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.

Calder's Updates 
How big is AGW’s coffin? There are so many nails in it they must be defying the Pauli exclusion principle. The Danes have knocked in another.
Vikings have a way of drawing blood first regardless of the obstacles. Must be those temperate climes and all that sunshine that only comes out on feast days.
So short an abstract- so profound an implication.
[…] Accelerator results on cloud nucleation […]
This is very welcome news, and needs to be shouted from the rooftops, and most certainly through the front doors of DECC.
I agree, another nail in the AGW coffin, but I suspect there’s a long way to go yet, with more downhill before the climb back up.
[…] [8] Accelerator results on cloud nucleation […]
It is shameful and unacceptable when a leading scientist at CERN forbids any evaluation of the results of the CLOUD experiment even before any data are published. This man is obviosly unable to perform his scientific duties and should be removed from CERN.
[…] och ”deniers”. Men frågan är vad de båda experimenten under sommaren, experimentet i Aarhus och senare i CERN, har haft för betydelse för teorins ställning inom klimatforskningen. […]
