I am delighted to be spearheading a forthcoming workshop to be held at Reading University in July that brings together observationalists and modellers working on palaeoclimates, model development and assessment of future climate changes to address this question.

Climate models are mathematical representations of the interactions between the atmosphere, oceans, land surface, ice – and the sun. The models used for future climate projections were developed and calibrated using climate observations from the past 40 years. They are also the only tools available to project the human impact on the environment changes over the 21st century. These models perform well in terms of global features (e.g. magnitude of global warming), but model performance at a regional scale is poor.
