I'm not entirely sure what carbon dioxide levels were in the Jurassic period, but it is clear that what may have been good for dinosaurs will not prove so for human beings.
I very much doubt that there were 7 or 8 billion of any one species of dinosaur, and it is clear that their existence did not depend on agriculture.
Elsewhere in this group there is a discussion of Freeman Dyson, who held the view that climate change, although real, didn't matter all that much. A correspondent pointed out that in the sense that we will have to live with the consequences of climate change, whether we wish to do so or not, that Dyson was right.
Speaking for myself, it is very clear that because of the destruction of mountain glaciers, among other things, and important coastal cities, that the carrying capacity of the planet as a whole will fall precipitously. This will involve real human tragedy, including quite possibly suicidal wars.
If I'm wrong, so be it; I wish I could believe I was wrong.
I am not really interested in dinosaurs. They are extinct, and it is notable that there is a widely held theory that they were destroyed by instantaneous climate change brought on by an asteroid collision. It is notable that on a geological time scale, there isn't all that much difference between a 10 minute asteroid collision and a century and a half of injection of carbon into the atmosphere. The result may be the same.
I'm just not fond of mass extinctions. Call me old fashioned and a bit of a romantic, but that's how I feel.
