YouTube - Berkeley Prof. Richard Muller on Copenhagen and Global Warming
[ "(The IPCC is) very clear about the fact that cloud cover is the biggest uncertainty, and if cloud cover were to increase by 2% in the next 50 years, then we wouldn't have global warming."]
If the theory that cosmic rays increase cloud development that 2% should be no problem. With the lower solar output more cosmic rays are hitting the Earth. Between that and the AMO and PDO both in cooling mode I'd say that warming will be the least of our worries for some time to come.
