Wild and Crazy Ideas to Cool the Planet


Last year we sort of made fun of Mike's (pre-treehugger) idea for an artificial partial solar eclipse- a giant reflective orbiting space blanket to reduce amount of sun reaching the earth by a few percent to counteract global warming. Perhaps he should have patented it- The New York Times recently listed a plethora of zany suggestions- pumping reflective sulphur dioxide into the atmosphere; floating giant white foam frisbees to reflect sunlight; even orbiting Mike's giant reflector. It is all about geoengineering, or "rearranging the earth's environment on a large scale to suit human needs". It seems to us that we have done a bit too much geoengineering already. ::New York Times see ::worldchanging on the same subject and ::Mike's post here
