Feel the environmental heat

Rising levels of the greenhouse gas may not be stabilized unless the global economy collapses or until we are building one nuclear power station every day. Tim Garrett, associate professor of atmospheric sciences at the University of Utah suggests that energy conservation will not be enough to ward off potentially catastrophic changes in the planet's climate caused by anthropogenic carbon emissions. "Stabilization of carbon dioxide emissions at current rates will require approximately 300 gigawatts of new non-carbon-dioxide-emitting power production capacity annually - approximately one new nuclear power plant (or equivalent) per day," Garrett says. "Physically, there are no other options without killing the economy."
