The Intergovernmental Panel on Climate Change (IPCC) has been established by WMO
and UNEP to assess scientific, technical and socio-economic information, relevant
for the understanding of climate change,
This simulation was performed with the first version of the coupled global model CGCMI with the standard concentration of CO2. Details of the model and an analysis of the simulation are given in Flato
This simulation was performed with the first version of the coupled global model CGCMI. The model is forced by an effective greenhouse forcing corresponding to that observed from 1850 to the present,

The control integration, in which the atmospheric forcing is kept constant, simulates a period over 240 years (1860-2099) in length. Control experiment (CTL): The control integration, in which the atmospheric
Here the greenhouse gas forcing is increased gradually to represent the observed changes in forcing due to all the greenhouse gases from 1881 to 1990. From 1990 to 2100 it uses an increase in concentrations
The forcing includes not only the greenhouse gas forcing described with the "greenhouse run" but also the direct radiative effect of sulphate aerosol concentrations. The direct aerosol effect was included
