Abstract
In this study, it was found out that ion chamber measurements of cosmic ray fluxes during the last solar cycle ending in 2009 differ essentially from neutron measurements. The ion chamber measurements utilizing geomagnetic aa index as proxy for the years between 1868 and 1936 produced excellent correlation to the global temperature changes for the period of 1868 to 2009. These results indicate that solar activity changes may cause climate changes.
Key words: Cosmic rays, ion chamber measurements, climate change, solar cycle.
