I am quite confident that most readers of this blog would agree that NASA's James Hansen is a pretty big hero. Nevertheless, he shouldn't be saying stuff like this:
Recently, after giving a high school commencement talk in my hometown, Denison, Iowa, I drove from Denison to Dunlap, where my parents are buried. For most of 20 miles there were trains parked, engine to caboose, half of the cars being filled with coal. If we cannot stop the building of more coal-fired power plants, those coal trains will be death trains - no less gruesome than if they were boxcars headed to crematoria, loaded with uncountable irreplaceable species.
A related alternative metaphor, perhaps less objectionable while still making the most basic point, comes to mind in connection with an image of crashing of massive ice sheets fronts into the sea -- an image of relevance to both climate tipping points and consequences (sea level rise). Can these crashing glaciers serve as a Krystal Nacht, and wake us up to the inhumane consequences of averting our eyes?
In my latest DeSmogBlog item, I explain why it's just dumb and counterproductive (not to mention offensive) to use Holocaust analogies in a global warming context. Full analysis here. Upshot: James Hansen is a hero all right, but that certainly doesn't make him perfect.
