Our climate is determined by the interactions between internal mechanisms (plate tectonics) and the receipt and processing of solar radiation. For most of geologic time that has conditioned a world much warmer than the current one with a larger greenhouse effect. Contemporary global warming reflects our inadvertent interference with the natural balance, mostly through the burning of fossil fuels. So far mean global temperature has increased by only 1.5°C over the last 70 years, but climate models predict that the world will warm by as much as 4°C by 2100.
                    What impact will that have? 
                     Can we stop it happening?
                   Can we redress the situation?
