An innovative collaboration between scientists is discovering how, 700 years ago, a mysterious, prehistoric culture overcame its landscape’s harsh constraints. The findings may tell a cautionary tale for today’s Southwest.
There’s more carbon locked up in the high north’s permafrost than the combined total released into the atmosphere by humans. The big melt going on right now in the Arctic could trigger a train of catastrophic events across the world.
Interior Secretary Ken Salazar has issued voluntary federal guidelines to minimize the impact of wind power facilities on wildlife by approving them in the right places. Audubon is doing its part, too.
A Canadian-based company is bluffing and bullying its way through six states so it can pump the world’s dirtiest oil through a 1,661-mile-long pipeline that crosses some of our most fragile wildlife habitats and lies inside earth’s largest underground reservoir.
Welcome to the new era of “megafires,” which rage with such intensity that no human force can put them out. Their main causes, climate change and fire suppression, are fueling a heated debate about how to stop them.
Maytag’s departure left a small Iowa town’s economy reeling. Today, however, workers are building wind machines instead of washing machines, and validating studies about the enormous potential of green-collar jobs.

Not even a tragic accident could derail two young men’s inspiring project to study one of North America’s least-understood birds. Their groundbreaking research is helping ornithologists understand how to help these birds as a warming climate alters their mountain home.
Right here in North America could lie the answer to our energy needs. But at what cost? Mining the tar sands of Alberta threatens to strip the world’s largest intact forest of its ability to hold carbon and to wipe out the breeding grounds for millions of birds.
