(quote)Coffeeman: I have heard there is volcanic activity under the polar caps and that is part of the polar ice melting. Also, the antartic is gaining ice. No one mentions that, so maybe I read wrong.
400,000 yrs ago CO2 levels were 10 or 20 times higher than today. Wonder what kind of cars (unquote)

States that one area of antarctica is gaining ice but is being offset by losses elsewhere and even that gain is not expected to continue.
Evidence of a Warming Earth - The Woods Hole Research Center
Gives a chart showing CO2 levels fluctuating up and down over the past 400,000 years but a sudden huge rise in our times. 400,000 years ago per that it was nowhere near current levels:
I hadn't heard that about the volcanoes. I think I will go looking - sounds interesting.

I shudder every time this subject comes up. I do not understand why anyone would make a reasoned decision about anything by watching a movie no matter if it is anti or pro. There is whole world of good information out there on the 'net and sources can be found that do not have an ax to grind.

Eddie: The "dinosaurs" and other organic debris does not 'make its way down'. It dies, sinks into the mud or is covered by mud in floods or dirt in landslides, more is added on top, more yet, etc. and some of the buried remains become part of tectonic plates that subduct under others.
This planet is billions of years old and there is plenty of time for things that seem impossible to happen.
