Its nice to see people going to their Republican representatives and telling them to get real, but I would have hoped the crowds were larger and the instances of activism of this sort more common. This is from the DCCC:

On the face of it, it is impossible. Cosmic rays vary over time, and climate varies over time, and the two variations do not correspond. Global temperature has been going up over the last century, in correspondence with increased of atmospheric CO2, and this makes sense because the physics says that CO2 is a greenhouse gas, and this whole global warming thing is a greenhouse effect. Bringing cosmic rays into the situation seems both unnecessary and difficult to do.
But it turns out that there is a cosmic ray – climate connection which is interesting if it turns out to be true. But this connection is NOT any kind of link between cosmic rays and global warming. Cosmic rays do not cause global warming. Did you read that last sentence? OK, good.
