Geoengineering is the study and implementation of planetary engineering techniques to modulate the Earth Climate. Many scientists now support serious research into geoengineering, deliberate actions taken to slow or reverse global warming. Of the various geoengineering proposals, the ones that shade the earth from the sun could bring about the most immediate effects. But all of them have drawbacks and side effects that probably cannot be anticipated. Pumping sulfur dioxide into the stratosphere, as volcanoes do, is the most well established way to block the sun. Other proposals call for brightening clouds over the oceans by lofting sea salt into the atmosphere and building a sunscreen in space. In this overview lecture I will introduce the concept of geoengineering and provide some examples of the most promising approaches.
