A solid link, please..." Well, I don't know. What warming period in the past involved widespread burning of fossil fuels? So there really aren't any that are comparable. The closest would be some of the very early ones when we had snowball Earth. With very little photosynthetic activity, the CO2 levels would have risen, leading to the Tyndall effect warming the Earth. But there isn't much in the way of fossil evidence from those days. "So here we go, you do indeed claim, that CO2 increases had a positive feedback on past cycles (800 years before)?" Well, duh. I've only stated that dozens of times. So quit pretending this is news to you. "Makes you quite a (co-)scientist, right? " Not really. I just tend to go along with scientific consensuses because I don't really have the time to educate myself to the level required to have a totally independent opinion on every issue. How many years have you been studying this issue? Published any papers? Done original research in the area? "Now, that would be first time in Earth history, that a CO2 hike proceeds a period of GW - and possibly even causes it... migod, you ARE a pioneer, like Newton, right?" Nonsense. You are the one swimming against the tide of the bulk of the scientists in the field. You are the one claiming the mantle of Newton, not I. I am not claiming that the majority of scientists in a particular field are trying to pull a scam, you are. I can only hope you have the credentials to back such an extraordinary claim. Because, otherwise, I have to assume you are just a crank trying to peddle your perpetual motion machine.
