On the other hand, decreased magnetic activity from a more quiescent sun can result in increased cloud nucleation by galactic cosmic radiation normally reduced by an active sun.
Precisely the problem. We have experienced more moisture in the US then typical from this La Nina. Bastardi also thinks it got colder then normal in the US for a first year La Nina. We normally do not see freezing rain in Brownsville Texas for example after a La Nina. So we are colder and wetter. Exactly the opposite of what the AGW crowd predicted. Now the El Nino of 2009/2010 was a surprise for the true scientists, but that is how you tell a true scientist from a political scientist. The natural world still amazes the true scientist. The political scientist just doubles down and compounds their initial error.
