On Monday, I noted in Mother Jones that a failure in Copenhagen would strengthen the would-be geoengineers, some of whom–like the Russians–are already starting to fire sulfates into the air in field trial experiments.
Well, there has been a failure–or at least, a very weak agreement–in Copenhagen. Expect to hear more and more talk about geoengineering as this ongoing climate policy mess–now two decades old–continues and continues and continues.
I am not in favor of geoengineering, but I am in favor of geoengineering research–and pragmatic solutions. And if the policy process can’t deliver a global cutback in emissions sufficient to avert “dangerous anthropogenic” climate change, then I think geoengineering has to be in our toolkit as a last option.
Unfortunately.

I was lucky, and I want to encourage readers in the northeast to keep black ice in mind as you brave the roads this morning. And since this is Discover blogs, what causes the slippery stuff anyway?








Keith's note: It would seem that Science Magazine jumped the gun a bit. As is the case with the Orlando Sentinel, NASA Watch sources report that the
