You do know that the dinosaurs, with their big lungs, were suckin' back
about 6.5 times (2300 ppm) the CO2 that exists today, when they were
pounding around on the Pangaea supercontinent, 200 million years ago?
That was 150 million years after the Mississippian Epoch for christ sakes!

This was before all of the fossil fuels that existed 2 centuries ago
were formed from biomass. Also at this time, there were no continents at
the poles, making the world freer of ice and reflecting less sunlight,
absorbing more.


HC's were formed during the Devonian Period (450 million years ago).
Coal was formed during the Carboniferous Period (specifically during the
Pennsylvanian Epoch, 310 million years).

Have you heard of 'Angle Of Incident' re the sun? That's one reason why
the pole areas are colder on Earth... and Mars.






Plus there is a feedback from CO2 being less soluble in
warmer oceans. Sea level was something like 600 feet higher then than
now.

Show me the 'feedback'.
