Investigating physical and chemical changes in atmospheric circulation, ozone depletion, temperatures and sea-ice extent in both Polar Regions can help determine how much of the observed change is due to human activity and how much is a result of natural factors. Unique chemical processes occur in the atmosphere above Antarctica and the Arctic reveal much about our changing world.

A recent pause in Antarctic Peninsula warming

20 July, 2016

The 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

14 July, 2016

A 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.
