warms.

Atlantic salmon isn’t yet threatened with extinction, but its population dropped by nearly a quarter from 2006 to 2020, the International Union for Conservation of Nature, which tracks biodiversity around the globe, said on Monday. It’s now considered near threatened. They live in fewer places and face human-created hazards like dams and water pollution. Climate change is making it harder for the fish to find food and easier for alien species to compete, according to the group. Although there are some signs of hope: their numbers ticked up in Maine this past year.
