    Some Himalayan Glaciers Growing Despite Warming
    Michael Reilly, Discovery News

    Shrinking? Not So Much--Discovery News Video May 5, 2009 -- Perched on the soaring Karakoram mountains in the Western Himalayas, a group of some 230 glaciers are bucking the global warming trend. They're growing.

    Throughout much of the Tibetan Plateau, high-altitude glaciers are dwindling in the face of rising temperatures. The situation is potentially dire for the hundreds of millions of people living in China, India and throughout southeast Asia who depend on the glaciers for their water supply.

    "These are the biggest mid-latitude glaciers in the world," John Shroder of the University of Nebraska-Omaha said. "And all of them are either holding still, or advancing."

    When Shroder and a team of researchers examined satellite imagery of the region's glaciers dating back to 1960, they found that 87 glaciers had surged forward during that time, sliding down into lower elevations. An analysis of gravity signatures in the region also suggests the glaciers are growing in mass, and have been since at least 1980.

    The team's work will be published in a forthcoming issue of Annals of Glaciology.

    Surging glaciers are common and do not necessarily mean a glacier is growing in overall size. But the fact that dozens of them have all surged in the same region hints that larger climate forces are at work.

    "It looks like it's the Westerlies," Shroder said, referring to strong jets of wind that pour from west to east in a belt around the planet. Though he can't say for certain, the winds appear to be carrying more moisture from the warming Atlantic Ocean and Mediterranean Sea eastward.

    If that's true, some of the moisture would fall into the region around the Caspian Sea. But as the winds rise into Karakoram's frigid heights, any remaining water would come down as snow, feeding the glaciers.

    "We will see regional patterns like this developing as climate change alters precipitation," said Andrew Fountain of Portland State University in Oregon.

    Yup. The global warmers will cherry pick some glaciers as retreating due to warming. Then they will just as easily explain that the many glaciers that are in fact growing are doing so because of..........global warming.

    They even manage to say it with a straight face. Remarkable!

    Sinatra, are you unable to understand what you read? Where the normal wind patterns have been altered by the warming, and carry more precipitation to the mountains, there are some glaciers that are growing. Just as in Continental USA, the glaciers on Shasta are presently growing because Shasta is getting more precip, the glaciers in that part of the Himalyas are growing. But most of the glaciers in the Himalyas are rapidly shrinking, as that very article states.

    Now who did the cherry picking? Sheesh, what an idiot!

    Yeah well I can see how this might happen even in a situation of Global warming.

    All it would take is a change in weather patterns such that more moisture was directed toward those mountains.

    The term global warming might be technically correct, but it confuses people, too.

    They really ought to call it GLOBAL WEIRDING.

    :lol:

    Yes, it still gets back to the now oft-used arguement that global warming causes...cooling. In some areas mind you!

    But it's still warming...only not in all areas. Just some areas. But it's Global Warming.

    Really.

    It is.....

    Region
    Observations

    Circum-Arctic
    Glaciers have generally lost mass over the last 30 years. In East and West Greenland glaciers are retreating rapidly while in North Greenland the situation is unclear. Svalbard glaciers are losing mass


    Central Asia

    From the 1950s to the 1980s, 73% of glaciers were retreating, 15% were advancing and 12% were stable.

    Tropical mountains
    The retreat of glaciers has been documented in the Ecuadorian Andes, New Guinea, East Africa (Mount Kenya's glacier has receded markedly since the late 1800s and since the 1960s its mass has decreased by 40%), Venezuela and Peru.

    New Zealand
    Most glaciers have retreated during the 20th century. The Tasman Glacier has thinned by more than 100m. Since 1983, the recession of western glaciers has reversed and these glaciers are growing (e.g. the Franz Josef glacier).

    Southern and central South America
    The Upsala glacier has retreating about 60m per year over the last 60 years and this rate appears to be accelerating. In the last 40 years, the area of the South Patagonian Ice Field has diminished by about 500km2. The Soler and Tyndall Glaciers also appear to have lost mass, while the Pio XI glacier in Patagonia is larger now than at any time in the last 6,000 years.

    Europe
    For the Alps as a whole, the glacial area since about 1850 has been reduced by 30-40 percent, with about a 50 percent reduction in ice volume. However, this has been counterbalanced by the recent growth of some larger glaciers in the Alps such as the Grosse Aletsch in Switzerland and many Scandinavian glaciers, resulting in a small net increase in glacial ice over the last 30 years.

    Antarctica and sub-Antarctic Islands
    The alpine glaciers of the Dry Valleys in Antarctic have fluctuated with no apparent trends. Numerous glaciers along the Antarctic Peninsula are in retreat. Glaciers in many sub-Antarctic islands are also in retreat, for example, some small glaciers in Heard Island have decreased by up to 65%.

    You fellows are the ones trying to spin reality. You know full well that there is an overwhelming scientific consensus on the fact that we are changing the climate in a way that will have major negative impacts on humanity. But you cannot admit it as it runs contrary to your ideology.

    We have seen for eight years what the results are of policy controlled by ideology are. We have seen that ideology with no connection to reality, when driving policy, in whatever realm, results in catastrophe. But here you are, still insisting that we continue such idiocy. A certain consistancy in insanity there, old boy.
