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. The same newspaper already misquoted other
scientists on this topic. See, for example, the home page of Nigel Weiss of
Cambridge University
