As the Global Tipping Points Report of 2023 was released at COP28 in Dubai, key recommendations were presented by Professor Tim Lenton.

If the sea rises one meter, will five centimeters more or less matter? That depends on where you are. Climate researchers develop methods for more precise projections of sea level rise in Northern Europe.

In a large-scale airplane campaign researchers will follow water molecules from take-off till landing.

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.

Recent observations have shown a reduction of water masses travelling southwards in the deep ocean.

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. 

"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.

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

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.

Sea level variations in Northern Europe are influenced by winds high above the Atlantic, new study shows. In the western part of the North Sea, the wind direction is more important than the wind speed.

Scientists have revealed how life populating the shadowy ocean below the surface evolved as Earth’s climate cooled over millions of years. 

A new global ice sheet reconstruction for the past 80 000 years in Nature Communications.

Though sea-level contributions may be the same, increasing the spatial resolution in models provides more details about outlet glaciers. Heiko Goelzer writes about a new study of the Greenland ice sheet. 

Stephen Outten and Ingjald Pilskog run the Bjerknes Centre for Climate Research podcast and recently talked to Igor Ezau about heatwaves and their dangers.

A new project will help crops and reduce flood risk for region of 365 million people.

A new study published in Nature Geoscience shows that temperature in the Southern Ocean was more tightly linked to the extent of Antarctic glaciation during past greenhouse climates than previously thought.
