Extreme melting on Greenland ice sheet observed – Glacial melt cycle could become self-amplifying

ScienceDaily (Oct. 25, 2011) – 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 […]

Photo gallery: Vanishing Glaciers of the Greater Himalaya

Stunning images from high in the Himalayas – showing the extent by which many glaciers have shrunk in the past 80 years or so – have gone on display at the Royal Geographical Society in central London. Between 2007 and 2010, David Breashears retraced the steps of early photographic pioneers such as Major E O […]

RealClimate: Greenland meltdown

By Gavin Schmidt21 September 2011 After a record-breaking 2010 in terms of surface melt area in Greenland [Tedesco et al., 2011], numbers from 2011 have been eagerly awaited. Marco Tedseco and his group have now just reported their results. This is unrelated to other Greenland meltdown this week that occurred at the launch of the […]

Groundwater greed driving sea level rises

By Michael Marshall25 September 2011 SLOWLY and almost imperceptibly the seas are rising, swollen by melting ice and the expansion of seawater as it warms. But there’s another source of water adding to the rise: humanity’s habit of pumping water from underground aquifers to the surface. Most of this water ends up in the sea. […]

Peter Ward: We’ve entered the Age of Mass Extinction – Goodbye fish and a whole lot more

By Scott Thill8 August 2011 Mass extinction is finally fighting its way back into the news cycle, thanks to recent scary reports on climate change from the International Programme on the State of the Ocean, the United Nations Environment Program and the July issue of Science. But University of Washington paleontologist Peter Ward has been […]

Antarctica rising as ice caps melt

July 31 (New Scientist) – ANTARCTICA is rising like a cheese soufflé: slowly but surely. Lost ice due to climate change and left-over momentum from the end of the last big ice age mean the buoyant continent is heaven-bound. Donald Argus of NASA’s Jet Propulsion Laboratory in Pasadena, California, and colleagues used 15 years of […]

Antarctica: A ‘quite scary’ source for rising seas

By John D. Cox28 July 2011 Before the last ice age, during a warm era some 125,000 years ago that was comparable to modern times, scientists know that the oceans reached levels that were some 15 to 20 feet higher than they are today. What they don’t know is, where did the extra water come […]

Researchers provide detailed picture of ice loss following collapse of Antarctic ice shelves

Contact: Patrick Lynch, NASA’s Goddard Space Flight Center, Greenbelt, Md., 757-897-2047, patrick.lynch@nasa.gov 25 July 2011 An international team of researchers has combined data from multiple sources to provide the clearest account yet of how much glacial ice surges into the sea following the collapse of Antarctic ice shelves. The work by researchers at the University […]

Colombia loses its glaciers – ‘Everything is changing so fast that I’m not sure what’s normal anymore’

By John Otis, Global Post22 July 2011 NEVADOS NATIONAL PARK, Colombia — Every year, the magnificent glacier-topped mountains of Nevados National Park attract thousands of tourists. But the snow and ice caps — called “nevados” in Spanish — are melting so fast that officials may have to come up with a new name for the […]
