[ Watch the Video ] In a new study led by researchers at the University of Colorado at Boulder, scientists using NASA data have found that Earth´s glaciers and ice caps outside of the regions of Greenland and Antarctica are losing nearly 150 billion tons of ice annually. Using satellite measurements from the NASA/German Aerospace Center Gravity Recovery and Climate Experiment (GRACE), researchers were able to measure ice loss in all of Earth´s land ice between 2003 and 2010....

Extreme Melting On Greenland Ice Sheet Reported

Glacial Melt Cycle Could Become Self-Amplifying, Making it Difficult to Halt The Greenland ice sheet can experience extreme melting even when temperatures don´t hit record highs, according to a new analysis by Dr. Marco Tedesco, assistant professor in the Department of Earth and Atmospheric Sciences at The City College of New York.  His findings suggest that glaciers could undergo a self-amplifying cycle of melting and warming that would be difficult to halt. “We are...

An international team of scientists, led by Dr Stephen Barker of Cardiff University, has produced a prediction of what climate records from Greenland might look like over the last 800,000 years. Drill cores taken from Greenland's vast ice sheets provided the first clue that Earth's climate is capable of very rapid transitions and have led to vigorous scientific investigation into the possible causes of abrupt climate change. Such evidence comes from the accumulation of layers of ancient...

An analysis of prehistoric "Heinrich events" that happened many thousands of years ago, creating mass discharges of icebergs into the North Atlantic Ocean, make it clear that very small amounts of subsurface warming of water can trigger a rapid collapse of ice shelves. The findings, to be published this week in Proceedings of the National Academy of Sciences, provide historical evidence that warming of water by 3-4 degrees was enough to trigger these huge, episodic discharges of ice from the...

Bt Jill Sakai, University of Wisconsin-Madison During the last prolonged warm spell on Earth, the oceans were at least four meters "“ and possibly as much as 6.5 meters, or about 20 feet "“ higher than they are now. Where did all that extra water come from? Mainly from melting ice sheets on Greenland and Antarctica, and many scientists, including University of Wisconsin-Madison geoscience assistant professor Anders Carlson, have expected that Greenland was the main culprit. But...

Melting ice sheets contributed much more to rising sea levels than thermal expansion of warming ocean waters during the Last Interglacial Period, a UA-led team of researchers has found By Daniel Stolte, University of Arizona Thermal expansion of seawater contributed only slightly to rising sea levels compared to melting ice sheets during the Last Interglacial Period, a University of Arizona-led team of researchers has found. The study combined paleoclimate records with computer simulations of...

2010 one of the two warmest years on record Worldwide, 2010 was one of the two warmest years on record according to the 2010 State of the Climate report, which NOAA released today. The peer-reviewed report, issued in coordination with the American Meteorological Society, was compiled by 368 scientists from 45 countries. It provides a detailed, yearly update on global climate indicators, notable climate events and other climate information from every continent. This year's report tracks 41...

A team of scientists from the University of Sheffield and Bangor University have used a computer climate model to study how freshwater entering the oceans at the end of the penultimate Ice Age 140,000 years ago affected the parts of the ocean currents that control climate. A paper based on the research, co-authored by Professor Grant Bigg, Head of the University of Sheffield's Department of Geography, his PhD student Clare Green, and Dr Mattias Green, a Senior Research fellow at Bangor...

ESA's CryoSat team working on the Greenland ice sheet has been honored with a visit from a Dutch delegation including HRH Prince of Orange. The visit is part of a tour to learn more about climate change in polar regions and consequences for the environment. Prince Willem-Alexander's visit to Greenland was at the invitation of the World Wide Fund for Nature-Netherlands. The delegation included Johan van de Gronden, CEO of WWF-NL, Robbert Dijkgraaf, President of the Royal Dutch Academy of...

According to an international report, climate change in the Arctic could raise world sea levels to 5 feet by 2100. A rise like this would threaten the coasts from Bangladesh to Florida, low-lying Pacific islands and cities from London to Shanghai.  It would also raise costs of building tsunami barriers in Japan. "The past six years (until 2010) have been the warmest period ever recorded in the Arctic," according to the Oslo-based Arctic Monitoring and Assessment Programme (AMAP). "In...
