Human activities, such as burning fossil fuels, are warming Earth's climate. The climate crisis has widespread ramifications. Ecologists are worried that many species will become extinct because they might not be able to adapt to a climate change that's faster than most naturally occurring ones.

It's possible that some plants and animals could adapt by shifting their habitats towards Earth's poles, or towards higher elevations, to avoid the heat. Since ecosystems are varied and complex, ecologists can only find out by studying many specific cases.

A team of American ecologists explored this possibility for a species of hummingbirds native to North America's west coast, called Anna's Hummingbird. The researchers published their findings in 2022. Anna's hummingbirds live in California's lowlands, but migrate upslope into the cooler
