During the Cretaceous Period ('K') the earth's tectonic plates were more or less in positions similar to what they were today, and there was an
hothouse condition (for earth anyway). There was no ice at the poles, sea levels were high, temperature was high, and the concentration of Carbon
Dioxid (CO2) was high.
IOW, this is what happens to north america in a greenhouse condition:
This is what happens to the world at large:
Unfortunately, there wouldn't be these guys swimming over the ocean floor (nebraska, wyomming, etc), if it happens again
