Protesters dressed as swamp creatures kayaked down a river while others marched along a bike path, past private tennis courts and swanky swimming pools outside the hotel where governors met with Interior Secretary David Bernhardt.

“My shirt says keep your oily hands off of Colorado's public lands,” says Chelsea Stencel, who was among the protesters. “David Bernhardt, the ultimate swamp monster.”

This year, NPR held its first Student Podcast Challenge — a podcast contest for students in grades 5 through 12. As we listened to the almost 6,000 entries, we smiled, laughed, and even cried.

Seventeen of the world's largest automakers have asked the White House and the state of California to restart talks and come up with one set of greenhouse gas standards for cars.

Oregon is on track to become the second U.S. state to pass an economywide cap-and-trade system to regulate greenhouse gas emissions. But while emulating the first such program (in California), Oregon also hopes to avoid repeating its mistakes.

Oregon's plan, like California's, would set a cap on greenhouse gas emissions that would come down over time. It would also create a market for companies to buy and trade a limited number of pollution permits. Ultimately, it aims to reduce emissions to 80% below 1990 levels by 2050.
