      Abstract
      Mass loss from the West Antarctic ice shelves and glaciers has been linked to basal melt by ocean heat flux. The Totten Ice Shelf in East Antarctica, which buttresses a marine-based ice sheet with a volume equivalent to at least 3.5 m of global sea-level rise, also experiences rapid basal melt, but the role of ocean forcing was not known because of a lack of observations near the ice shelf. Observations from the Totten calving front confirm that (0.22 ± 0.07) × 106 m3 s−1 of warm water enters the cavity through a newly discovered deep channel. The ocean heat transport into the cavity is sufficient to support the large basal melt rates inferred from glaciological observations. Change in ocean heat flux is a plausible physical mechanism to explain past and projected changes in this sector of the East Antarctic Ice Sheet and its contribution to sea level.

        Chooky,

        The dark secrets are here as to CIA activities all around the world thanks to Obama with Shonkey’s help CIA are operating under secret orders right here in NZ now.

        Obama’s global terror campaign is not only dependent upon his drone assassination program, but increasingly it has come to rely upon the deployment of Special Operations forces in countries all over the world, reportedly between 70 and 120 countries at any one time.

        The evidence for rapid climate change is compelling:

        Sea level rise

        Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century

    Climate change: How do we know?

    Now the average heavy freight truck has 34 tyres and produces 100 times more tyre/brake dust and exhaust soot pollution than one car. (NIWA statistics)
    Latest scientific evidence shows these forms of black dust are accelerating the melting of arctic ice faster than previously thought.
    This is increasing sea level rise far more quickly than before.
    This is why we need rail freight transport.
    This is not time to plan more truck routes.
    The proof is here – Quote; “Global sea level rose about 17 centimeters (6.7 inches) in the last century.
    The rate in the last decade, however, is nearly double that of the last century.We don’t need more roads for trucks we need a return of rail services.

    We need to manage our transport to lower the air pollution that will increase Antarctic ice melt.

    • scary!…of course we need rail and less trucks on the roads…which political party supports this the most? NZF or Greens?

      • Chooky,

        NZ First has the most comprehensive rail restoration policy to build new rail lines and complete the rail system to make it work efficiently.

        For instance they have a plan to complete the Auckland to Napier (east coast link) which was planned to begin building in 1939 but the war exhausted the funds.

        But we need a east coast rail route as even this lacklustre Government recognises that in the South island a east coast rail network is also needed.

        One from Picton to Dunedin, as we see they are now pouring in 2 Billion to fix both road and rail immeadiately.

        So do we need this money spent in the North Island, and NZ First recognise this urgent need fully.

        So NZ First is the best policy, and the Greens second place.

        Hopefully the Greens will catch on to NZ First and join them in their herculean efforts to finally fix our uncompleted national rail system so it can compete with road freight again.
