August 24, 2012 Climate change is exaggerating the normal swings in weather. For the American Southwest, that means more intense waves of heat, drought and fire that could wipe out trees that have stood for centuries. It's already revamping the ecology of the landscape.
August 23, 2012 Huge wildfires are burning in the West — setting new records for damage this summer. These megafires are burning bigger and hotter than ever before.

July 9, 2012 Naturally polluted water from the Marcellus Shale can rise up through the natural-gas-rich rock formation to the surface. That means that water used in fracking potentially could, too. The water may be making its way up through natural fractures in the earth or old oil and gas wells.
June 18, 2012 In the latest example of plants harnessing animals to help them procreate: Spiny mice eat the sweet mignonette's fruit but a chemical cocktail the plant mixes up makes them spit out the seeds intact.
June 13, 2012 The federal government promised almost 30 years ago to find a place to bury nuclear waste from power plants. It hasn't. So 70,000 tons of waste is piling up at power plants around the country, and a federal appeals court has told the government it needs to prove the temporary solution is truly safe.
June 8, 2012 About 100 tons of marine life rode aboard the huge concrete dock that washed ashore in Oregon earlier this week. Marine biologists were shocked to see that Japanese coastal species survived the trans-Pacific trek, but they are also worried about the risk for invasive species.
May 14, 2012 Industry has ruined a lot of Pennsylvania's water. Coal mining companies hammered the state, leaving behind acidic water that turned thousands of miles of streams into dead zones. People in the state are looking for ways to make sure the fracking boom doesn't deal another blow to its water.
