“BREAKING NEWS – CERN Experiment Confirms Cosmic Rays Influence Cloud Seeds” (2011-08-24). Anthony Watts tells the world that a cosmic ray experiment at CERN (“CLOUD“) proves that global warming is all because of cosmic rays! Thus ending global warming once and for all. The AGW theory is “dented”!
Anthony’s analysis consists pasting in a biased interpretation by the Global Warming Policy Foundation’s elderly denialist, and Henrik Svensmark pal, Nigel Calder. Henrik Svensmark is the widely discounted proponent of galactic cosmic rays as the source of all climate change.
Hmmm… Could it be true that “CERN Experiment Confirms Cosmic Rays Influence Climate Change”?
Well, maybe cosmic rays contribute to ionization, but the experiment being hailed by denialists only detected events at scales too small to trigger droplet formation. Sadly, historical climate change patterns also show no correlation at all with cosmic rays. So… maybe not.
