Park Service Centennial Spotlights Public Lands Disputes

While the 100-year old National Parks Service still enjoys widespread public support, conservative attacks put the future of public lands in jeopardy.

The prices of Yosemite National Park souvenirs have been slashed in half, and road signs directing visitors to iconic attractions have been switched. The changes took place at midnight Monday amid a bitter legal dispute between government officials and Delaware North, which operated many of the popular attractions from 1993 until Monday when competitor Aramark took over. H aving lost the $2 billion contract to run the concessions at Yosemite National Park, a food service, lodging, and retail company called Delaware North has left the park and taken with it the names of several iconic landmarks—the corporate equivalent of taking all of the marbles after losing the game. Beginning in 2002, Delaware North began trademarking many...

Where the Wild Things Are

P icture a perfect Southwestern day: The air as clear as gin, the bright blue sky marked only by a few stray clouds. In this spot, the waters of the Colorado River are placid, cool green, with none of the muddy brown foam found in the rapids that, over millennia, have carved out the Grand Canyon. Redwall limestone cliffs stretch high above. They’re streaked with desert varnish—the stain left by manganese seeps—and lightly colored with the aquamarine of lichen. Eons of the planet’s history are visible from here, whole epochs rendered in the span of a few thousand vertical feet. It’s an awesome sight. Then I move my mouse over the river surface and click on a small circle of white in the water. The scene swirls in fast-forward, and I continue my trip downriver. I’ve never rafted the Colorado River through the bottom of the Grand Canyon. My “experience” through that wonder of the world came courtesy of Google Treks, the information company’s effort to extend its popular Street View...

Is the CIA on Its Way to Hacking the Sky?

Human manipulation of the climate might be the quickest way to combat global warming. It's also the most frightening.

T he news seemed tailor-made to drive conspiracy theorists and members of the tinfoil hat club into a frenzy. In July, the National Academy of Sciences confirmed that the CIA is helping to underwrite a yearlong study examining atmospheric geoengineering—deliberate, planetary-scale manipulation of the climate to counteract global warming. As reporters took jabs at the idea of “spooks” seeking to “control the weather,” the National Academy of Sciences tried to brush away concerns. “We are not producing anything, building anything, or deploying anything. It’s more of a state-of-the-science review,” an academy spokesperson told me, noting that NASA and the National Oceanic and Atmospheric Administration (NOAA) are also helping to pay for the study. Still, the CIA’s interest in geoengineering marks a turning point in the simmering debate about the controversial technology: More and more people are starting to take the once-laughable idea seriously. Both supporters and skeptics of...

It's Not Easy Being Green

The proximate cause of the split was the revelation that between 2007 and 2010 the nation’s oldest environmental organization had clandestinely accepted $26 million from individuals or subsidiaries associated with Chesapeake Energy, a major gas firm that has been at the forefront of the fracking boom. “The largest, most venerable environmental organization in the United States secretly aligned with the very company that seeks to occupy our land, turn it inside out, blow it apart, fill it with poison,” Steingraber wrote. “It was as if, on the eve of D-day, the anti-Fascist partisans had discovered that Churchill was...

A fight against planned coal-export terminals in the Pacific Northwest is becoming the next big climate battle.

Nestled between the glacier-tipped peak of Mount Baker and the rugged coastline of the Puget Sound—the “Salish Sea,” as locals prefer to call it—the area is a magnet for hikers, climbers, and kayakers. The town boasts a vibrant local-food scene, with two summer farmers markets and a pair of organic grocery stores. The City of Bellingham and the surrounding Whatcom County government get 100 percent of their electricity from renewable sources, a practice that earned both recognition from the Environmental Protection Agency’s (EPA) Green Power Leadership program. The Natural Resources Defense Council has dubbed Bellingham one of its “Smarter Cities” for the town’s commitment to reducing its ecological footprint. So it’s no surprise that many Bellingham residents are against plans to make the area home to one of the country’s...
