There are indications that increases in extremes of such variables as temperature and precipitation are likely. However, because climate models still cannot resolve all processes that are responsible for extreme events, all the results reported above should be interpreted cautiously. 7 The IPCC Third Assessment Report New scenarios of future emissions of the various greenhouse gases and aerosols are currently being developed by Working Group III for the IPCC Third Assessment Report to be completed in 2001.

Knutson and Manabe (1994), analysing the Geophysical Fluid Dynamics Laboratory (GFDL) AOGCM, found decreased amplitude in the Southern Oscillation Index (SOI) in a transient 4 × [CO2] experiment. They emphasized that their results were from a coupled model, the ocean component of which had a rather coarse resolution. Thus, this model may not realistically simulate coupled Climatic Change and Variability 27 ocean/atmosphere responses in the tropical Pacific Ocean. Knutson et al. (1997) also found decreased amplitude of ENSO, but found no change in the frequency of El Niño/La Niña events with increasing concentrations of atmospheric CO2.
