On a day set aside to celebrate the Earth and the environmental movement, the Interior Department and National Park Service gave us dollars and cents.

Nearly two dozen World Heritage Sites, which have been found by the United Nations Eduational, Scientific, and Cultural Organization to offer outstanding global value for their cultural and natural resources, can be found in the United States. And the National Park Service has just made it easier to locate them.

For those of us who love our national parks and are confronted daily with media, politicians, and pundits warning us of a coming global-warming disaster, it’s only natural to ask what that warming will mean for our national parks. This is exactly what the well- known Union of Concerned Scientists discuss in their recent report, National Landmarks at Risk: How Rising Seas, Floods, and Wildfires Are Threatening the UnitedStates’Most Cherished Historic Sites.

Wondering which national parks have been able to reopen with state funding? Here's a list, and the dates the parks are to remain open...barring some resolution in Washington or more funding from the states.
