The science of Global Warming reached consensus in Neandertal times. In fact, it may even have been a major factor in Neandertal extinction. My Neandertal ancestors, jolly chaps though they undoubtedly were, may have sweated very heavily in their fur garments, and thus possibly were not as attractive to the newcomers in the mating and dating scene as they might have been.
I am moving briskly on and seeking federal grants to clone the Moa and the Dodo and repaint my 240D before the oceans rise.
