Max – A valiant effort on your part but totally wasted on those who are irrevocably committed to denial of global warming or its product climate change and, to be charitable, have little knowledge of climate science or its inference.

The article presents a ludicrous analogy between the present and the past several hundred million years or so. This has nothing to do with the plight facing humans to-day and the comparison is spurious, as the author knows full well.

Homo sapiens as a species was certainly not about – or threatened by climate change as long as 100,000 years ago. It is now, increasingly so – dangerously so. What Dr Aitkin does know is a lot about Political Science – but physics, global warming or its causes and effects, sadly no.

For god sake Agnostic, & the rest of you fools, go read JoNova's blog for just 5 minutes, & try to understand which way is up.

To you gravy train riders, watch out, the planet has you in it's sights. The whole scam is about to die at it's hands.

Surrounded by you Genii (Is that the plural of genius?) can any of you explain the Ice Age?
See I have heard it was everywhere but logically it must have only happened at the Northern hemisphere.
Now that finished 15,000 years ago and is the basis for the great flood of so many religions as when the ice melted over 50 years the seas rose up by many many metres.
Lets here it from you.

No it can't be explained. The ice in the north made the south lighter and the planet tipped over with the frozen seas unable to expand and pushed Antarctic glaciers uphill.

JBoyer, you're understanding of anthropology and the origins of flood myths is as misguided as your denial of climate science. Most early cities developed near the food sources: rivers. These rivers flooded. Regularly. So the Enuma Elis, Epic of Gilgamesh, Genesis and even Egyptian myths all have water and floods of some sort.

But that's irrelevant to this discussion.

The earth's earlier *natural* volcanic high CO2 events were catastrophic. But back then, the sun was 2 to 3% cooler. Now? High CO2 events could be absolutely devastating given the sun is hotter! Did the author of this article bother to spell that out? No. That's Pathetic. Embarrassing. Incriminating.

Max Green you never read what I wrote or at least did not understand it and the answer given by nickname did not make any sense.
Explain the Ice ages as there were many and I might think you know something.
Blow hard buddy blow hard!
