BERKELEY, California - Climate models that predict the Earth's average temperature could rise as much as 10 degrees by the end of the century may have underestimated the increase by as much as four degrees.A year and a bit ago I wrote that the prospect of a positive-feedback cycle was making me reconsider my opposition to nuclear power, and I keep waffling on this. I guess I need another hit of good, pure, uncut data from actual renewables performance before I abandon nuclear entirely.
New research at UC Berkeley and Lawrence Berkeley Laboratory suggests that as carbon dioxide emissions heat the globe, hotter oceans and soils will release stored carbon dioxide, which will in turn kick up the thermostat an extra notch.
"We've probably underestimated the problem," said UC Berkeley ecologist John Harte....
"It's a vicious cycle where more warming causes more greenhouse gas emissions, and more greenhouse gas emissions cause more warming," Torn said. "That could have serious consequences both for human populations and biodiversity."
