    Effect of Collapsed Ice Sheet Revised

    By RANDOLPH E. SCHMID, AP
    posted: 12 HOURS 5 MINUTES AGOcomments: 316filed under: Science NewsPrintShareText SizeAAAWASHINGTON (May 14) -

    The global sea level will only rise about 10 feet if the West Antarctic ice sheet collapses.
    While that may not sound so great to residents of coastal cities like New York or Los Angeles, it's only about half the previously predicted rise.

    If the West Antarctic ice sheet collapses, the global sea level will rise about 10 feet, researchers said in the May 15 edition of the journal Science. That's about half the rise that was previously predicted. Scientists say most of the increase would occur along the East and West Coasts of the U.S. Here, ice melts near Biscoe Island in Antarctica.

    Researchers led by Jonathan L. Bamber of the University of Bristol in Britain report their recalculation of the hazard in Friday's edition of the journal Science. However, they add, the maximum increase is expected along the East and West Coasts of the United States, where the water could rise as much as 25 percent more than in other regions.
    The West Antarctic Ice Sheet can be unstable and has long concerned researchers who fear it could collapse as a result of global warming.
    Previous studies had estimated that failure of the ice sheet, causing it to slide into the ocean, would raise global seas levels by 5-to-6 meters, or 16-to-19 feet.

    Sea Level Rise

    And this is the reason so many of us question the effects of global warming or if it is even caused by human activity. What will the next revision state? Maybe they will again revise this to a sea level rise of only three feet. Maybe they will say "oops, we were just a little off on our models".

    Wouldn't the sea level rise everywhere equally, while a similar rise everywhere would encroach horizontally more on land areas closer to sea level?

    The ocean bordering North American coastal cities like New York, Washington, D.C. and Los Angeles may rise by more than 20 feet if the West Antarctic ice sheet melts due to global warming, new research suggests. That figure is 25 percent higher than previous estimates and 30 percent higher than the average predicted rise worldwide.

    Although there is no consensus among experts on whether such catastrophic Antarctic melting is likely, the new study suggests that if it does occur, quirks of global geology would cause the waters on both coasts of North America to rise higher than in most other parts of the world. The increase would be six to seven meters, or as much as 23 feet. That’s enough to drastically affect life along the U.S. coastline, according to the study, which was published February 6 in the journal Science.

    Earlier estimates of the potential impact of West Antarctic melting, including in the 2007 Fourth Assessment Report of the United Nations’ Intergovernmental Panel on Climate Change, or IPCC, predicted sea level would rise uniformly throughout the world, like water in a bathtub, by about five meters, or 16 feet. The new study, however, identifies three factors that demonstrate that the increase would be highest in North American coastal waters.

    “For those of us who live in North America, the effects examined in the study combine in a triple whammy,” says Jerry X. Mitrovica, a geophysicist at the University of Toronto in Canada, and lead author of the predictive study. “[North Americans] will experience the largest amplification in sea level.”

    Thje Holy Grail of all of the is stuff is that there is a consensus. There is no consensus on this particular part of it. Also, those who do endorse this stipulate that it will take hundreds of years for the ice shelf to melt if it does.

    In order to promote the inclusion of this prediction of dire consequence, water must react to its containment as a solid instead of a liquid and therefore will flood New york and LA.

    So: There is no consensus, it will take centuries for this to actually happen if it does and water must act like ice. Must truth be this inconvenient?

    Hi Auditor:

    I hate to be the guy saying "no conspiracy exists," but I do believe you guys are being DUPED by 'Cap And Trade' Disinformation Propaganda . . .

    A little geography lesson about the “West Antarctic Ice Sheet” includes the fact that this formation “is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves.” (Wiki). Ice generally floats on top of the water, because water in a frozen state has a larger mass (from expansion) and becomes less dense than the surrounding water. Therefore, the ice from this ice sheet is actually displacing ‘more’ water than if the ‘underwater mass’ melted; which would lower the sea levels rather than raise them.

    So, the ‘underwater’ WAIS is going to collapse! Wonderful. Okay, so where does the undersea ice formation go? :0) This entire story is Al Gore/New World Order Disinformation Propaganda for stooges without one brain in their heads! Here is a NewScientist.com article explaining how the Antarctic Ice IS GROWING:

    NewScientist.com Story

    Antarctic Sea Ice is ‘increasing’ every month of the year except January, but even these scientists want to speculate that this trend will somehow reverse, which means to me that they are also drinking some of the Al Gore/NWO Kool-aid. :0) Here is another Economic Times story that should help answer all the questions:

    [FONT=&quot]EconomicTimes.Indiatimes.com [/FONT]

    These scientists appear to have their feet firmly planted in reality, because (like Wiki said) the West Antarctic Ice Sheet is ‘a marine-based ice sheet, meaning that its bed lies well below sea level’ and melting ice that is underwater in NO WAY raises sea levels. Suppose you fill a tall glass with ice and then fill the glass to the top with water. When all of the ice melts in the glass (most is underwater), then the level of water in the glass will actually decrease; because water displaces less volume than ice.

    Then the idea that the east and west coasts of the USA would suffer rising sea levels, ‘more’ than the rest of the world, is more evidence that this ‘collapsing ice sheet’ nonsense is Global Warming Propaganda aimed at specific groups inside the USA itself. Even an idiot should realize that sea levels around the globe are affected by melting ice caps that must spread the water evenly around the world. Some New World Order Disinformation Lobby Group is trying to scare Americans into allowing ‘Cap And Trade’ taxation on carbon dioxide emissions, by creating the illusion of a crisis where NONE EXISTS.

    This doesn't seem reasonable to me. Is the Sea Level in these areas higher right now than the rest of the world?

    I have heard that there are "piles" of ocean water that occur due to anomolies in the gavitational field of the planet. Do these happen to exist at the sites where our largest coastal populations reside? If they do, then the water must already be higher than elsewwhere.

    If the water is currently at a level comparable to the rest of the world, what would cause it to pile up after the Ice Shelf melts in the year 2300?

    Don't bother Rock brain with inconvenient facts, he is all about fear mongering, one can not do that well when you keep coming along and telling everyone the REAL FACTS.

    Hey Sarge, note that I have posted from real scientists, and not wingnuts screwballs that people like you favor? Or does that even seep into whatever passes for your brain?

    Well, Code, were you to read the article, and further research the subject, you would see what the geophycists are basing their conclusions on.
