Arctic ice melt slower thanks to ozone protections
Measures adopted in 1987 to protect the ozone layer have pushed the first ice-free summer in the Arctic back by up to 15 years.
Ways to reduce the footprint of polar research
Reducing the carbon footprint of Antarctic research could be achieved by reducing the speed of ships and international cooperation on logistics.
Pacifique to continue Arctic circumnavigation
An insurance dispute forced the postponement of last years leg, but the organisers have new ship that will allow the scientific and artistic voyage to go on
Racing yachts to measure Southern Ocean CO2
With their keels in the water and the wind in their sails, IMOCA boats could be the missing pieces in the counting of carbon dioxide molecules passing from the atmosphere to the sea and vice versa
How sea ice in the Arctic and Antarctic responds to climate change
Antarctic sea ice is not nearly as responsive to global warming as Arctic sea ice
Ice loss from Greenland and Antarctica hits new record
Ice loss from Greenland and Antarctica has increased five-fold since the 1990s, and now accounts for a quarter of sea-level rise, according to the European Space Agency
Fog, not sea ice, slow Arctic shipping’s growth
Ships are saving time and money by sailing though the Arctic, but increasingly frequent fog due to sea-ice loss is slowing its progress.
Trio of heatwaves added month to Greenland melt season
Greenland experienced its warmest and wettest September in recorded weather history in 2022, a European Union report published in April finds.
Ice-age Greenland unimpressed by massive iceberg calving
Antarctica warmed and the rest of the world also felt the effects of massive calving events during the last ice age, only Greenland remained unaffected.
Northward retreat of Arctic fish communities
When we look at the fish larvae drifting in the currents of the Chukchi Sea, the purely arctic species give way to species from the Pacific.
Ice Memory Foundation preserves “climate memory” of Svalbard
In April, an international research team “rescued” about 300 years of climate history from a glacier on Svalbard.
Ice sheets can retreat 600 meters per day
Much faster than previously thought, ice sheets can collapse and contribute to sea level rise.
Underwater methane emission in the Arctic
While we are struggling to reduce our greenhouse gas emissions, Norwegian scientists have just discovered a new natural source of methane that diffuses from the Arctic Ocean’s subsoil.
Antarctic deep-sea currents headed for collapse
According to Australian researchers, the deep-sea circulation could be on the verge of collapse with significant consequences for marine ecosystems and the global climate.
Official CH-visit of Greenland on natural disasters and research
A high-level delegation from Greenland visits Switzerland to deepen cooperation in natural disaster response and research.
When -37 degrees Celsius is considered heat
For days, the thermometers at the Amundsen-Scott station at the South Pole have been showing temperatures far above normal and there is already talk of a heat wave
Early warning signs of ice shelf collapse
Frequent, smaller breakoffs and an increase in flow velocity were signs of Larsen-B collapse, according to a new study.
The Arctic will resemble the North Atlantic sooner than expected
Climate scientists point to the deficit in understanding climate drift.
Antarctic sea ice biota and their changing habitat
Ice algae, krill, copepods, and fish are already experiencing changes in their habitat in the sea ice. A study now clarifies how they respond.
Stronger El Niño could lead to irreversible melting in Antarctica
The Pacific phenomenon El Niño could cause Antarctic ice shelves and ice sheets to melt irretrievably, while sea ice remains longer.
View beneath Thwaites glacier reveals more about its melting
The Thwaites Ice Shelf is melting from below much more slowly than previously thought, but not everywhere – melting is faster in crevasses.
When La Niña melts the ice
El Niño and La Niña climate phenomena influence ice melt in the Barents and Kara Seas.
“Anti-greenhouse gas”: more dimethyl sulfide in Arctic atmosphere
Released by phytoplankton, dimethyl sulfide may play an important role in regulating global climate.
Study shows warmest decade in the middle of Greenland in a thousand years
In the regions of Greenland where it is supposed to be coldest, researchers found a warming within ten years that was unprecedented in the last 1,000 years.
