Glaciers and ice caps to dominate sea level rise this century, says CU-Boulder study
Ice loss from glaciers and ice caps is expected to cause more global sea rise during this century than the massive Greenland and Antarctic ice sheets, according to a new University of Colorado at Boulder study. view more (2007-07-20)
New findings on immune system in amphibians
Krakow/Halle. Major Histocompatibility Complex (MHC) genes produce proteins that are crucial in fighting pathogen assault. Researchers from the Jagiellonian University in Krakow and from the Helmholtz Centre for Environmental Research (UFZ) characterized genetic variation and detected more than one MHC class II locus in a tailed amphibian. view more (2008-06-20)
Dust may settle unanswered questions on Antarctica
Dust trapped deep in Antarctic ice sheets is helping scientists unravel details of past climate change. view more (2009-03-30)
Antarctic research helps shed light on climate change on Mars
Researchers examining images of gullies on the flanks of craters on Mars say they formed as recently as a few hundred thousand years ago and in sites once occupied by glaciers. The features are eerily reminiscent of gullies formed in Antarctica's mars-like McMurdo Dry Valleys. view more (2008-08-29)
Climate change isolates Rocky Mountain butterflies
Expanding forests in the Canadian Rocky Mountains are slowly isolating groups of alpine butterflies from each other, which may lead to the extinction of the colourful insects in some areas, says a new study from the University of Alberta. view more (2007-08-14)
Alaska glacier speed-up tied to internal plumbing issues, says CU-Boulder study
A University of Colorado at Boulder study indicates meltwater periodically overwhelms the interior drainpipes of Alaska's Kennicott Glacier and causes it to lurch forward, similar to processes that may help explain the acceleration of glaciers observed recently on the Greenland ice sheet that are contributing to global sea rise. view more (2008-01-16)
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)
Desert dust alters ecology of Colorado alpine meadows
Accelerated snowmelt--precipitated by desert dust blowing into the mountains--changes how alpine plants respond to seasonal climate cues that regulate their life cycles. view more (2009-06-30)
Rewriting glacial history in Pacific North America
Although the story on glacier fluctuations in northwestern North America over the last 10,000 years has remained largely unchanged for decades, new evidence discovered by a University of Alberta researcher will rewrite that glacial history and offer clues about our climate history during the last several thousand years. view more (2006-01-10)
History book of lakes
Does man, through the felling of trees, alpine farming and atmospheric metal pollution produce a more negative effect on lakes than do natural changes, such as climate and vegetation? How long does it take until environmental protection measures actually show effect in lakes? Karin Koinig from the Institute of Zoology and Limnology at the... view more... (2001-02-22)
Glaciers not on simple, upward trend of melting
Two of Greenland's largest glaciers shrank dramatically and dumped twice as much ice into the sea during a period of less than a year between 2004 and 2005. And then, less than two years later, they returned to near their previous rates of discharge. view more (2007-02-13)
El Ni'ħo 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)
Iowa State scientist develops lab machine to study glacial sliding related to rising sea levels
Neal Iverson opened his laboratory's walk-in freezer and said the one-of-a-kind machine inside could help scientists understand how glaciers slide across their beds. And that could help researchers predict how glaciers will react to climate change and contribute to rising sea levels. view more (2009-11-11)
Glacial advances
The vast majority of the world's glaciers are retreating as the planet gets warmer. But a few, including glaciers south of the equator in South America and New Zealand, are inching forward. view more (2009-05-04)
Glacial pace of erosion was not so slow, new technique shows
Glaciers, rivers and shifting tectonic plates have shaped mountains over millions of years, but earth scientists have struggled to understand the relative roles of these forces and the rates at which they work. view more (2005-12-12)
Small glaciers in the tropical Andes : a forewarning of disappearance
In ten to fifteen years' time, the small glaciers of the Andes, which constitute 80% of all the glaciers in the tropical regions of that mountain chain, are likely to have vanished. That is the main conclusion reached after studies conducted on the Chacaltaya glacier in Bolivia and on that of Antizana in Ecuador. Performed by French scientists... view more... (2001-01-16)
NASA Scientist Claims Warmer Ocean Waters Reducing Ice Worldwide
According to a NASA scientist, the pieces to a years-old scientific puzzle have come together to confirm warmer water temperatures are creeping into the Earth's colder areas. Those warm waters are increasing melting and accelerating ice flow in polar areas. view more (2006-03-24)
Greenland glaciers dumping ice into Atlantic at faster pace
The amount of ice that Greenland's glaciers dump into the Atlantic Ocean has almost doubled in the last five years because glaciers are moving faster, according to a new Science study. view more (2006-02-17)
A health check for the Earth @ the London `Catastrophes` conference
The condition of our environment at any time reflects not only human influences but also natural processes and phenomena, which may be causing change - whether or not people are present. So how do we know when humans are to blame and when it`s just the environment behaving `naturally`. At Brunel University`s `Environmental Catastrophes`... view more... (2002-08-17)
Malham Cove yields icy secrets to diving scientist
One of the most well-known features of the Yorkshire landscape is nearly four times older than previously thought, cave diver and earth sciences technician Phillip Murphy has established. view more (2002-04-25)
