Arctic Greening

Solar geoengineering could buy humanity time against climate change—or trigger a dangerous new arms race. A first-of-its-kind simulation offered a glimpse of what happens when geopolitics takes the wheel.

Seven of 16 planetary vital signs are in their most extreme state ever recorded, and El Niño is here to make matters even worse.

While oil is known to float, new research finds that over time it can permeate even extremely deep marine habitats, with animal populations declining by as much as 80 percent.

Ancient plants reveal that the vestiges of the North American ice sheet started expanding a few thousand years ago, but that climate change caused it to reverse course.

Redwoods adapted to a cool, foggy climate. Now a new study shows they slow down photosynthesis when their environment warms.

European countries are leading the way harvesting heat that would otherwise be wasted as green death practices become more common.

A global network of detectors are reporting some of the most substantial measurements yet of neutrinos created deep underground by the radioactive elements that power our planet’s tectonic activity.

A plan to funnel the heat given off by data centers into nearby homes has run aground in Germany. Across Europe, policymakers are weighing AI ambitions against climate objectives.

Scientists can’t agree why reefs in the Red Sea have long been immune to bleaching. The answer could be the key to saving these tough corals as climate change begins taking its toll.

The cloud has baffled astronomers since its discovery in 2018. Now, a new study offers a possible cause for its appearance.

Here’s what we know about the record-setting El Niño on a record-hot planet, and the most important questions scientists are trying to answer.
