Reseach:

Experimental achievements

In 1996 discovered a possible link between solar activity and Earths climate through the influence of cosmic ray ionisation on Earth’s cloud cover. This result received large interest from both scientist and media. It gave rise to large controversy mainly due to the political interest in manmade Global warming, which received the above idea as a competing theory.
In 1997-1998 the first initiative was taken to test a potential microphysical mechanism, linking cosmic rays and clouds experimentally.
In 2001, took initiative to build and perform an experiment in Copenhagen. The next three years work went into, making a new laboratory at DNSC, designing the experimental set-up, building the apparatus, and most importantly finding funds to finance the experiment.
In 2004 efforts was used at testing and calibration of the experimental set-up.
In 2005 real experiments began. The experimental set-up, and performance of the reaction chamber is unique and is the only one in the world. It has unique ion-control features and trace-gas control which permits for the first time to do experiments at ion-densities and trace-gas concentrations relevant for the Earth’s atmosphere.
In 2006

Theoretical achievements

Consequences of a cosmic ray link to climate have been traced to climate variations covering millions to billions of years. My latest work suggest that the cosmic ray climate link has had influence over whole 4.6 billion year history of the Earth, which in turn have had impact on the biological evolution. The results suggest that the evolution of the Milky Way and the Earth is closely linked.
