Galactic cosmic rays and our world.

  1. Dec 22, 2008 #1
    Recently on nasa's site:

    http://science.nasa.gov/headlines/y2008/19nov_cosmicrays.htm


    My question is...has there been any studies since 2004 to show the link between galactic cosmic rays, and cloud formation, and/or changes in cloud forming bacteria and/or the effect these have on the marine life especially red tide algae?

    Can you point me in any direction?

    I don't think the ATIC results have anything to do with cloud formation, and/or changes in cloud forming bacteria and/or the effect these have on the marine life especially red tide algae.

    It appears more to do with water temperature, water chemistry and nutrients rather than cosmic rays.

    I believe that recent theories claiming a strong link between clouds and cosmic radiation have been shown to be incorrect. Perhaps there is a weak link or none at all.

    I probably put this in the wrong place. :wink: Feel free to move it.

    In the article below...it shows that galactic cosmic rays affected our planet before...or this is the theory. It affected the bacteria and algae in the oceans millions of years ago. What im wondering is if these high energy electrons from a nearby source wouldnt have the same effect as on oceans like it had then.
