The main topics of my research are: Solar and heliospheric physics, in particular solar magnetism Sun-Earth relations and physics of the solar atmosphere A misleading account of my views was published in the Toronto National Post in March, 2007 (and is to be found at different places on the web). In contrast to what is written there I am not a denier of global warming produced by an increase in the concentration of greenhouse gases. Already at present the overwhelming source of global warming is due to manmade greenhouse gases and their influence will continue to grow in the future as their concentration increases.
