Unlike electromagnetic radiation, which consists of massless and accelerated charged particles, galactic cosmic rays (CR) are composed mostly of atomic nuclei and solitary electrons, objects that have mass. Cosmic rays originate via a wide range of processes and sources including supernovae, galactic nuclei, and gamma ray bursts. Researchers have speculated for decades on the possible effects of galactic cosmic rays on the immediate environs of Earth's atmosphere, but until recently, a causal relationship between climate and cosmic rays has been difficult to establish.
A research collaborative has published a paper in the Proceedings of the National Academy of Sciences that mathematically establishes such a causal link between CR and year-to-year changes in global temperature, but has found no causal relationship between the CR and the warming trend of the 20th century.

So what happens, if "Global warming" is actually being caused by an increase in Cosmic Rays? We're assuming that the poor handling and small sample size of Temperature data are accurate. We all just get to cook together in a giant Cosmic Stew? Mmm..., would you like fries with that? Or will we realize there's no actual threat, because the Earth can handle a bit of fluctuation?

Oh, the Earth can handle the fluctuation no trouble, it's a planet after all - it's just us that are screwed when the tarnish-thin smear of biological crap on the surface dies off.
