Geoengineering the Climate

Mark Whitaker reports from Britain and the USA on the science of geoengineering and the political questions it raises. Putting giant parasols in space, injecting substances into the stratosphere, fertilising the oceans and brightening the clouds are all techniques to cool the earth, by reducing sunlight or removing carbon dioxide from the atmosphere. Until recently they were the stuff of science fiction but now they are being taken seriously on both sides of the Atlantic.

A Square Dog production for BBC Radio 4.
