ClimateArctic Sea could be ice-free by 2050
Everyone contributes to the melting of Arctic sea ice, and all are in danger of making summer ice disappear there completely by 2050, a new study finds.

ClimateScientists Say: Albedo
To measure how much light reflects off an object, scientists measure its albedo.

ChemistryOxygen-rich air emerged super early, new data show
Scientists had thought animals were slow to emerge because they would have needed oxygen-rich air to breathe. A new study finds that plentiful oxygen may have developed early. So animals may have been late on the scene for another reason.

ChemistryParticles in air help fatten clouds’ water droplets
Making their own clouds has shown scientists how the fattest water droplets form. Understanding this could lead to better forecasts of climate change.

ClimateConcerns about Earth’s fever
Burning fossil fuels is causing the planet to heat up, causing weather patterns to change, sea levels to rise and diseases to spread.

ClimateExplainer: How scientists know Earth is warming
Scientists can calculate global temperatures, both present and past. Their findings show that the planet is rapidly heating up.

ClimatePicture This: Biggest hurricane in the West
The hurricane that’s storming into western Mexico has had higher sustained winds than any seen in the Western Hemisphere. It’s also got the lowest atmospheric pressure, making it a monster storm.

ClimateWarming’s role in extreme weather
Extremes in temperature and precipitation will be more common as global temperatures rise. Human-led climate change is largely to blame, a new study finds.

ClimateArctic warming bolsters summer heat
Rapid warming in the Arctic is sapping summer storms of their power to cool. That worsens heat waves across the Northern Hemisphere.
