I'm guessing that the Arctic nor the Antarctic won't be melting away any time soon. Who could have guessed that in 2008 when this thread started?
The scientists in the IPCC?

I am the first to admit that I am not familiar with this science, but how do you reconstruct ice area back all the way to 600AD? I cannot figure out how I could trust this graph. I can see extrapolation back for "awhile", but 1400 years !......It remained basically unchanged for the last 2,000 years until just recently.

As Ewing and Donn read the evidence, an Ice Age will result from a slow warming and rising of the ocean that is now taking place. They believe that this ocean flood — which may submerge large coastal areas of the eastern United States and western Europe — is going to melt the ice sheet which has covered the Arctic Ocean through all recorded history. Calculations based on the independent observations of other scientists indicate this melting could begin, within roughly one hundred years.
It is this melting of Arctic ice which Ewing and Donn believe will set off another Ice Age on earth. They predict that it will cause great snows to fall in the north — perennial unmelting snows which the world has not seen since the last Ice Age thousands of years ago. These snows will make the Arctic glaciers grow again, until their towering height forces them forward. The advance south will be slow, but if it follows the route of previous ice ages, it will encase in ice large parts of North America and Europe. It would, of course, take many centuries for that wall of ice to reach New York and Chicago, London and Paris. But its coming is an inevitable consequence of the cycle which Ewing and Donn believe is now taking place.
The coming of another Ice Age is an event serious scientists have never been able to predict from observable Earth phenomena. For until Ewing and Donn postulated their new Theory of Ice Ages (it was first published in Science in June 1956 and a second report appeared in May 1958) the very nature of the problem seemed to defy the kind of scientific understanding which makes prediction possible.
Scientists know that the glaciers which stand quiet in the Arctic today once covered America with a wall of ice up to two miles thick — its southern boundary extending from Long Island across New York, Pennsylvania, Ohio, Illinois, Wisconsin, Iowa, and the Dakotas to the Missouri River, with extensions into the western mountain country . . . that it covered northern Europe, England, large parts of France and Germany . . . that it created the Great Lakes, the Hudson and St. Lawrence Rivers . . . that it moved mountains, crashed down forests, destroyed whole species of life.

I am a casual reader on this topic, and have no defensible position of my own, but THEU, your comments display a pretty basic misunderstanding about what goes on in science. You seem to think scientists all agree on a "theory," and then spend their time attempting to prove it. One makes his/her bones in science by falsifying/negating/disproving the other guys hypothesis. When you can actually disprove a theory (that is, a former hypothesis that is now a well-substantiated, unifying explanation for a set of verified, proven hypotheses), you are a big time star. This is what scientists try to do. They don't conspire to prop up "theories" that can be discredited (but for the posited conspiracy) - they work their asses off to destroy theories.recreations, by scientists attempting to prove a theory. I simply don't trust that.
A great deal of valuable work is supported by grants and other funding models — work that has yielded real benefits to humanity, and might never have been done otherwise. You might find it worthwhile to spend some time educating yourself on the issue before criticizing it.I am suspicious of anyone that has to release and publish findings to get grants and funds to get paid, if you aren't suspicious then well you are just well......fill in the blank....
