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.

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.
- Chemistry
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.

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.

Surprise! These animals can help fight climate change
Some animals help fight climate change by boosting the amount of carbon dioxide that plants, algae and bacteria absorb from the atmosphere.

Many natural underground stores of freshwater are shrinking
A lot of these aquifers are quickly disappearing due to climate change and overuse. Fortunately, there is growth in some of the world’s major aquifers.

Rampaging vines are slowly strangling tropical forests
Called lianas,these vines are growing out of control. They may cause tropical forests to absorb less carbon dioxide — worsening climate change.

Scientists Say: Carbon capture
Carbon capture technology tackles climate change by stomping out carbon dioxide at the source.
- Science & Society
Scientists Say: Model
Models are representations of real-life systems or processes that we use to ask questions, make predictions and test our knowledge.
