the geologic record provides us with abundant evidence for such perpetual natural climate variability, from icecaps reaching almost to the equator to none at all, even at the poles.

based on this and estimated plant-gas exchange rates and global surface temperatures, the climate sensitivity was calculated to be +3 °c when co2 levels doubled, compared to 7° following the formation of ice at the poles.
