Aarhus beats Geneva
Climate Change News and Comments
While the world waits for the report due soon from the CLOUD experiment at CERN in Geneva, as noted in my previous post, a team working in Denmark has published the results of a cheaper and quicker experiment done last year with a particle accelerator at the University of Aarhus. They fully confirm the support for the Svensmark hypothesis (that cosmic rays help to make clouds) which came from earlier Danish experiments using natural cosmic rays and radioactive sources of ionizing gamma rays.
The paper, published on 12 May 2011, is by M.B. Enghoff, J. O. Pepke Pedersen, U. I. Uggerhøj, S. M. Paling, and H. Svensmark, “Aerosol nucleation induced by a high energy particle beam,” Geophysical Research Letters, 38, L09805, doi:10.1029/2011GL047036.
The abstract is available here: http://www.agu.org/pubs/crossref/2011/2011GL047036.shtml
Press releases from the Technical University of Denmark (DTU) and the University of Aarhus are expected very soon and will be added here when available in English.
