The models which are used to estimate equilibrium and evolving changes in climate, due to increases in greenhouse gas concentrations, are described. Results from a 75‐year experiment with carbon dioxide increasing at 1%/annum using a coupled model of the atmosphere, land and deep ocean, are presented and compared with those from equilibrium experiments. Rainfall over the UK increases over the year as a whole, with the largest changes in winter; however, in summer it decreases except in the north. Soil moisture decreases except in winter. Results from an equilibrium experiment show that rainfall tends to be more intense but less frequent with a doubled atomospheric concentration of CO 2 . A scenario of climate change over western Europe is included, based on these and other experiments.
