National Parks Wrestle with Warming

As the world warms, officials at the National Park Service are starting to sweat: No glaciers at Glacier, no Joshua trees at Joshua Tree. These are part of the long-range forecast for the national parks.

Last month, in a post from Glacier National Park, I noted that Park Service director Jon Jarvis was not in a mood to mince words, calling climate change “the greatest threat to the integrity of the national park system that we’ve ever faced.”

That assertion was underscored last week in a new report on potential impacts to the parks from climate change. The collaboration by the Natural Resources Defense Council and the Rocky Mountain Climate Organization, attempted to zoom in on specific parks and projected changes ahead for ten national parks in California, as well as impacts on the state’s economy.

Some conclusions under a “medium-to-high” emissions scenario, toward the end of this century: Higher temperatures in Joshua Tree National Park would mean the end of, well, Joshua trees in the park. Muir Woods could be as warm, on average, as San Diego has been historically, making it less hospitable to the park’s legendary coast redwoods. Death Valley, already the hottest spot on the continent, could become virtually uninhabitable during the summer, as average temperatures rise by more than eight degrees, Fahrenheit, over average readings from 1961 to 1990.

Parks Chief: No “Free Ride” for Renewables

Renewable energy developers will get no special treatment in the National Parks, according to National Park Service Director Jon Jarvis.

Jarvis made the comment yesterday while touring Glacier National Park in Montana, with members of the Society of Environmental Journalists. “Renewables do not get a free ride,” said Jarvis, when asked about how the parks would treat development of renewable energy sources on park property.

Using the backdrop of Glacier National Park, where the remaining 25 glaciers (out of an estimated 150) are expected to disappear by 2030, Jarvis called climate change the most serious threat ever posed to the integrity of the park system. Continue reading
