To ‘green’ AI, scientists are making it less resource-hungry

Energy demands of ChatGPT and similar AI tools can threaten Earth’s climate. So researchers have begun redesigning how to run data centers and build AI.

Chemists make device to destroy planet-warming methane pollution

It can slash diffuse sources of this extremely potent greenhouse gas, such as from livestock barns and other sites.

Warmer seas trigger skyrocketing ice loss in 3 Antarctic glaciers

Destabilized by waves and vanishing sea ice, one of the glaciers lost 25 kilometers (15.5 miles) of ice in 16 months — a possible hint of worse to come.

Chemistry

Pollution power? A new device turns carbon dioxide into fuel

Scientists made a device that converts the greenhouse gas into formate. This salt can then run a fuel cell to make electricity.

Tech

Offshore wind farms could do far more than just make clean power

Offshore wind farms cost more than onshore ones. But their ability to make ‘green’ hydrogen and capture carbon dioxide could help this wind power pay off.

Ecosystems

Restoring giant underwater forests, one blade at a time

Giant kelp are at risk due to climate change and human activities. In New Zealand, a community effort is rebuilding these underwater algal forests.

Shading corals during midday heat can limit bleaching

Shading coral reefs during the sunniest part of the day may help corals survive marine heat waves.

How green is your online life?

From the manufacturing of our favorite devices to using them for social interactions, our digital lives can have a big climate impact.

Climate

Some tree leaves are finding it too hot for photosynthesis

Earth’s ongoing fever threatens to push entire forests toward this heat limit — and possible death.

Explainer: Why are so many hurricanes strengthening really fast?

This dangerous trend appears relatively new — and growing. Studies also have begun linking it to our warming world.

Climate

Hydrogen energy could help our climate — depending on its source

Hydrogen energy doesn’t emit greenhouse gases when it’s used. But how it’s produced will affect how useful it can be in slowing climate change.

Explainer: The hydrogen rainbow

Hydrogen works the same, regardless of its source. But how clean or “green” it is very much hinges on its color-coded name — which points to how it was made.
