CERN Studies Connection Between Cosmic Rays and Climate Change

Layzej writes with this quote from Nature: "For a century, scientists have known that charged particles from space constantly bombard Earth. Known as cosmic rays, the particles are mostly protons blasted out of supernovae. As the protons crash through the planet's atmosphere, they can ionize volatile compounds, causing them to condense into airborne droplets, or aerosols. It is hypothesized that clouds might then build up around the droplets — possibly affecting the Earth's climate. To find out, [Jasper] Kirkby and his team are bringing the atmosphere down to Earth in an experiment called Cosmics Leaving Outdoor Droplets (CLOUD). ... Early results seem to indicate that cosmic rays do cause a change (abstract). The high-energy protons seemed to enhance the production of nanometer-sized particles from the gaseous atmosphere by more than a factor of ten. But, Kirkby adds, those particles are far too small to serve as seeds for clouds."

    I like how, when faced with decades of research on the CO2 - global warming connection, the anti-AWG crowd are completely skeptical. But, a hint that cosmic rays might affect cloud formation and climate change, and they're already convinced.

    It fits pretty nicely with other research that showed that people's willingness to accept global warming seemed to hinge on whether or not they needed to change their lives as a result. (As if facts were true or not depending on their consequences for their own lives.)

    In one version of the news story, however, the scientific study was described as calling for “increased antipollution regulation,” whereas in another it was described as calling for “revitalization of the nation’s nuclear power industry".... individualists who received the “nuclear power” [solution to global warming] were less inclined to dismiss the facts [of global warming] related by the described report http://thesituationist.wordpress.com/2007/10/02/nuclear-power-makes-individualists-see-green/

    I'm honestly not sure how you can come to this conclusion. Look at the graph:

    I was convinced there was more to this after reading Calder's book, "The Chilling Stars", quite some time ago. This experiment simply adds to the evidence gathered and presented there. The next question concerns the growth of CCN after this initial formation of small sized particles. It's interesting to me that this is immediately dismissed by hockey-stick fiddlers. There is a certain closed-mindedness to anything other than the current dogma in certain circles.
