JJ JJ11: So who or what put the CO2 in the atmosphere before or during dinosaurs? Why isn’t that elevated level considered the “natural state” that earth is trying to move back too after somehow the dinosaurs’ existence changed it? Perhaps global warming adherents are trying to work against nature? Personally, I’m all for a few degrees warmer temps in the northern states where I live - so maybe I should buy a gas guzzling car? Seriously though, I’m not arrogant enough to believe that humankind is able to alter the earth’s natural climate cycles - to suit its needs.
