I can't explain that, nor do I understand why in the late Ordovician period
450 million years ago there was a huge 4400 ppm of CO2 in the atmosphere
verses 380 today, and yet the world was in the grip of a very severe ice
age. Apparently the climate dynamics of this planet is complicated and the
link between global warming and CO2 is not as straightforward as some would
have us believe.
