Hacking the planet: The only climate solution left... http://apocadocs.com/s.pl?1235594338
Previously, the idea of tweaking the climate in this way was anathema to most scientists. Apart from the technical challenges and environmental risks, many argued that endorsing the concept might scupper international negotiations for a post-Kyoto protocol to reduce global emissions. But it's becoming clear that moves to cut global carbon emissions are too little and too late for us avoid the worst effects of climate change. "There is a worrying sense that negotiations won't lead anywhere or lead to enough," says Lenton. "We can't change the world that fast," says Peter Liss, who is scientific adviser to the UK parliamentary committee investigating geoengineering. Extraordinary measures may now be the only way of saving vulnerable ecosystems such as Arctic sea ice.... What's more, geoengineering could turn out to be relatively cheap. Early estimates suggest some schemes could cost a few billion dollars, small change compared to the cost of slashing emissions - estimated by former World Bank chief economist Nicholas Stern to be at least 1 per of global GDP per year. In his testimony to the UK politicians last year, John Latham of the National Center for Atmospheric Research in Boulder, Colorado, argued that all of the above reasons make it "irresponsible" not to examine geoengineering.
