Geo-engineering is the deliberate modification of large scale geophysical processes … The first of the two most common examples cited is placement of reflective aerosols into the upper atmosphere in order to reflect incoming sunlight and thus reduce global temperature.\ \ \ \ \ The eruption of Mount Pinatubo in the Philippines in 1991 injected a significant amount of sulfur dioxide into the stratosphere, lowering the Earth’s surface temperature by about (half a degree) the year following the eruption.\ \ \ … Because these techniques mimic natural phenomena, we know more about how quickly and well they work than we do about the efficacy of attempting to reduce greenhouse gases. We have measured the effects of the natural processes and can state with considerable certainty, bordering of complete certainty, that they will produce the result sought. Although the effects of greenhouse gas reduction would occur over a period of no less than decades and more likely centuries, the effects of geo-engineering can (and will) be manifest in a matter of weeks after application.

… Geo-engineering is … 200 to 2,000 times less expensive … than exclusive reliance on carbon control.
