Modelling of the climatic system and its response to human activities
Only mathematical models are able to predict the climate change that will be induced over the next decades by the increase of the atmospheric concentration in greenhouse gases. To produce such forecasts it is necessary to work out a model of the Earth's climate system encompassing, at least, th...
