Humans stop emitting all CO2 today, it warms for 20 years, then stable for 1000 years.
Very accurate predictions here champ! Let's compare your fairy tale to the empirical data:
WOW!!! We must have stopped emitting all CO2 over 50 years ago, because the atmospheric temperature has stabilised for more than 30 years!!! We are actually .02 degrees LOWER than the average. The 1000 year slow cooling phase has possibly started already.
Your fairy tale came true!!!
Oops, except for the fact us humans have not reduced all our CO2 emissions to zero.
So close, but no cigar.
But lest I be accused of cherry picking, let's see how your 20 year lag of temp to CO2 model works, then the 1000 year stabilisation afterwards. 550 million years should be long enough to see the trend, huh?
Sorry dude, can't see it, still no cigar.
But wait, is that CO2 levels peaking at 7000 parts per million, then lowering, then rising again to 3000 parts per million, then lowering, er naturally? I thought you guys said that we had to "Save the Planet" by avoiding the catastrophic 500 parts per million???
The Planet's still here, in my black and white reality anyway, in your colourful version it may have been destroyed and this is all another fairy tale.
Gee, and average global temps recently increased to 22 degrees quite naturally, and then they reduced to 12 degrees quite naturally, now they are gently rising out of the last little ice age, er naturally?
Yeh, I think I'll stick with reality mate.
But you guys keep the fairy tales coming, I like stories that begin with once upon a time.
