Controversial study says ancient people started global warming

Researchers at the University of Virginia and the University of Maryland-Baltimore County have a controversial idea: "Ancient man may have started global warming through massive deforestation and burning that could have permanently altered the Earth's climate." (CNN)

All the slashing and burning over the ages, since people started farming, would have "spewed enormous amounts of greenhouse gasses into the atmosphere and warmed the planet."

Of course, the theory isn't without opponents. "There are actually studies showing if you cut down forests for farmland, you actually cool the planet, because of the glare from the cleared land," says one critic.

I started pound360 to channel my obsession with vitamins, running and the five senses. Eventually, I got bored focusing on all that stuff, so I came back from a one month hiatus in May of 2007 (one year after launching Pound360) and broadened my mumblings here to include all science.
