New map reveals how little of Antarctica’s rock is ice-free
Read more of: New map reveals how little of Antarctica’s rock is ice-freeUntil now estimates of how much of ice-free rock is exposed in Antarctica were stated as ‘less than 1%’. For the first time scientists from British Antarctic Survey (BAS) have […]

Polar ice reveals secrets of carbon-climate feedbacks
Read more of: Polar ice reveals secrets of carbon-climate feedbacksAn international team of scientists have used air bubbles in polar ice from pre-industrial times to measure the sensitivity of the Earth’s land biosphere to changes in temperature.

Albatrosses use different regions when on migration
Read more of: Albatrosses use different regions when on migrationA new study of the movements of sub-Antarctic albatrosses tracked from two remote islands some 5,000 km apart, shows that although the birds from each breeding site take similar routes around the Southern Ocean, they forage in different areas for the majority of the time. The results are published this month in the Nature journal Scientific Reports.

A recent pause in Antarctic Peninsula warming
Read more of: A recent pause in Antarctic Peninsula warmingThe rapid warming of the Antarctic Peninsula, which occurred from the early-1950s to the late 1990s, has paused. Stabilisation of the ozone hole along with natural climate variability were significant in bringing about the change. Together these influences have now caused the northern part of the peninsula to enter a temporary cooling phase. Temperatures remain higher than measured during the middle of the 20th Century and glacial retreat is still taking place. However, scientists predict that if greenhouse gas concentrations continue to rise at the current rate, temperatures will increase across the Antarctic Peninsula by several degrees Centigrade by the end of this century.

Ocean warming primary cause of glacier retreat
Read more of: Ocean warming primary cause of glacier retreatA new study has found for the first time that ocean warming is the primary cause of retreat of glaciers on the Antarctic Peninsula. The Peninsula is one of the largest current contributors to sea-level rise and this new finding will enable researchers to make better predictions of ice loss from this region.

Wind-blown Antarctic sea ice helps drive ocean circulation
Read more of: Wind-blown Antarctic sea ice helps drive ocean circulationAntarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study published today in the journal Nature Geoscience (Monday 27 June) shows how that ice migration may be more important for the global ocean circulation than anyone realized.
