I"m just absolutely stunned. According to this article, there was a time 41 million years ago that was was more carbon footprint in the atmosphere than there is now. I thought the only "global warming event" that has ever occurred on planet Earth began in 1790, at least that is what the "end of the world religious fanatics" in the Church of Global Warming have been preaching to us. Hey 1790 Yor_On, we need your scientific-religious expertise to straighten out these nutcases about carbon footprint data, & that only "man" can create bouts of Global Warming for which the Church of Global Warming proclaims the date of 1790 marking the beginning of the end of the world (I thought Jerry Falwell was dead, but I guess he"s been resurrected in the Church of Global Warming. Why can"t these "end of the world" nutcases just stay in their graves?).
