The world is warming, you report, and a “new analysis” of the temperature record leaves little room for doubters (“The Heat is On,” October 22, 2011). The doubters are not likely to vanish because of the new analysis, though. Across much of the world, they can already feel the heat all by themselves. This time around, science has failed us pretty badly. The squabble that spoiled the Copenhagen meeting on climate change in 2009 will not be easily forgotten, either. If there are doubters nowadays, they focus on science rather than global warming. All the fine things you have to report on new scientific efforts to ascertain exactly by how much the temperature record has changed is becoming irrelevant to most. People are turning to their own lives and trying to figure out what to do as warming continues. Some will have to move. Others will have to fortify their abodes. And almost all will have to figure out how to do whatever they do under the changing circumstances. But few of them will look to science for advice, for they have had enough of scientific squabbles. Thanks to Copenhagen, of course.
