Alps Glaciers to disappear by 2050!
This loss of glaciers could lead to loss and change in supply of drinking and irrigation water, leading to more falling rocks, and destroy the European ski industry.
On an average around 3 percent of Alpine glacial ice is lost every year, according to Roland Psenner, a fresh water scientist at the University of Innsbruck in Austria. That corresponds to around 3.3 feet (1 meter) of ice thickness.
Ten percent of the ice was gone in the record-breaking heat of 2003. Around seven percent was gone in 2006 according to Psenner.
“If the melting goes on at this pace, glaciers will be gone by 2030 to 2050—except some high-altitude sites in the French, Swiss, and Italian Alps,” he wrote in an email to National Geographic News.
Yet another Warning!
Lonnie Thompson is a glaciologist at the Byrd Polar Research Center at Ohio State University. He says that the loss of glacier ice in the Alps is consistent with global trends. It is the same story all over the world.
“At all these sites it’s the same story. Not only are the glaciers retreating, they are accelerating in the rate at which they are retreating,” Thompson said. “That’s very consistent with what’s going on with the glaciers in the Alps.”
That Alpine glaciers are melting fast is old news to European ski resorts, which are watching the multimillion-dollar winter tourism trade trickle away.
Cause for Melting
Global warming along with the greenhouse gases seems to be the main cause of the melting glaciers. Studies also suggest that Alpine glaciers almost disappeared at least once in the past 10,000 years.
This melting trend is consistent with the projections that were made based on warming occurring due to increase in greenhouse gases in our atmosphere.
It is important to note that the past glacial melting occurred when atmospheric levels of the greenhouse gas carbon dioxide (CO2) were 280 parts per million. Today’s carbon dioxide levels are approaching 385 parts per million.

A very rare river terrapin was found for the first time since 20 years in the Thai province of Phang Nga. This river terrapin was considered to be extinct in Thailand, before the villagers caught this female turtle on January 3, 2007, in a mangrove canal on the country’s Andaman coast.
Gas drilling on the Indonesian island of Java has triggered what can be called a “mud volcano” that had killed around 13 people and has made four square miles (ten square kilometers) of countryside uninhabitable for years.
It’s summer down under, and at many Australian beaches the sands have turned as blue as the water. Many big armadas of toxic bluebottle jellyfish have swamped the Australia’s east coast in such huge numbers on the peak beach season.
