Haigh Status of first author: ---------------------------------------- Title: Solar Influences on Global Climate Change and the IPCC Report ---------------------------------------- Authors: Dr Joanna D. Haigh Imperial College of Science, Technology and Medicine, London, UK j.haigh@ic.ac.uk ---------------------------------------- Abstract: The structure and workings of the Intergovernmental Panel on Climate Change (IPCC) will be described, including how its Third Assessment Report (TAR, published 2001) was written and reviewed. The conclusions of the TAR concerning to what extent solar variability influences climate will be discussed. The concept of the radiative forcing of climate will be depicted and problems and uncertainties associated with the calculation of solar radiative forcing outlined. The results of some more recent studies of the effects of solar variability on climate using general circulation models of the atmosphere will be presented. ---------------------------------------- Long-Term Relations in Sun-Earth Climate (part of S-RAMP/SCOSTEP)
