The world economy has run into a brick wall. Despite countless warnings in recent years about the need to address a looming hunger crisis in poor countries and a looming energy crisis worldwide, world leaders failed to think ahead. The result is a global food crisis. Wheat, corn and rice prices have more than doubled in the past two years, and oil prices have more than tripled since the start of 2004. These food-price increases combined with soaring energy costs ...

From his Cessna a mile above the southern Amazon, John Carter looks down on the destruction of the world's greatest ecological jewel. He watches men converting rain forest into cattle pastures and soybean fields with bulldozers and chains. He sees fires wiping out such gigantic swaths of jungle that scientists now debate the "savannization" of the Amazon. Brazil just announced that deforestation is on track to double this year; Carter, a Texas cowboy with all the subtlety of a chainsaw, ...

Scientists have made lots of projections over the past few years about how warming temperatures and a changing climate will affect the planet. Real-world measurements have confirmed at least some of them: sea level is clearly rising, for instance, and the ice that covers the Arctic Ocean is shrinking and thinning — in the latter case, faster than anyone had expected just a few years ago. Other measurements are a lot more difficult, though. It's reasonable to expect, ...

When I first began writing seriously about environmental issues several years ago, one thing annoyed me above all else: the refusal of many climate scientists to talk about the policy implications of their research. I'd be speaking to a researcher who had documented the rapid melting of alpine glaciers, who knew that it was chiefly due to manmade global warming — but they still refused to talk about what we might be able to do to prevent ...

Osama bin Laden once crowed to an interviewer, "Believe me, when your children and your wife become part of your struggle, life becomes very enjoyable." The late Al-Qaeda chief uttered those words before 9/11, when he was able to keep his four wives and many children living comfortably in separate houses across Afghanistan. Every few weeks or so, Bin Laden would drop in on a wife to fulfill his husbandly duties. But at the end, his rosy portrayal ...

No, Al Gore did not invent the Internet, but the former Vice President and Nobel Peace Prize winner has always has a hand in high-tech, even as he warned the world about global warming. Those two interests are intersecting with the release of a new iPad, iPhone and iPod Touch app version of his recent climate and energy book Our Choice. The app is one of the first truly multimedia e-books, with interactive graphics, video, photos with ...

Anders Dahlvig recently hit the 10-year mark as CEO of Ikea. Under his leadership, the Swedish furniture giant has nearly tripled its number of stores and employees, and committed to a broad new slate of policies on the environment. The company maintains a mixed reputation on quality, though, in the midst of an increasingly tough economic climate. In a series of recent conversations, Dahlvig spoke with TIME's Jeremy Caplan about why the tough business climate works in ...

The promise of biofuels like ethanol is that they will someday help the world grow its way out of its addiction to oil. Nine billion gallons of corn ethanol were produced in the U.S. in 2008, while countries like Brazil have already widely replaced gasoline with ethanol from sugar cane and countless start-ups are working to bring cellulosic and other second-generation biofuels to market. The reasoning is that if we use greener biofuels in place of gasoline, ...

If there were any climate-change doubters in the wine industry, it seems they are now as rare as a 1921 Chteau d'Yquem. As the third annual World Conference on Climate Change and Wine gets underway April 13-14 in Marbella, Spain, the debate seems to be settled, and a new evolution in mentalities is taking place. "I think the majority of the wine industry has acknowledged that there is a problem called climate change — the impacts are ...

California, you may have heard, is an apocalyptic mess of raging wildfires, soaring unemployment, mass foreclosures and political paralysis. It's dysfunctional. It's ungovernable. Its bond rating is barely above junk. It's so broke, it had to hand out IOUs while its leaders debated how many prisoners to release and parks to close. Nevada aired ads mocking California's business climate to lure its entrepreneurs. The media portray California as a noir fantasyland of overcrowded schools, perpetual droughts, celebrity ...
