Maybe Not All Scientists Are To Be Trusted

Since you are too lazy and take the liberal tact of offering insults you might look up the thread in which Rock Doc and I disagreed about the purity of science and the objectivity of scientists. If you do not care to look it up then I do not have the time to lead you by the hand. Please go live your own life.

archer, he means this thread, starting on this page (21) and continuing to the next. An argument in which Rockdoc soundly beat him.

The show about how the great lakes were formed does an excellent job of covering the rebounding effect you note. In time, they predict that the great lakes will be nearly non-existent due to this rebound. The relatively small about of ice lost from the ice caps due to recent warming pales by many many orders of magnitude to the ice melted/rebound from the last ice age. I suspect the effect of melting ice caps is not distinguishable from the rebound effects from the last ice age. It is this type of obscuration and grasping at any information that can be [mis]used to make a case for the "changists" that turns me off. Isn't there enough evidence without stretching the truth and lessening credibility? I think so.

Sorry, I mis-spoke in my intro paragraph (I've been putting that post together for the last 2 hours and forgot to go back and check my brainstorming at the beginning) - the data is in the link I cited exactly as you stated. Yes, the amount of ice lost due to current warming is insignificant due to the rebound from the last ice age, but the earth is still rebounding from the last ice age, and will continue to change due to the lessening weight as the polar ice caps melt more. I was not trying to "grasp at any information", or "stretch the truth", but to gather my thoughts and re-find the data I'd previously read, nothing more. As it's spelled out as you said in the link I cited, you could've just said that I quoted it wrong, not tried to make it out that I'm twisting the data to fit my beliefs.

I didn't know that the Great Lakes are supposed to disappear due to rebounding, that's interesting. What show is it that you reference?

The correction for glacial isostatic adjustment (GIA) accounts for the fact that the ocean basins are getting slightly larger since the end of the last glacial cycle. GIA is not caused by current glacier melt, but by the rebound of the Earth from the several kilometer thick ice sheets that covered much of North America and Europe around 20,000 years ago. Mantle material is still moving from under the oceans into previously glaciated regions on land. The effect is that currently some land surfaces are rising and some ocean bottoms are falling relative to the center of the Earth (the center of the reference frame of the satellite altimeter). Averaged over the global ocean surface, the mean rate of sea level change due to GIA is independently estimated from models at -0.3 mm/yr (Peltier, 2002, 2009).

It is very interesting in many ways - from Niagara Falls to the large salt deposits under them. According to this show, the lakes are already much smaller due to the rebound that already took place. Thanks, I'll look for it.

I assumed the info about rebounding/ice caps was from one of your sources (I did not read them), and did not intend my comment to slight you, but your sources. I apologize. I could see how that could happen as my sources are long and boring and I'm probably the only one who reads them, no worries, apology accepted, we're all good! My apologies to you if I came off as snappy, it was not my emotional state nor my intention.

In regards to the ice caps melting - unless the Arctic ocean was frozen to the bottom - ice melting there is not affecting rebounding.Yes, the Arctic is not causing any rebounding (in an attempt to shorten my post, I didn't elaborate a 2nd time that rebounding due to glacier melt would be occurring mainly because of Antarctica and Greenland, it's there in my first post somewhere where I stated "at or near the polar regions")
