By 2050, sea ice at the North Pole could be gone, researchers say. But how long the disappearance lasts is up to us.

Online panel discussion hosted by MIT explores best practices for mitigating climate-related risk.

201 million year ago, climate change wiped out nearly half of the species on Earth. New research shows volcanic CO2 emissions played a direct role.

Ancient micrometeorites may have run into CO2 on their way to Earth's surface, which gives researchers a clearer view of the early Earth's atmosphere.

A new method turns just about any kind of carbon-based trash, from banana peels to coffee grounds, into "flash graphene" to make building materials greener.

An artificial photosynthesis panel could use sunlight and water to convert carbon dioxide from smokestacks into usable "green methane."

Substituting lumber for materials such as cement and steel could cut building emissions and costs.

Recommendations could help companies deliver more useful disclosures to investors on risks they face due to climate change.

Carbon capture technologies could actually produce more carbon dioxide than they suck up. Focusing on renewables is a better solution, researchers say.

The next time a river overflows its banks, don't just blame the rain. New research identifies another culprit: Leafy plants.
