A survey of the region of the West Antarctic Rift System has revealed 91 new volcanoes hidden within the ice. The new volcanoes are on top of the 47 whose peaks are above the ice and were already known about. The volcanoes range in height from 100m to a towering 3,850m tall. Geologists say the range has similarities to east Africa’s volcanic ridge, which was previously thought to have the densest concentration of volcanoes in the world.
The ice sheets of central Antarctica have been stable for millions of years when conditions were warmer than now, a new research has found. Researchers from the Universities of Edinburgh and Northumbria studied rocks on slopes of the Ellsworth Mountains in Antarctica, whose peaks protrude through the ice sheet. However, the scientists are concerned that ice at the coastline is vulnerable to rising temperature, though the discovery points towards the long-term stability of Antarctica’s ice sheet.
The new research calls into question recent claims of much more dramatic ice loss.
Study finds Antarctic peninsula "regionally stacked temperature record for the last three decades has shifted from a warming trend of 0.32 °C/decade during 1979–1997 to a cooling trend of − 0.47 °C/decade during 1999–2014."
