Improved representation of ocean heat transport in newer climate models
01.03.2022, 13:17
While in most earlier climate models, the water flowing into the Nordic Seas was too cold, current models represent both the water temperature and the resulting heat transport better.
A first unified vision of ocean biodiversity
15.02.2022, 09:57
The deep-ocean floor is the least explored ecosystem on the planet. DNA collected during 15 international deep-sea expeditions reveal the regions and organisms most important for removing carbon from the surface. Tristan Cordier writes about his new study.

Improving climate model projections of carbon and heat uptake in the Antarctic Ocean
25.01.2022, 09:10
Researchers unveil a new relationship for climate models linking carbon and heat uptake with the water-column stability in the Southern Ocean.
Only modest changes in near future biological production in the Barents Sea
15.12.2021, 11:14
Global warming changes the conditions for ecosystems in the Barents Sea. A recent study found large variations between years and decades, though only modest changes on longer time scales.
A wind forecast from 10,000 years ago
07.12.2021, 16:18
Pollen can travel far through the air, allowing scientists who find them to trace the winds of the past. In South Georgia ancient pollen may reveal shifts in the westerlies.
Counting ice-transported debris using CT
15.11.2021, 13:25
With equipment normally found in hospitals, geologists can analyze material quicker. Jan Magne Cederstrøm writes about the use of CT scans in a study of debris transported by glaciers.
The North Atlantic region feels the effect of the tropical Pacific Ocean
26.10.2021, 10:13
With a new La Niña in the Pacific, colder conditions could be expected in the North Atlantic. However, in northern Europe and Russia, climate warming balances the cooling.
No influence from Arctic sea ice on mid-latitude winters
30.09.2021, 16:25
In the last decades, little sea ice in the Arctic in fall has been associated with cold winters in Europe. A new study signals little reason to prepare for frosty nights and heavy snow, despite less than normal ice in the north.
Oxygen loss in fjords, coastal areas, and open ocean systems
20.09.2021, 13:19
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.
Tracking Atlantic water
18.08.2021, 09:57
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.
Recreating Snowball Earth
29.06.2021, 09:57
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 dimension of biodiversity changes on islands
26.05.2021, 09:45
"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.
Where did the CO2 go 21 000 years ago?
12.05.2021, 13:47
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.
Prehistoric megafloods smaller than assumed
11.05.2021, 10:38
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.
Reducing emissions may halve sea level rise from melting ice
04.05.2021, 14:50
Limit global warming to 1.5°C and halve the land ice contribution to sea level this century
No quick fix for climate change
14.04.2021, 15:51
Injecting particles into the atmosphere would reduce the temperature increase. But for the world’s ecosystems there is no alternative to mitigation efforts.
Ocean heat content near tropical cyclones in the Southwest Pacific
13.04.2021, 15:30
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.
The tripole pattern of East China precipitation in the past
13.04.2021, 13:20
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.
