[I think that as a climate-saving strategy geoengineering is largely somewhere between a dead end and a hoax -- why would you choose chemotherapy that might make you sicker if your doctors told you diet and exercise would definitely work (see "Geoengineering remains a bad idea")? In retrospect, that analogy isn't perfect. The "diet and exercise" the country and the world needs is more like what the winner of the reality show "The Biggest Loser" undergoes. And the chemotherapy is actually more like an experimental trial for a combination of chemotherapy and radiation therapy, where you have no idea at all if the treatment will work, as opposed to kill you outright, and you might be on the placebo. I have been planning to do a longer series on geoengineering, and Bill Becker's post seemed like a good place to start.]
I do not plan to make a career out of beating up on geo-engineers, but they were back in the news recently in articles published by the on-line magazine Yale Environment 360 and by The Economist.
For those of us who believe that engineering the Earth’s life-support systems is a wild and dangerous fantasy, there was good news and bad news.
The “good news” was reported by The Economist: Two new studies conclude that geo-engineering is not as promising an answer to climate change as some in that budding discipline hope.
If you are not yet familiar with geo-engineering, I will attempt to define it in non-technical terms before offering a few observations on the new research:
