The Race to Rebuild the World’s Coral Reefs

In the late 1990s, Vaughan learned that Aqua Life, an ornamental-fish-breeding operation on a small island in the Bahamas, was shutting down. Harbor Branch made a bid to buy what was left, and a month later, 22,000 orange and...

Technology Can Fix the Climate Mess—but Not Without Help

Advances in battery technology, for instance, have driven down electric vehicle prices, leading to increased adoption among drivers. The costs of lithium-ion batteries, and of wind and solar power, dropped by up to 85 percent between 2010 and 2019....

A Wave of Startups Is Tackling Cow Burps and Other Climate Issues

“There’s a real belief that we can move at a pace that’s more similar to a software company,” says Brown, who worked at a data startup before starting Alga Biosciences. (His cofounders are both chemists.) Researchers have only just...

Companies May Soon Have to Reveal a Hidden Risk: Carbon Emissions

In 2020, Microsoft decided it wanted to be “carbon negative” by the end of the decade—to remove more greenhouse gases from the atmosphere than it produces. That first year, it started on the right foot; emissions fell 6 percent....

A Bold Idea to Stall the Climate Crisis—by Building Better Trees

Now a Californian startup has taken the same approach, but this time with poplar trees. In a non-peer-reviewed preprint first posted on February 19, scientists at Living Carbon claimed that by inserting new genes into poplar trees, they can...

Astronomers Tally the Growing Carbon Footprint of Space Science

For generations, astronomers have spent lonely evenings at remote mountaintop observatories peering at stars and planets as they whirl overhead. Today’s astronomy, however, is being conducted on a more massive scale: Huge arrays of receivers continually feed signals into...

Underwater Permafrost Is a Big, Gassy Wild Card for the Climate

The result is the worrisome image shown above—a massive sinkhole indicating that the subsea permafrost has thawed and collapsed. This sinkhole is a giant among dozens of pockmarks the researchers found on the seafloor. Scientists have already documented this...

Climate Change Is Disrupting the Global Supply Chain Too

Supply chains are, in essence, strings of potential bottlenecks. Each stopping point is a node in a tree-like system that conveys raw materials from the system’s farthest tendrils to sub-assemblers along its roots to manufacturers, who are the system’s...

The Nuclear Reactors of the Future Have a Russia Problem

Say you want to make nuclear fuel: Take some uranium, and with molecular wizardry, transform this heavy metallic element into a gas. Then put it in a centrifuge and whirl it around in a radioactive tornado, until the lightest...

Why You (and the Planet) Really Need a Heat Pump

“The easiest way to think about this is like your backyard is a battery,” says Ryan Dougherty, president of the Geothermal Exchange Organization, a trade association that advocates for geothermal heat pumps. “You can draw off that thermal battery...
