A noted geologist who coauthored the New York Times bestseller Sugar Busters has turned his attention to convincing Congress that carbon dioxide emissions are good for Earth and don't cause global warming. Leighton Steward is on Capitol Hill this week armed with studies and his book Fire, Ice and Paradise in a bid to show senators working on the energy bill that the carbon dioxide cap-and-trade scheme could actually hurt the environment by reducing CO2 levels.
"I'm trying to kill the whole thing," he says. "We are tilting at windmills." He is meeting with several GOP lawmakers and has plans to meet with some Democrats later this week.
Much of the global warming debate has focused on reducing CO2 emissions because it is thought that the greenhouse gas produced mostly from fossil fuels is warming the planet. But Steward, who once believed CO2 caused global warming, is trying to fight that with a mountain of studies and scientific evidence that suggest CO2 is not the cause for warming. What's more, he says CO2 levels are so low that more, not less, is needed to sustain and expand plant growth.
Trying to debunk theories that higher CO2 levels cause warming, he cites studies that show CO2 levels following temperature spikes, prompting him to back other scientists who say that global warming is caused by solar activity.
