Ah, but, but, uh, cosmic rays are cause by global warming! Yeah, that's it!! And cosmic rays cause clouds, and clouds cause cooling so, see, we were right!! Global warming is causing global cooling! Nyah, nyah, nyah, nyah, nyah!
That is probably going to be their response too
Cosmic Rays —> Clouds —> Cooling
Sunspots —> Less Cosmic Rays —> Less Clouds —> Warming
Of course, no grants, Oscars or Nobels for this analysis.
