Under a White Sky

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

According to a recent study by a team of German scientists, to remove a billion tons of CO2 through “enhanced weathering,” approximately three billion tons of basalt would have to be mined, crushed, and transported. “While this is a very large amount” of rock to mine, grind, and ship, the authors noted, it is…

According to a second, more widely held view, the switchover only really started in the late-eighteenth century, after the Scottish engineer James Watt designed a new kind of steam engine. Watt’s engine, it’s often said, anachronistically, “kick-started” the Industrial Revolution. As water power gave way to steam power, CO2 emissions began to rise,

As with temperatures, sea levels have in the past varied dramatically. At the end of the Wisconsin, as the great ice sheets were breaking up, there were periods when they rose at the astonishing rate of a foot a decade. (It’s been proposed that one of these “meltwater pulses” inspired the account of the deluge in Genesis.) Obviously, our ancestors

One way to gloss the Camp Century story is as another Anthropocene allegory. Man sets out to “conquer his environment.” He congratulates himself for his resourcefulness and derring-do, only to find the walls closing in. Drive out nature with a snowblower, yet she will always hurry back.

Andy Parker is the project director for the Solar Radiation Management Governance Initiative, which works to expand the “global conversation” around geoengineering. His preferred drug analogy for the technology is chemotherapy. No one in his right mind would undergo chemotherapy were better options available. “We live in a world,” he has said, “whe

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

According to the standard version of genetics that kids learn in school, inheritance is a roll of the dice. Let’s say a person (or a toad) has received one version of a gene from his mother—call it A—and a rival version of this gene—A1—from his father. Then any child of his will have even odds of inheriting an A or an A1, and so on. With each new g

Much of Plaquemines lies below sea level—six feet under, people sometimes say. This arrangement is made possible by levees—four sets of them. Two run along the river, one on each bank. Another two—known as “back levees”—run between the parish and the Gulf, to prevent the sea from rolling in. The levees, which keep water out, also keep water in. Whe
