"In 1979, physicist Freeman Dyson, in his characteristically prescient manner, proposed the deliberate, large-scale introduction of such fine particles into the upper atmosphere to offset global warming, which he thought even then would eventually become a human concern. Some of my colleagues and I have recently surveyed the current technological prospects for such an introduction. We estimated the costs involved and presented our results last August at the Twenty-second International Seminar on Planetary Emergencies. The most expensive such "geoengineering" option appears to be the one long ago proposed by Mr. Dyson, which may cost as much as $1 billion a year. More technologically advanced options along the same lines might cost $100 million."
