    […] July 22nd, 2007 at 12:29 pm (Multimedia) This video was complied by UCAR and the National Center for Atmospheric Research. It shows the summer extent of sea ice in the arctic from 1990 to the present, and projects to 2049. For a better understanding of what this means see this video explanation. […]

    This guys explanation that ‘sea ice will not add to any sea leval change’ is a LIE! He did not include the thermal expansion factor, which WILL add to a rise in sea level.

    The UN IPCC has concluded, taking into account ALL factors that a MINIMUM sea level rise of FIVE(5) meters is inevitable before 2040. And a recent British govenment study, exposed by author George Monbiot in the last month, has come to the sobering realization that the UN IPCC paper’s worst case scenario is unrealisticly optimistic, and does not take into account that the Greenland Icesheet and the Antarctic icesheet will undergo a catasrophic disintegration, and will most probably happen before 2012, leading to a 30 -40 metre change in sea levels.

    For those proponents of expanded economic trade, using routes over the soon to be ice-free North Pole, I ask,where will your ships find port? New York, London, Los Angeles, Sydney, Hong Kong, Halifax, Vancouver, Seattle, Marseilles… all existing port cites will be UNDERWATER. Your economic futures are at the mercies of a rising tide. Your lives and livelyhoods are under a threat that will sweep you, literally, into the sea.

    For those of us who haven’t switched to the metric system that would be a 100 – 130 foot sea level rise by 2012. And because of how Antarctica and Greenland would contribute to the sea level rise it would be a rapid increase. In fact, it would strongly resemble a storm surge in general pattern. But predicting this kind of thing with any precision is difficult.
