In this presentationProf Sir Brian Hoskins, Director of the Grantham Institute Imperial College, gives a summary of the essentials of climate science, noting the scale of man-made additions to the CO2 stock in the atmosphere, the inevitable uncertainty in specific projections, and implications for future global climate. By continuing to emit greenhouse gases to the atmosphere we were performing a very dangerous experiment with planet Earth. Possible policy responses grouped included mitigation, geo-engineering, and adaptation. On geo-engineering, the main drawbacks were potential cost, global governance, and potential irreversibility of commitment to geo-engineering solutions.
