In
context of the results of the World Climate Change Conference which
took place in Moscow during the time period September 29 – October
3 (WCCC 2003) an analysis has been made of key issues of contemporary
global climate change. The principal attention has been paid to
the discussion of uncertainties of existing observation data and
numerical modelling results. As fas as numerical modelling is concerned,
a necessity has been emphasized of an analysis of present day models
from the viewpoint of their ability to simulate real climate change
which results from nonlinear interactions between numerous climatic
system’s components taking also into account potential contributions
of cosmic factors such as solar activity.
