Carbon dioxide during Phanerozoic period, averaged, for the past 500+ million years. en.wikipedia.org This page also gives a graph of relative warmth during the period. We're pretty ice cold. en.wikipedia.org As a very unscientific observation from these crude graphs, it's interesting that biodiversity appears to jump during the warm periods. en.wikipedia.org

Not many humans, but lots of fauna. You are correct though, that was the big carbon sequestering period (except for the abiotic oil crowd). I wonder how the destruction of forests has effected greenhouse gases ... Can only get worse as Brazil continues to ramp up sugar cane for ethanol production. There goes a lot of sequestered carbon. Then there are the peat bogs... We have a huge 'un' sequestering problem notwithstanding fossil fuels.. Maybe every roof should be flat with a lawn ? Hopefully we won't realise 100 years from now that we were going about it back asswards... I'm more concerned with unbreathable air, poisoned waters etc.. Does anyone really know the effects of the climate warming beyond glacial melting and rising sea levels. I wouldn't buy real estate in the Netherlands or Bangladesh... Besides Nature does not believe in a 'status quo' Roy
