Do climate modelers include this?

It appears that the solar minimum we are experiencing has resulted in a significant increase in cosmic radiation reaching the earth.  There are two issues here:

1. If there is a 20-30% increase in cosmic radiation reaching the earth, then we should be seeing an increase in cloud cover (since cloud formation can be triggered by high-energy particles, which would increase the albedo of the earth and reflect more solar energy into space.  This would cool the earth.
2. Since the increase in cosmic radiation is due to a reduction in solar activity (wind and magnetism), this would also indicate that the earth is receiving less energy from the sun in the first place.  This would cool the earth.

So the question must be, did the climate modelers who predict doomsday include such an event?  What are the consequences?  If this is the reason the world has cooled since 1998 (in the face of rising CO2 levels), it would appear to me that the extraterrestrial influences can easily overwhelm anything that might be attributable to human activity.
