Computer modelling, or simulation, is one of the most controversial aspects of the global warming and climate change debate. Models are used to estimate the effect of CO2 on the atmosphere, and the first and further-order effects of global warming. Some scientists even believe that modelling can predict how things like crime and conflict will be influenced by a warmer atmosphere, leading to the breakdown of society. Articles in this category consider all claims of this kind, and the role of modelling in the scientific and political understanding of global warming and climate change.
