Actually it is not uncharted. It is the type which was perfectly adapted to
the dinosaurs.

Hmmm. Unless the dinosaurs were technologically much more advanced than we
often assume (and, if so, they've certainly hidden the fact quite well,
though David Icke might argue otherwise), I suspect that it was the
dinosaurs that were well adapted to the prevailing climate, rather than vice
versa.

Yes, and we are well adapted to a climate produced by 280 ppm of CO2, as is our agricultural systems, and our infrastructure. At the time of the dinosaurs central north American continent was under the sea.
