Are grizzlies in Yellowstone National Park altering their long winter's slumber due to a changing climate? Federal wildlife biologists think so, and want to take a closer look into this possibility.

Forget what you might have heard about polar bears being the first species to gain Endangered Species Act protection due to climate change. Two species of coral lay claim to that unfortunate distinction.

Back in 1925 Glacier Bay National Monument was established, in part, to protect "a number of tidewater glaciers ... in a magnificent setting of lofty peaks ..." Well, as these photos show, those glaciers are slip-sliding away.

Climate change is global. No one country or hemisphere has a monopoly on calmer or stormier weather, on drier or wetter climates, on higher or lower lake, sea, and river levels. While here in the United States the National Park Service is trying to confront the change, on the far side of the world another country is doing what it can to protect its parks from climate change.
