Scientists propose a new mechanism by which oxygen may have first built up in the atmosphere
For the first 2 billion years of Earth's history, there was barely any oxygen in the air. While some microbes were photosynthesizing by the latter part of this period, oxygen had not yet accumulated at levels that would impact ...

Arctic permafrost thaw plays greater role in climate change than previously estimated
Abrupt thawing of permafrost will double previous estimates of potential carbon emissions from permafrost thaw in the Arctic, and is already rapidly changing the landscape and ecology of the circumpolar north, a new CU Boulder-led ...

The Greenland Ice Sheet is close to a melting point of no return, says new study
The Greenland Ice Sheet covers 1.7 million square kilometers (660,200 square miles) in the Arctic. If it melts entirely, global sea level would rise about 7 meters (23 feet), but scientists aren't sure how quickly the ice ...

North Atlantic volcanic activity was a major driver of climate change 56 million years ago, study finds
The Paleocene–Eocene Thermal Maximum (PETM) is a period of global warming that occurred ~56 million years ago, lasting approximately 200,000 years, when the Earth experienced global surface temperature elevations of ~5°C.
Scientists warn that many dangerous feedback loops make climate action more urgent
A new report written by an international team of researchers, including scientists from Oregon State University (OSU), warns of many risky climate feedback loops and the need for action in both research and policy. Published ...

Massive release of methane gas from the seafloor discovered for the first time in the Southern Hemisphere
Gas hydrate is an ice-like substance formed by water and methane at depths of several hundred meters at the bottom of our oceans at high pressure and low temperatures. Methane is a potent greenhouse gas, roughly 25 times ...
