So doesn’t that say something about the mere presence of 400ppm CO2?
NBC News reports:
The last time concentrations of the greenhouse gas carbon dioxide were as high as they are today, big chunks of the seemingly stable East Antarctic ice sheet melted and helped raise global sea levels more than 65 feet higher than they are now, a new study suggests.
I love it when you talk dirty….
I was waiting for the 2.5 million-years-ago sledge with the rich Corinthian leather harness. It lost half its clams value as soon as my dog pulled it off the lot.
You didn’t get your SLEDGE and snowshoes till a few years after that!!!
now, one must recall that carbon dioxide is present in the oceans and when the world warms, carbon dioxide is released from that sink hole, some of which is immense—like the deeps that go to tens of thousands of feet.
and when ice ages were present ocean levels went down since there is a definable amount of water on the earth—I think pretty much with a few provisos like water can be tied up in chemical brews so some might say its sequestered. but who’s counting?
did you know that the carbon dioxide content of the atmosphere has been over 5000 PPM in the distant past when things were lush and green and t rex roamed the swampy lands?

Hookay, how long had global warming been going on when the vast glaciers were completely melted? And what brought on the kind of cooling that caused them to form again? And where did the 400ppm come from? I didn’t get my car until a few years after that…
