Since this Rappley from the british Antarctic Survey has been featured on Lateline giving a different view of one of the models.

Sharples report to the Tasmanian Government on sea level rise by 2100, based on the IPCC Third Assessment Report, was between 22 and 88cm.

Current ice melt rates on the West Antarctic Ice Sheet, one of 3 in the Antarctic, leads to a total of 1.5m sea level rise by 2100.

This also excludes the Greenland contribution or that of other land based Ice such as on Iceland, in the tundra and even in New Zealand.

So, with just this addditional melting the business as usual path is taking us to between 7 times and almost double the 5 year old predictions.

The goephysical implications in the reduction of the weight of ice [~30Billion tons total now] on the antarctic plate from this degree of change are not stated by the glaciologist.

However, W McQuire is of the view, evidenced from some pleological research, that changes in sea level could influence volcanic activity. Tectonic plate movement may also be affexcted.

Such additional activity could assist in restoring a balance by lowering air temperature.
