The 15 most toxic places to live

9 not-so-crazy ways to combat global warming

7. The Matterhorn

Many often wonder why Europeans get so hot and bothered about climate change. Perhaps it has something to do with the fact that they are in direct, daily contact with one very sobering reality — their ice is vanishing. 

European glaciers have been some of the hardest hit by climate change. Since the first half of the 19th century, about two-thirds of the ice cover was lost in the Pyrenees with a marked acceleration after 1980 (Chueca et al. 2005 via: UNEP) and in the Alps, home to the world famous Matterhorn, nearly half the glaciers have disappeared since record keeping began.

Often called the "water tower" of Europe, the Alps contain 40 percent of Europe's fresh water supply. The dramatic disappearance of ice on the Matterhorn last year has prompted the need for the border between Switzerland and Italy to be redrawn.
 

6. Alaska

It's always struck me as a bit ironic that Alaska, home to several of the most famous gubernatorial climate skeptics (including Sarah Palin) is also home to some of the most dramatic examples of climate change. The astonishing recession of the massive Muir glacier is just one example among dozens (see graphs below), causing many scientists to warn of earthquakes triggered by tectonic plates with suddenly lightened loads. 

5. Himalayas

Home to the planet's largest body of ice outside the polar caps, the Himalayas feed several of the world’s largest rivers, supporting close to a billion people. In the western region of Himachal Pradesh, new evidence tracks an annual ice loss of nearly 3 feet in thickness per year, doubling in the past decade from the decade prior (Berthier et al, 2007).

Will the Himalayan glaciers disappear this century? Not likely, but Chinese government officials are growing concerned that retreating ice may spell the end of reliable water supplies for China.

4. Greenland

Satellite images of Greenland’s Helheim Glacier dating back to the 50s shows that this massive glacier has remained in tact for decades. But In 2000 it suddenly began disappearing. By 2005 the glacier had retreated a total of 4 1/2 miles — at an average rate of 110 feet per day. Ironically, retreating glaciers in Greenland have enabled dozens of new oil and gas exploration projects as vanishing ice makes room for heavy drilling equipment.

3. Mount Kilimanjaro

Last week a band of celebrities hiked up Mount Kilimanjaro to raise awareness for the African water crisis. The famous snow-cap formed 11,000 years ago but has diminished more than 85 percent since 1912, and nearby Mount Kenya has lost nearly ALL of its ice at an average of 1 meter per year, threatening water supplies for millions of people. Scientists now predict that the last great African glaciers could be gone within 20 years.
 

2. The Andes

The Chacaltaya glacier, once the highest ski resorts on earth, has completely vanished in the relative blink of an eye. A study on Bolivian glaciers in 1998 predicted the glacier’s disappearance by the year 2015, a claim that at the time was dismissed as overly dramatic. But early last year, it was officially announced that the glacier ”... no longer exists,” an event which threatens both water and power supplies in the Andean region.

Melting has tripled in the last decade, and it is expected that several adjoining clusters could have less than 30 years to survive.

1. Glacier National Monument

Glacial National Park — 1938 & 2005

Based on the latest reports, Montana may have to think of a new name for its famous Glacier National Monument. Of the 38 square-mile area once covered by glaciers, less than 25 percent remains. Researchers believe that by the year 2030, the vast majority of ice in Glacier National Park will be gone unless current climate patterns are reversed.

ADDENDUM: The GRID Report (PDF) has just released new data for its upcoming 2007/2008 report which shows ever-increasing rates of deglaciation. It's filled with dozens of almost incomprehensible graphs like this one which shows that of the 16 major glaciers studied, all 16 are rapidly melting:
