JAMAIS CASCIO: The Need for Geoengineering - [More pure climate insanity on] WSJ.com

If we’re going to avoid climate disaster, we’re going to have start getting a lot more direct. We’re going to have to think about cooling the planet.

The concept is called geoengineering, and in the past few years, it has gone from being dismissed as a fringe idea to the subject of intense debates in the halls of power. Many of us who have been watching this subject closely have gone from being skeptics to advocates. Very reluctant advocates, to be sure, but advocates nonetheless.

What has changed? Quite simply, as the effects of global warming have worsened, policy makers have failed to meet the challenge. As a result, if we want to avoid an unprecedented global catastrophe, we may have no other choice but to reduce the impact of global warning, alongside focusing on the factors that are causing it in the first place. That is, while we continue to work aggressively to reduce the amount of carbon released into the atmosphere, we also need to consider lowering the temperature of the Earth itself.
