New Tibetan ice cores missing A-bomb blast
Ice cores drilled last year from the summit of a Himalayan ice field lack the distinctive radioactive signals that mark virtually every other ice core retrieved worldwide. That missing radioactivity, originating as fallout from atmospheric nuclear tests during the 1950s and 1960s, routinely provides researchers with a benchmark against which they... view more...

El Ni'得 and glacier melt in the tropical Andes
Glacier regression in the tropical Andes has accelerated considerably over the past 30 years. This change is cause for great concern, insofar as many regions of the Andes depend on the Cordillera's glaciers for their water supply (2). In 1991 scientists from the IRD research unit Great Ice (UR032) set up an observation network, jointly with their... view more... (2004-10-21)

Climate change means time is running out for ski resorts built on glaciers
As the first snowfalls mark the opening of the new skiing season in Europe, glaciologists at the University of Wales, Aberystwyth (UWA) are warning that time may be running out for ski resorts built on glaciers. Dr Bryn Hubbard of the Centre for Glaciology at UWA is studying the response of some of the world's most sensitive ice masses to climate... view more... (2003-11-26)

Patagonian glacier yields clues for improved understanding of global climate change
A better understanding of climate variations at planetary scale is one of climate scientists' crucial concerns. Stable water isotope analysis, the chemistry of ice cores taken from the Arctic and Antarctic polar ice caps and of air bubbles trapped in them now allow a chronology to be drawn up of the climate changes that took place over the past... view more...

Mars' climate in flux: Mid-latitude glaciers
New high-resolution images of mid-latitude Mars are revealing glacier-formed landscapes far from the Martian poles, says a leading Mars researcher.   view more (2005-10-18)

The woes of Kilimanjaro: Don't blame global warming
The "snows" of Africa's Mount Kilimanjaro inspired the title of an iconic American short story, but now its dwindling icecap is being cited as proof for human-induced global warming.   view more (2007-06-12)

Rapidly accelerating glaciers may increase how fast the sea level rises
Satellite images show that, after decades of stability, a major glacier draining the Greenland ice sheet has dramatically increased its speed and retreated nearly five miles in recent years.   view more (2005-11-15)

New study shows much of the world emerged from last Ice Age together
The end of the recurring, 100,000-year glacial cycles is one of the most prominent and readily identifiable features in records of the Earth's recent climate history. Yet one of the most puzzling questions in climate science has been why different parts of the world, most notably Greenland, appear to have warmed at different times and at different... view more...

Greenland melt accelerating, according to CU-Boulder study
The 2007 melt extent on the Greenland ice sheet broke the 2005 summer melt record by 10 percent, making it the largest ever recorded there since satellite measurements began in 1979, according to a University of Colorado at Boulder climate scientist.   view more (2007-12-12)

Breakup of glaciers raising sea level concern
The rapid structural breakdown of some important parts of the ice sheets on Greenland and Antarctica is possible, has happened in the distant past, and some "startling changes" on the margin of these ice masses has been observed in recent years - raising disturbing concerns about sea level rise.   view more (2005-10-21)

Radar altimetry confirms global warming is affecting polar glaciers
Scientists have confirmed that climate warming is changing how much water remains locked in the Antarctic and Greenland ice sheets, according to an article published in the Journal of Glaciology.   view more (2006-03-20)

NASA researchers find snowmelt in Antarctica creeping inland
On the world's coldest continent of Antarctica, the landscape is so vast and varied that only satellites can fully capture the extent of changes in the snow melting across its valleys, mountains, glaciers and ice shelves.   view more (2007-09-21)

Antarctic ice loss speeds up, nearly matches Greenland loss
Ice loss in Antarctica increased by 75 percent in the last 10 years due to a speed-up in the flow of its glaciers and is now nearly as great as that observed in Greenland, according to a new, comprehensive study by UC Irvine and NASA scientists.   view more (2008-01-24)

El Ni'得 et la fonte des glaciers dans les Andes tropicales
Dans les Andes tropicales, le recul des glaciers s'est considérablement accéléré depuis une trentaine d'années. Cette évolution est d'autant plus inquiétante que l'approvisionnement en eau de nombreuses régions andines dépend des glaciers de la Cordille're (2). Afin de mieux... view more... (2004-09-27)

Research team draws 150-meter ice core from McCall Glacier
A 150-meter ice core pulled from the McCall Glacier in the Arctic National Wildlife Refuge this summer may offer researchers their first quantitative look at up to two centuries of climate change in the region.    view more (2008-07-11)

Permanent ice fields are resisting global warming
The small ice caps of Mont Blanc and the Dôme du Goûter are not melting, or at least, not yet. This is what CNRS researchers1 have announced in the Journal of Geophysical Research.   view more (2007-05-17)

NASA flies to Antarctica for largest airborne polar ice survey
NASA begins a series of flights Oct. 15 to study changes to Antarctica's sea ice, glaciers and ice sheets. The flights are part of Operation Ice Bridge, a six-year campaign that is the largest airborne survey ever made of ice at Earth's polar regions.   view more (2009-10-09)

DNA provides 'smoking gun' in the case of the missing songbirds
It sounds like a tale straight from "CSI": The bully invades a home and does away with the victim, then is ultimately found out with the help of DNA evidence.   view more (2008-11-05)

Climate History Rewritten: Arctic Ice an Early Arrival
For the first time, scientists have pulled up prehistoric geologic records from the frigid vault of the Arctic Ocean. One of the findings, evidence of glacial Arctic ice from 45 million years ago, recasts a critical chapter of global climate history.   view more (2006-06-01)

Climate change could impact vital functions of microbes
Global climate change will not only impact plants and animals but will also affect bacteria, fungi and other microbial populations that perform a myriad of functions important to life on earth.   view more (2008-06-03)
