Hmm, two threads about this. From the other one:
What happened to global warming? It's on its way, as soon as our CO2 levels cross over into the red the scale will suddenly be tipped and the polar
caps will melt.
We have not seen significant increases in temperature because we have not yet reached the critical level of atmospheric CO2, which is about 450 parts
per million. Were are just under 400 ppm.
A brand new core sample extending 20 million years has recently been pulled from the ocean floors showing us that at CO2 levels of 400-450 there were
no polar ice-caps and sea levels were 30-40 meters higher.
What all of our international climate debates have garnered us is a tentatively accepted CO2 level of 450 ppm. This after an initial fluctuation to
over 500 which should settle at 450.
Scary stuff.
What's happened to Global Warming? It's teetering on the edge, that's what.
