Not only is global warming real, but the cost of preventing it  would be small, and even beneficial.  So say many environmental  leaders who believe we could easily meet world energy demand  without relying on fossil fuels.  But now comes a major new report  in Science magazine which ices this overheated claim.  According to  the report, technologies simply do not exist at the present time  which could meet the world’s growing energy consumption without  emissions of carbon dioxide.  Indeed, with 85 percent of the  world’s current 12 trillion watts now supplied by fossil fuels, the  authors suggest that only revolutionary changes in energy  production, distribution, and storage could ever hope to phase out  our current energy sources.
