Predicting how the climate will change as human activities lead to emission of more greenhouse gases is a global scientific challenge for climate scientists. We use models of the climate to make predictions, but predictions from these models are imperfect. We are therefore faced by the huge challenge of extracting robust information from climate models about how real-world climate will change in the future under specified scenarios of different greenhouse gas emissions. Scientists at BAS are focussing on understanding the processes driving sea ice variability and change, and combining this information with novel analysis methods to investigate the likely future evolution of Antarctic sea ice area.
