Ocean changes almost starved life of oxygen

Chemical changes in the oceans more than 800 million years ago almost destroyed the oxygen-rich atmosphere that paved the way for complex life on Earth, new research suggests.

Antarctic sea ice is key to triggering ice ages, study finds

We've known for years that Earth's climate is like a giant Rube Goldberg machine: Pull one lever, and a massive chain of events starts into motion. Yet many of the steps that drive these changes have remained shrouded in ...

Can oceans turn the tide on the climate crisis?

As we pump more greenhouse gases into the atmosphere, the world is warming at an alarming rate, with devastating consequences. While our vast oceans are helping to take the heat out of climate change, new research shows that ...

Earth warming more quickly than thought, new climate models show

Greenhouse gases thrust into the atmosphere mainly by burning fossil fuels are warming Earth's surface more quickly than previously understood, according to new climate models set to replace those used in current UN projections, ...

Geoengineering versus a volcano

Major volcanic eruptions spew ash particles into the atmosphere, which reflect some of the Sun's radiation back into space and cool the planet. But could this effect be intentionally recreated to fight climate change? A new ...

Chaos theory provides a way for determining how pollutants travel

Floating air particles following disasters and other largescale geological events can have a lasting impact on life on Earth. Volcanic ash can be projected up to the stratosphere and halt air traffic by lingering in the atmosphere ...

Longer summer dry season observed in Congo rainforest

A recently documented long-term drying trend over the Congo Basin could have important implications on the future of the world's second largest rainforest, according to a study published today in Nature Climate Change.
