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.

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.

Engineers cook up a new way to tackle CO₂: Make baking soda

Engineers have found a material that can collect carbon dioxide from the air. When later mixed with water, it forms baking soda that can be shed in the sea.

Materials Science

A new hydrogel could help pull drinking water from the air

The salty gel absorbs more water from the air than similar gels, even in desert climates. This could provide clean water for drinking or farming.

Animals

Adult corals have been frozen and revived for the first time

Living corals could be frozen for safekeeping. Scientists could later revive them to restore reef ecosystems that are withering in warming seas.

Ecosystems

The Amazon is in trouble. Here’s why — and why it matters

Challenges from human-caused climate change, deforestation and degradation leave the fate of this vast forest uncertain.

Tech

With tech, farms can double up to produce both food and power

Agrivoltaics merges agriculture with photovoltaic panels, which generate electricity from sunlight. The combo produces clean energy and edible crops.

Agriculture

Crops are being engineered to thrive in our changing climate

Plants are already the best carbon catchers on Earth. New research could make them even better.

Let’s learn about why summer 2023 was so hot

Human-caused climate change has played a big role in this summer’s historic heat.

Oceans

Summer 2023 is when the ocean first turned ‘hot tub’ hot

Unfortunately, scientists worry that this atypical sea warming may actually be the beginning of an unwelcome new ‘normal.’
