'Estimates of the rate of ice loss from Greenland and West Antarctica, one of the most worrying questions in the global warming debate, should be halved, according to Dutch and US scientists.Read the whole piece and then try and see if the BBC are reporting this story... I can't find it on their website; why?
In the last two years, several teams have estimated Greenland is shedding roughly 230 gigatonnes of ice, or 230 billion tonnes, per year and West Antarctica around 132 gigatonnes annually.
Together, that would account for more than half of the annual three-millimetre (0.2 inch) yearly rise in sea levels, a pace that compares dramatically with 1.8mm (0.07 inches) annually in the early 1960s.
But, according to the new study, published in the September issue of the journal Nature Geoscience, the ice estimates fail to correct for a phenomenon known as glacial isostatic adjustment.
This is the term for the rebounding of Earth's crust following the last Ice Age.
Glaciers that were kilometers (miles) thick smothered Antarctica and most of the northern hemisphere for tens of thousands of years, compressing the elastic crust beneath it with their titanic weight.
When the glaciers started to retreat around 20,000 years ago, the crust started to rebound, and is still doing so.'
I am not a sheep, I have my own mind
I have had enough of being told what and how to think
Whilst we are still allowed the remnants of free speech,
I will speak out.
I also reserve the right to discuss less controversial matters should I feel the urge.
