ESTES PARK, Colo.—Global warming is threatening America’s national parks. But there is no consensus on how to prevent the harm.
Arizona Republican Sen. John McCain and Democratic Sen. Mark Udall of Colorado toured Rocky Mountain National Park Monday. After the tour, the two senators heard testimony from parks officials and scientists about how global warming is harming the park system.
Glacier National Park, for example, is losing its glaciers, while low-lying coastal parkland is in danger of going underwater.
Both McCain and Udall said global warming is a grave global threat. But in the hearing, neither senator mentioned a sweeping climate change bill awaiting consideration in the Senate when lawmakers return next month.
