Global Warming Causing Alarming Glacier Meltdown

August 8, 2009

(ChattahBox)—Our glaciers, long considered a benchmark for the effects of global warming, are melting and receding at an alarming rate, with scientists predicting as a result, increasing worldwide sea levels and flooding of low-lying coastal communities, rendering the areas inhabitable.

The scientists with the U.S. Geological Survey have monitored three glaciers located in Alaska and Washington State, for 50 years and issued a new report on their findings, showing an accelerated wasting away of the glaciers during the past 15 years, which is caused by the global warming of our planet.

Lead researcher Edward Josberger, with the USGS Washington Water Science Center in Tacoma, Washington, likened the accelerated glacier melting as the “canary in the coal mine,” warning the world of the deadly changes to come. The scientists began monitoring the three glaciers in 1959 and they have never recorded during that time, such a decrease in the mass balance of the glaciers.

The meltdown and retreat of the glaciers also coincides with the highest melt years on record, as the melting water from the glaciers floods delicate ecosystems and rivers.

The scientists have been collecting annual data from three glaciers that represent three climatic regions in the United States; the South Cascade Glacier in the Cascade Mountains of Washington State, the Wolverine Glacier on the Kenai Peninsula near Anchorage, Alaska and the Gulkana Glacier in the interior of Alaska.

The long-running geological survey measures climate, glacier geometry, glacier mass balance, glacier motion and stream runoff, to determine with scientific accuracy, the effects of climate change. The scientists have half a century of data, showing the amount of snow covering the glaciers each year, compared to the amount of melting every summer. This comparison shows a significant loss of mass in all three monitored glaciers.

For example, Washington’s South Cascade glacier has lost half its volume since 1960 and is predicted to lose an additional half in the next 100 years. Photographic evidence over the fifty-year study period illustrates the disturbing effects of global warming, more powerfully than the scientific data alone, as the glaciers melt away and retreat further up into the mountain valleys each year.

“We feel it’s definitely the signature of global change and climate warming,” said Josberger. The entire study can be found here.

    Global warming is a government facade. WHomever runs this site and writes the news hasn’t done their history reading on climates going back to medieval times and the direct correlation with solar activity. In other words this is a bogus sham and it will begin to cool when this solar activity subsides.

    Do you believe breathing mammals expunging CO2 is bad? This site is a joke.

    As noted above about the medieval warm period, there have been mines found in Alps after some glaciers retreated. If the trend today has everything to do with CO2 and not natural variation then why was there no ice in this area before?

    The only “scientific” proof that has been put forth for man made global warming has been “its getting warmer” (which it stopped getting warmer about 12 years ago) and “there is more CO2 in the air”. All the other papers and research is snake oil.

    if u wait till its to late… its too late.

    obviously depending upon fossil fuels is … foolish.

    Can’t believe some people still don’t take global warming seriously. The planet has been getting hotter and that’s a fact. Denying of the fact is utter ignorance and a shame.

    A@ BS – So burning all the oil and coal in the world over the next 100 years (as planned) won’t raise the temp of the earth one bit? Water freezes at 32 degrees F and melts at 33. All its takes is a little change to make a HUGE impact.

    Last time I had a fever I felt miserable. My temp was 101. Normal is 98.6, death occurs at 104… so only 2.4 degrees can send a human into misery. Do you think anything may happen if earth temps do rise?

    People build green houses for a reason, to keep plants warm during cold times. There is no need for humans to build an artificial green house.

    Dinosaurs died for a reason… lets not repeat it by digging up and burning them.

    In the Little Ice Age glaciers destroyed mountain villages in the Alps and priests were enlisted to try and stop their progress by divine intervention. The 17th century was particularly devastating with much loss of life, decline of agriculture and widespread starvation. This is a matter of historical record and easily found.

    By 1860 the Little Ice Age was ending and glaciers retreated on a massive scale . By 1900 many glaciers had receded more than two kilometers in just forty years. I wonder what the headline writers would have said back then, or what the blogosphere would have been like.

    A good reference on the little Ice Age is Fagan 1999 chapter on LIA “Floods, Famines, and Emperors: El Niño and the Fate of Civilizations” (Basic Books, 1999).

    Bush cost us 8 years of progress on climate change. And there are still those in denial out there, incredible. There is a related post at http://iamsoannoyed.com/?page_id=588

    People living in states that depend on glacial meltwater for drinking and irrigation better wise up…fast. Instead of spending money on green this or that, or on expensive energy alternatives to cheap oil and coal, they should spend their money in the search for alternative sources of water.

    We need alternative sources of water more than alternative sources of energy.

    Adaptation will serve us all much better than any attempts to switch to alternative sources of energy… whether or not manmade CO2 emissions are causing the glaciers to melt.

    And the Indians say the exact opposite.

    Why must scientists always use “proxies”? Why can’t they measure ALL the glaciers? They might come up with different results. Instead they look at the three that are melting and say it’s happening to all of them. That’s not science. It’s junk science.
