Massive Antarctic Volcanic Eruptions Linked to
Abrupt Southern Hemisphere Climate Changes

New findings published today by Desert Research Institute (DRI) Professor Joseph R. McConnell, Ph.D.,document a 192-year series of volcanic eruptions in Antarctica that coincided with accelerated deglaciation about 17,700 years ago.“Detailed chemical measurements in Antarctic ice cores show that massive, halogen-rich eruptions from the West Antarctic Mt. Takahe volcano coincided exactly with the onset of the most rapid, widespread climate change in the Southern Hemisphere during the end of the last ice age and the start of increasing global greenhouse gas concentrations,” according to McConnell, who leads DRI’s ultra-trace chemical ice core analytical laboratory.read more

Antarctic sea ice level hit record low
But experts are not sure why

Unpredictable nature of Antarctic sea ice levels the focus at conference of metSea ice levels in Antarctica dropped to a record low this year, but experts say there is not a clear link to climate change.
More than 60 meteorologists and scientists from around the world are holding a week-long meeting in Hobart, Tasmania, to better understand sea ice changes on the frozen continent. Dr Jan Lieser from the Antarctic Climate and Ecosystems Cooperative Research Centre said sea ice levels had experienced a “massive increase” in variability over the past few years.

Scientists discover 91 volcanoes
under west Antarctica ice sheet

This is in addition to 47 already known about and eruption would melt more ice in region affected by climate change.The project, by Edinburgh University researchers, has revealed almost 100 volcanoes – with the highest as tall as the Eiger, which stands at almost 4,000 metres in Switzerland.Geologists say this huge region is likely to dwarf that of east Africa’s volcanic ridge, currently rated the densest concentration of volcanoes in the world.

Nearly 40.000 Adélie penguin chicks starved to
death in Antarctica this year

Only two Adélie penguin chicks out of a colony of 40,000 in Antarctica survived what researchers are calling a "catastrophic breeding event."
For the second time in four years, the Adélie penguins of Antarctica have suffered a devastating blow to their population. French researchers found the two surviving chicks on Petrels Island, Antarctica, and about 18,000 adult penguin pairs with their thousands of unhatched eggs and starved-to-death offspring.
