Under a White Sky

In its broad outlines, Dansgaard’s reading of the Camp Century core confirmed what was already known about climate history. The most recent ice age, known in the United States as the Wisconsin, began roughly a hundred and ten thousand years ago. During the Wisconsin, ice sheets spread over the northern hemisphere until they covered Scandinavia, Can

In the 1960s, climate- and weather-control proposals were all the rage, both in the United States and the USSR. Project Stormfury, a collaboration between the U.S. Navy and the Weather Bureau, targeted hurricanes. These, it was believed, could be weakened by sending aircraft to seed the clouds around the eyewall with silver iodide.

The number of species that can be found on a healthy patch of reef is probably greater than can be encountered in a similar amount of space anywhere else on earth, including the Amazon rainforest. Researchers once picked apart a single coral colony and counted more than eight thousand burrowing creatures belonging to more than two hundred species.

GBIRd wanted Thomas’s help designing a very particular kind of mouse drive—a so-called “suppression drive.” A suppression drive is designed to defeat natural selection entirely. Its purpose is to spread a trait so deleterious that it can wipe out a population. Researchers in Britain have already engineered a suppression drive for Anopheles gambiae

CPRA’s “bold” scheme for saving Plaquemines is to rehabilitate the crevasse for a post-crevasse age. The agency’s master plan calls for punching eight giant holes through the levees on the Mississippi and two more through those on its main distributary, the Atchafalaya. The openings will be gated and channelized, and the channels will themselves be

Albert Einstein: “We cannot solve our problems with the same thinking we used when we created them.”

How were two million people going to live in a region that was sinking into oblivion? The losses were particularly acute, he noted, in their own backyard. The area around Plaquemines had already shrunk by some seven hundred square miles. “We’re in an uphill battle against sea-level rise and subsidence,” Barth said. CPRA would continue to drill and

Cane toads are not just disturbingly large; from a human perspective, they’re also ugly, with bony heads and what looks like a leering expression. The trait that makes them truly “hated,” though, is that they’re toxic. When an adult is bitten or feels threatened, it releases a milky goo that swims with heart-stopping compounds. Dogs often suffer ca
