In this week’s Science, researchers led by Michael Worobey of the University of Arizona and Preston Marx of the Tulane National Primate Research Center looked at the history of simian immunodeficiency virus (SIV)—the primate precursor to HIV—and found that the disease may be thousands of years older than scientists originally …

In what was possibly the most anticipated intersection between two shafts in U.S. history, the government announced late Thursday that BP’s relief well had finally connected with the company’s original blown well. That will allow BP to go ahead and place a final cement seal on the original well—finally, truly, really killing it. “The …

Wild tigers are dying. There’s no other word for it. Their numbers have declined in the wild from perhaps 100,000 at the beginning of the 20th century, to more than 10,000 in the 1980s to less than 3,500 today. Their habitat in India, Russia, China and Southeast Asia has been carved up, their prey has been taken away from them and tigers …

If you’re curious about how the endgame of the oil spill is going—it’s still ending—check out a piece I had over the weekend on the Time.com mainpage. Now I’m beginning to think hockey season could get underway before the relief well is finally completed.

When we think about the climate, we think about the atmosphere. Changes in the atmosphere—winds, clouds, precipitation, even thunderstorms—seem to give us weather, and it’s the accumulation of carbon and other greenhouse gases in the atmosphere that is gradually warming the planet. But the atmosphere is just one part of the climate …

Back in 1979—when the economy was suffering and the U.S. was facing a serious energy crisis, a situation in no way similar to what’s happening now—President Jimmy Carter installed solar panels on the roof of the White House. It was a symbol of Carter’s push to get the U.S. to face up to its energy problems, beginning with the most …

Over the past few weeks I’ve been immersed in the details of marine protected areas (MPAs) as I prepare a TIME story on the oceanographer Sylvia Earle and her crusade to defend the endangered oceans. Much of that focus has been on the Sargasso Sea in the Atlantic Ocean, where Earle and I visited last week. But as promising as the …

A little good news/bad news on the climate and energy front. In the Sept. 10 Science, Steven Davis and Ken Caldeira of Stanford University have a study that estimates what future carbon emissions—and consequent global warming—would be from existing energy and transportation infrastructure. (In other words, what would happen if we …

It’s one of the most pressing questions facing climate scientists today: how vulnerable are the vast ice caps on Greenland and Antarctica to rising temperatures? An unfathomable amount of ice is stored on those two land masses, and as that ice melts and flows into the oceans, global sea levels rise—if all the ice on Greenland …

Say this about Marshall Burke and Halvard Buhaug—they know how to title their papers. Late last year Burke, an economist at the University of California-Berkeley, co-authored a paper in the Proceedings of the National Academy of Sciences (PNAS) titled “Warming increases the risk of civil war in Africa,” which sums up the argument …
