Trees may be even bigger climate heroes than we thought
These plants absorb methane, a potent greenhouse gas, in addition to carbon dioxide. Methane’s uptake is likely thanks to microbes living in tree bark.

An ancient log shows how burying wood can fight climate change
A blanket of clay soil helped the wood hold onto the carbon it had absorbed — for thousands of years.

Surprise! The jet stream can trigger cloud formation
Most cloud-seeding particles may come from a newly discovered mechanism — stratospheric intrusion.

Let’s learn about how much climate change is to blame for extreme weather
Scientists can find out whether a natural disaster was more frequent or severe due to human-caused climate change. Here’s how.
- Tech
New system uses evaporation to greatly cool artificial turf
It relies on rainwater that gets stored below a field of plastic "grass." The design also limits how much rain — and pollution — will run off artificial turf.
- Climate
Stashing more CO2 in the ocean could slow climate change
More research is needed on ways to safely remove some CO2 from the water to make room for more — such as by seaweed farming and iron fertilization.
- Climate
Microbes in the Arctic may be releasing more climate-warming gases
Mini greenhouses in the wild show how the tiny organisms lurking underground in a ‘sleepy biome’ could play a big role in climate change.

Climate change is changing how scientists measure time
Polar ice sheets are melting faster. This is slowing Earth’s spin, which changes how we sync our clocks to tell time.

Scientists Say: Methane
Used to cook food and heat homes, this potent greenhouse gas accounts for 30 percent of the warming of our climate.

Gene editing may help rice better withstand climate change
Three genes may limit the ability of rice to handle dry or salty conditions. A Regeneron ISEF finalist shows that CRISPR could target and change them.

New tool maps where U.S. heat can pose threats to your health
The daily updated HeatRisk maps use color coding to show where the health threat from heat is highest. The website also offers tips for staying safe.
- Oceans
The seas’ record-breaking hot streak may bring unwelcome changes
Off-the-charts warming could fire up more hurricanes, intensify coral bleaching and accelerate the melting of Antarctic sea ice.
