Bolivia’s Chacaltaya Glacier, once known as the world’s highest ski run at 17,388 feet, has completely melted away, serving as a vivid example of the effects of climate change on the glaciers around the globe.

Researchers in have discovered ancient, extremophile life forms that survive with neither light nor oxygen underground in Antarctica.

From the surface, the McMurdo Dry Valleys of Eastern Antarctica appears to be one of the most desolate places on Earth. And indeed it is. Apart from a few glaciers, the land is ice-free. No animals live here, and what few plants are able to are simple planktonic forms. But recently, a team of researchers have discovered evidence of a thriving community of extremophile microbes thriving several hundred feet below the barren surface.

Argentinian President Cristina Fernández vetoed a previously passed bill aimed at protecting Argentina’s glaciers.

Ever since I first saw Ernie and almost the entire felt-cast of Sesame Street do “The Rubber Duck, Duck” dance on Sesame Street, I have had a strange fascination with rubber ducks. They aren’t the common toy here in Australia that they appear to be elsewhere. And though looking back at that video now presents me with a bit of a moral and architectural dilemma, considering just how many people are naked together in that tub, my love for the rubber duck continues.

And now, once again, the rubber duck is coming to the aid of science. US rocket scientist Alberto Behar of NASA’s Jet Propulsion Laboratory in California has sent 90 rubber ducks into the Jakobshavn Glacier in Greenland in an attempt to figure out what is happening inside Greenland’s fastest moving glacier.

Fears about the Arctic melting away during northern summers are proving to be far from unfounded, with the latest reports rolling in from Alaska and Greenland showing disturbing trends. New shipping lanes are opening up through what were once icy seas near Alaska, and glaciers that have so far withstood much of what the environment has thrown at them in Greenland, are showing signs of breaking… literally.

Researchers who have been monitoring daily satellite images of Greenland’s glaciers from Ohio State University have discovered break-ups at two of the largest glaciers within the last month.

When we think about a problem as daunting as glacier melt, it’s tempting to throw up our hands and say that there’s nothing to be done. But researchers at Johannes Gutenberg University in Germany disagree. 27 students from the school recently set up a large structure in the Swiss Alps in an attempt to trap cold air over the Rhone glacier.

The giant windshield measures 49 feet by 10 feet (15 metres long and 10 meters high). The university says the shield has already been successfully tested in a laboratory.

The Swiss Alpine Museum in Bern is hosting a photographic exhibition which documents the gradual disappearance of many of Switzerland’s glaciers. Featuring contrasting photos of Swiss landscapes over the last 100 years the pictures reveal the full extent of glacial retreat in some regions.

Several hundred volunteers recently posed naked on a glacier in Switzerland, to raise awareness about climate change. New York artist Spencer Tunick, who has staged photo shoots of nude gatherings in cities around the world, teamed up with the environmental activist group Greenpeace to immortalize a "living sculpture" of the six hundred people atop the retreating Aletsch glacier.

The Great Aletsch is the largest and longest glacier in Europe, and forms part of

Glaciers are considered “global thermometers” and their shrinking numbers are watched closely by climate change scientists. Germany’s glaciers are suffering a faster fate than many, and locals dependent on the Zugspitze glacier for their livelihood are struggling to slow its demise.

In an area known for its winter skiing, and in a nation dependent on glaciers for drinking water, the melting of Germany’s last glacier is spurring some innovative – some say futile –
