West Antarctic Melt Rate has Tripled

By Antarctica, Glaciers, ice sheet, ice sheets, Sea Level Rise, West Antarctic Ice Sheet

Researchers at UC Cal Irvine and NASA, using four different measurement techniques, have found that West Antarctica’s ice loss has tripled since 1992. The measurements looked at glaciers discharging to a west central location of West Antarctica called the Amundsen Sea Embayment (see Amundsen Sea in the map on the right). This could possibly be…

CO2 emissions from the Southern Ocean (and) Climate Models are Different from Weather Models

By Antarctica

We have another mechanism conspiring to launch our planet into abrupt climate change. The Great Southern Ocean, or the Antarctic ocean is the culprit this time. Work out of the University of Zurich, Switzerland, Columbia University, Cambridge and Princeton has taken a million year look at sediment two sediment cores from the Antarctic. They found…

Warming Ocean Waters Around Antarctica Allow King Crabs Migrate to the Antarctic Ocean for the First Time In 40 Million Years

By Antarctica

Sounds good?  More king crab is always good! Except when you are the vast southern oceans biologic community that has not seen claws or pinchers for forty million years. This development has been caused by a warming southern ocean, that is of course attached to the rest of the world’s oceans that are warming because…

Antarctica is Still Warming

By Antarctica

February 1, 2011 – A paper by Stieg et. al. in 2009, widely accepted as the best  in Antarctic temperature analysis in recent history, has recently come under fire from a paper by O’Donnell, et. al. O’Donnell’s paper says that warming in Antarctica is only half of what Stieg says.  The denialists are wild with…

Antarctica melt / ice loss accelerates

By Antarctica

Recent studies using the new GRACE gravity measuring satellites (see here) have shown startling new results for ice melt / ice loss from Antarctica.  As the dataset from the new satellites, put up in 2003, grows larger, the melt / ice loss continues to grow. Previous studies have shown the melt/loss coming mainly from West…

Catastrophic Change and Climate Blindness

How do we curb emissions with the way our society has evolved? Really. I mean serious curbing; enough to prevent dangerous climate change? When considering the answer, dangerous climate change must be clearly defined. So, what exactly is dangerous climate change?

Antarctic Ice Report from the USGS – authors say "widely regarded as among the most profound and unambiguous examples of the effects of global warming yet seen on the planet"

By Antarctica

Antarctica is shrinking and the rate of melt and ice discharge is accelerating. In the last 20 years an area of ice almost the size of Alaska has been lost. Every ice front on the southern section of the peninsula has been retreating from 1947 to 2009, with the most dramatic changes since 1990.This U.S….

Wilkins Ice Sheet Collapses – The Size of Connecticut: Implications for the West Antarctic Ice Sheet

By Antarctica

The disintegration of the largest ice shelf ever known to collapse started in February 2008 during the Antarctic summer. Signs of the breakup continued during the deep polar winter, something else that has never been seen before. The European Space Agency has now announced that the breakup amounts to 14,000 square kilometers, or over 5,000…
