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.

    Photons have alternating charge. That's why they exhibit the particle/wave duality.

    Gamma rays are not radiation. Like the summary says, they are made of protons, neutrons and electrons. Maybe you're thinking of alpha and beta radiation?

    This is pretty basic physics. How are you misunderstanding so much of it?

    What age group do they start teaching that level of physics to? Should give you a clue as to why the ignorance...

      I learned that type of physics during my first semester of college. Maybe FatPhil never went to college?

    Photons don't have alternating charge. Instead they have no charge.

    Ignoring the *not even wrong* "alternating charge" comment...

    > Gamma rays are not radiation.

    Snigger. Is stupidity like yours painful?

      Just because you disagree with the GP it does not mean that you need to use racial slurs.

        I'd mod you funny if I were logged in. We shouldn't be so niggardly with our vocabulary education.

    Umm, no, you've got your radiation all mixed up.

    Gamma rays are extremely high-frequency electromagnetic radiation - some single photons have been detected with a mass-energy comparable to an entire iron atom!
    Cosmic Rays are extremely high-speed charged particles of various types (mostly atomic nuclei) originating from outside the solar system
    Alpha radiation is high-speed Helium-2 nuclei
    Beta radiation is high-speed electrons and positrons
    Neutron radiation is high-speed neutrons

      Oops, I lied - alpha radiation is Helium-4, not 2. somehow "helium with 2 neutrons" got turned around when I as typing.
