A new Science paper shows that human-caused changes to Amazonian ecosystems are hundreds to thousands of times faster than those of natural climatic and geological processes.

The circulation in the North Atlantic Ocean can dampen or enhance temperature increase and ice melt in certain decades. Researcher warns against interpreting reduced temperature increase as a sign of a slow-down in climate change.

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.

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.

The acceleration of biodiversity change began millennia ago and was often larger than the shift from the last ice age to modern temperatures, a UiB study published in Science shows.

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.

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.

As the ice was retreating at the end of the ice age, the melting was suddenly interrupted. A cold period of more than a thousand years followed.

Ocean currents have brought more heat into the northern seas after 2001. The northern extension of the Gulf Stream has warmed and probably also strengthened.

Widespread sea ice decline within 250 years unleashed abrupt climate change during the last glacial period. A new study documents that the cause of the severity of the changes resides in the ocean. 

The ocean is a questionable babysitter. Kristine Flacké Haualand takes us to the cradle of midlatitude cyclones.

You have very likely heard about the Gulf Stream. The Iceland-Faroe Slope Jet, you have never heard of. This current is the newest one on the map.

Margit Simon and her colleagues have detected anthropogenic CO2 from the 1950s and onwards in sediments from the Icelandic shelf. Here she writes about their new study.

New projections of the effect of greenhouse gas emissions on Greenland and Antarctica’s role in sea level rise, gives estimations beyond the amount that has already been set in motion by Earth’s warming climate.

It is far from the Arctic to Tibet. A new study shows how variations in sea ice may influence the transport of air pollution into the Tibetan Plateau.

A new study shows that the recent Arctic warming compares to abrupt climate change events in the distant past.

Extreme stratospheric events impact weather at the surface. New research suggest the troposphere causes the events.

The water entering the Barents Sea is not as cooled down as it used to. This has a large effect on the climate in the area and may lead to fish and other marine life migrating, shown in a Nature Climate Change study.
