Abstract

Climate change has arrived in America’s National Parks. Native trees and animals are losing ground because changing temperature and weather patterns are making the availability of food, water, and shelter less certain. Fish and wildlife are being driven from their national park homes by changes that are unfolding faster than the animals’ ability to adapt. If we fail to act, some wildlife may even go extinct.

Fortunately there’s still time to protect the parks’ living legacy. If we stop contributing to global warming pollution, ensure that the parks have clean air and water, give wildlife freedom to move to new homes as the climate warms, and take other steps, America’s national parks will continue to support abundant, healthy wildlife populations.
