A new method to remove CO2 from the atmosphere involves molecules that become acidic when exposed to light.

Capturing and storing carbon dioxide in recycled concrete aggregate or geological reservoirs is feasible and has a positive carbon footprint.

Massive volcanic eruptions over the past 260 million years caused lethal climate change that led to mass extinctions, researchers say.

Savannas and grasslands in drier climates store more carbon than we knew, slowing the rate of climate change, researchers say.

A new strategy could lead to more efficient methods for converting carbon dioxide into valuable chemicals and fuels.

New technology could lower the cost of capturing carbon dioxide from all types of emissions, researchers report.

A new study uncovered evidence that mosses have the potential to store a massive amount of carbon in the soil beneath them.

In a worst-case scenario, oceans will hit a tipping point in their ability to soak up emissions by 2100, researchers report.

A new engineered wood could cut both emissions and construction costs. It's also stronger than normal, untreated wood, researchers say.

"We were surprised at how significant a role dust accumulation played in switching coral reefs from a CO2 source to a CO2 sink."
