Posted Sun May 30 2010: from New Scientist:
Did early hunters cause climate change? http://apocadocs.com/s.pl?1275219730
IT'S not just for the last century that humans have been messing up the climate. It may have been going on for thousands of years. When hunters arrived in North America and drove mammoths and other large mammals to extinction, the methane balance of the atmosphere could have changed as a result, triggering the global cool spell that followed. The large grazing animals would have produced copious amounts of methane, a potent greenhouse gas, from their digestive systems. They vanished about 13,000 years ago.... "It is conceivable that this drop in methane contributed to the Younger Dryas cooling episode," says Smith. This would mean humans have been changing global climate since well before the dawn of civilisation
