Michael Spencer examines geo-engineering:
[Hugh] Hunt [of the Stratospheric Particle Injection for Climate Engineering project] stood up, walked slowly to the window, and gazed at the manicured Trinity College green. "I know this is all unpleasant," he said. "Nobody wants it, but nobody wants to put high doses of poisonous chemicals into their body, either. That is what chemotherapy is, though, and for people suffering from cancer those poisons are often their only hope. Every day, tens of thousands of people take them willingly—because they are very sick or dying. This is how I prefer to look at the possibility of engineering the climate. It isn’t a cure for anything. But it could very well turn out to be the least bad option we are going to have.’"
