Here's the first part of another post by my nemesis, "Dahun"

"The most convincing argument yet, supporting a strong impact of the sun’s activity on climate change, is a direct connection between cloud coverage and cosmic rays, discovered by H. Svensmark and E. Friis-Christensen [111] in 1996. It is shown in Figure 6. Clouds have a hundred times stronger effect on weather and climate than carbon dioxide in the atmosphere."

Has this paper been directly rebutted on SkS?

I preume that Dana's "What's the net feedback from clouds" post is an indirect rebuttal.

Yes Svensmark is the galactic cosmic rays impacting global temperatures through cloud seeding argument.  I discussed that one in the link Glenn provides.

However, I have no idea where your nemesis get the "hundred times stronger effect" bullshit.  Even Svensmark wouldn't say anything so absurd.  Svensmark thinks GCRs have a larger effect than they do in reality (which is very little), but I doubt he would argue that they have any more effect than CO2, let alone 100 times more.  Your nemesis is talking out his butt.

Here's my take on S & F-C (1997):

And a few papers on the minor effect of cosmic rays to climate:
