Antarctic ice really is collapsing, oceans' rise unstoppable


Two groups of scientists report that large parts of the ice sheet in West Antarctica have started to collapse. Global warming is accelerating the pace, they said at a NASA press conference today. They believe the rise of sea levels is unstoppable. NASA's Thomas P. Wagner: "This is really happening. There’s nothing to stop it now. But you are still limited by the physics of how fast the ice can flow.”

  1. But my uncle sent me a chain email saying that the ice was actually expanding.

    Who am I going to believe, my uncle or some "scientists." My uncle let me ride his minibike when I was 8...

    Am I the only one confused by the term "West Antarctica"?

  3. Sea ice has a relatively small impact on water levels, because the volume of water displaced by an iceberg is equivalent to the volume of liquid water produced when it melts. (It's actually more complicated than that, but you get the idea.) Land ice is the real killer for sea-level change, because it's not displacing any water at all until it melts.

    Edit: More specifically: If you fill a glass with tap water and ice cubes, and then wait for the ice cubes to melt, the water level will not change at all. If you use seawater instead of tap it will change a bit, because ice is fresh water, which has a different volume than seawater. If you fill a glass with tap water, and then put a funnel on top of the glass and fill it with ice cubes, the glass will overflow all over the place as the ice melts.

  4. please move closer to the ocean.

  5. Every notice how pretty much everybody who has visited this "Antarctica" place the chicken littles are so freaked about is either a GRANT HUNGRY SCIENTIST or a GOVERNMENT WORKER????


    And if that doesn't convince you how about http://HIPPIESHATESCIENCE.BLOGSPOT.COM/ClimateScientistsPreachCOMMUNISM.html
