"David" provides a description of carbon dioxide levels and global warming that is about as good as any I've seen from any British scientist, or from Al Gore. I wonder where those high levels of carbon dioxide came from during the Age of the Dinosaurs? It certainly was not man-made. (By the way, as reported earlier, global warming in the Middle Ages allowed the Vikings to settle [and name] "Greenland."
I can't make this stuff up.
