      --- Antarctic Ice Shelves:
      9 December 2003
      Antarctic Glaciers Speed Up: Scientists at NSIDC have found that glaciers
      around the area of
      the Larsen B Ice Shelf accelerated immediately after it collapsed early
      in 2002, and are still
      speeding up.

      --- Arctic climate is showing signs of rapid change:
      Changes beginning in the 1970s and 1980s include:
      warmer winters and springs over North America and Eurasia
      warmer air over the central Arctic Ocean
      warming in the Arctic Ocean at 200 to 900 meters depth
      reductions in sea ice and snow extent
      increases in terrestrial precipitation
      warming permafrost in Alaska and Russia
      increased plant growth
      northward migration of the treeline
      increased heat and moisture advection into the
      Greenland and Barents Sea regions
      increase in the temperature of the Atlantic water flowing
      into the Arctic Ocean
      thinning of multiyear arctic sea ice,
      negative mass balance of glaciers.

        Hello,

        All of these are features of climate change, though there is some
        debate as to how fast the heating process is occurring, not to
        mention how much altered micro-climate patterns might either slow or
        speed up the process; in other words, the northern reaches of Europe
        will certain endure a temporary cooling as a result of already
        changing ocean currents in the Atlantic, but how long this cooling
        lasts is anyone's guess at this point. Likely, though, the influx of
        fresh water runoff from the eastern seaboard will speed up the
        process as the density of ocean waters change and thus affect those
        much-needed warm currents. Certainly the increase in precipitation
        will continue to contribute to the freshwater influx.. so it's like
        a new climate engine is being built against our collective will...
