On Why Global Cooling is Far More Dangerous than Global Warming

This one is so elemental that it's embarrassing. What happens during intense episodes of global cooling (glaciations or ice ages, if you prefer), people? Yeah, that's right, a little something called massive ice sheets covering entire damned continents, food shortages, desertification/long droughts, and, yes, mass extinctions (the worst mass extinction happened 252 million years ago and was more than likely caused by basalt volcanoes that triggered major cooling).......................................................................................Compare this to episodes of global warming in which there has invariably been an explosion of life (the Cambrian explosion of 520 million years ago and even the most recent interglacial in which homo sapiens evolved, for example) and you really do have to wonder about the sanity of these alarmists.......................................................................................P.S. Researchers at Cal Poly have also linked the late Ordovician mass extinction to global cooling and that is hardly surprising, either - http://www.sciguru.com/newsitem/13576/What-Triggers-Mass-Extinction-Caltech-researchers-say-habitat-loss-and-tropical-cooling-were-blame
