Oxygen depletion is affecting the ecology in the open ocean as well as near the coast. Anne Gro Vea Salvenes and Elin Darelius write about a recent study aiming to learn more about deoxygenation and its impact. 

Have you ever wanted to go back in time? It is not so easy in the real world, but in the model world anything is possible.

Earth has been a snowball. In a new study, Heiko Goelzer and colleagues have used an Earth system model to study the transitions between a glaciated and a non-glaciated Earth, around 700 million years ago.

"The human footprint is everywhere, even on remote islands", John Birks writes about a new study of past ecology. All around the world, human arrival on islands rapidly affected the local biodiversity.

During the Last Glacial Maxium the atmosphere contained less than half as much CO2 as today. New study finds that both the biological carbon cycling and the ocean circulation were different. 

Mighty floods have carved out deep canyons on Earth. New research suggests this required less power than previously believed. Collecting such data, however, may be demanding. 

Limit global warming to 1.5°C and halve the land ice contribution to sea level this century

Injecting particles into the atmosphere would reduce the temperature increase. But for the world’s ecosystems there is no alternative to mitigation efforts.

The strongest cyclone ever recorded in the Southern Hemisphere reached its peak just as it struck Fiji in 2016. A new study looks at the role of the ocean directly underneath the cyclone.

Rainfall patterns in China over the past half a million years may have been more like the present than previously thought. Gaowen Dai writes about his new study.
