Over the past 40 years, ice cores have revealed more about climate change than any other scientific technique. Over the last few decades, satellites have detected changes to the amount of sea ice that covers the polar oceans. Since 1979 summer sea-ice extent in the Arctic has reduced at 10% per decade. Some major glaciers that drain the Antarctic and Greenland ice sheets have accelerated by as much as 50%.

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
