3. GCM PROJECTIONS AND GLOBAL TRENDS IN RAINFALL
In recent years, an impressive pile of reports has been published on changes in
the climate as predicted by GCMs. An effort has been made here to extract the
most recent information. After describing some of their characteristics, the review
starts with the findings of transient global climate simulations and relevant
results of mixed-layer models. (Results of regional-scale modelling will be
summarised separately.) To compare, information on trends in rainfall on the
global scale is given.
