Hi all, Have you seen this? Best case for SRM in Arctic I've seen!
Inventor Nathan Myhrvold describes "space hose" for getting aerosols into stratosphere - and he's done the modelling to show it could be used at the Arctic, to cool whole hemisphere, without disrupting weather (see about 9 minutes in). "Cooling the Arctic shuts of a whole lot of tipping points." It shows incredible promise, but governments aren't running to him - so far. http://www.cnn.com/video/#/video/podcasts/fareedzakaria/site/2009/12/20/gps.podcast.12.20.cnn "Suppressing the only technology that could get us out of this pickle..." would be plain silly. He argues (as nobody I've seen to argue before), that even emissions reduction to zero overnight, would not solve the problem of global warming, because about 20% CO2 stays in atmosphere for thousands of years. "Geoengineering has to be part of the debate". "We have to examine the options". "You can't rule these things out."
