Abstract
A two-dimensional climate model (LLN-2D) has been used to investigate long-term climate change (over periods of around 105 years in the past and in the future) for Central England. The model is forced by periodic changes in the distribution of incoming radiation associated with periodic changes in the Earth’s orbit around the Sun and by changes in the atmospheric concentration of CO2. Future natural changes in CO2 concentration are estimated using a regression equation. Eight anthropogenic CO2 scenarios have been constructed. The LLN-2D simulations indicate that anthropogenic effects have the potential to disturb the climate system over very long time scales and demonstrate the non-linearities that can operate between cause and effect.KeywordsGlacial PeriodAtmospheric ConcentrationGlacial EventBoreal ConditionHigh Resolution Regional Climate ModelThese keywords were added by machine and not by the authors.
