Nearly two dozen research teams collaborated to study polar ice sheets in Greenland and Antarctica and discovered definitively that they have added 11mm to global sea levels since 1992, melting ever more quickly. Read full article

    That ice is drifting towards rgenweener so it must be theirs

    Phew!!!!
    After seeing Mr Brown and his friends safely off to the coast,
    i too fear, I may have just added a few more millimeters to the sea level.
    maybe argentina could haul it in and stake a claim on that!

    Lead author of the research, Professor Andrew Shepherd of Leeds University....noted that the figure is in line with climate change predictions. Of course it would have to be , although computer models cannot predict, they can only project scenarios and they are reliant on the information fed to them.

    “4000 years history of Greenland surface temperature”

    They note that ”the current decadal average surface temperature at the summit is as warm as in the 1930s-1940s, and there was another similarly warm period in the 1140s (Medieval Warm Period),“ indicating that ”the present decade is not outside the envelope of variability of the last 1000 years.“ In fact they say that ”excluding the last millennium,“ there were fully ”72 decades warmer than the present one, in which mean temperatures were 1.0 to 1.5°C warmer,“ and that during two centennial intervals, average temperatures ”were nearly 1.0°C warmer than the present decade.“

    Also, At WUWT: ”New proposal from NASA JPL admits to “spurious” errors in current satellite based sea level and ice altimetry, calls for new space platform to fix the problem.“

    Anthony Watts comments:
    ”This recent internal PowerPoint presentation (obtained from an insider) from NASA JPL touts the new GRASP (Geodetic Reference Antenna in Space) satellite project. I’d say it is more than a bit of a bombshell because the whole purpose of this new mission is to “fix” other mission data that apparently never had a stable enough reference for the measurements being made. This promises to rewrite what we know about sea level rise and acceleration, ice extent and ice volume loss measured from space.”

    Back to the drawing board.....

    Or to put it simpler, the human foot print did not cause the last ice age and I think we can all agree, that was definate climate change.

    If the ice is melting faster that would facilitate further colonization of Argentines into Argentine Antarctica, and perhaps we could expand our claim area east and west a bit to offset the ice loss.
