The front page of yesterday’s New York Times included the beginning of a long article about geoengineering—in this case, as it applies to purposeful activities aimed at changing the earth’s climate at a large scale. Why on earth would anyone even think of doing something like that? Why to avoid catastrophic global warming, of course!
Thankfully, most signs point to only a modest global temperature increase resulting from our fossil fuel usage—a rise that will be readily adapted to and which actually may work out to be more beneficial than detrimental. Thankfully, we say, because geoengineering schemes seem like really bad ideas full of nasty consequences (unintentional and otherwise) and we are glad that no one is seriously entertaining them.
Most folks who spend much time critically thinking about geoengineering the climate arrive at the same conclusion.
