Thoughtful piece in the Economist. It starts from the revelation by a new Pew Research poll which finds that 53% of Republicans say there is no solid evidence the earth is warming. Among Tea Party Republicans, 70% say there is no evidence. Pew goes on to point out that “Disbelief in global warming in the GOP is a recent occurrence. Just a few years ago, in 2007, a 62%-majority of Republicans said there is solid evidence of global warming, while less than a third (31%) said there is no solid evidence. Currently, just 38% of Republicans say there is solid evidence the earth is warming, and only 16% say that warming is caused by human activity.” The article goes on:
It’s one thing to hold the position that rising global temperatures are due to natural variation, not human activity. I consider that position wrong and dangerous, but it’s a dispute over the analysis. But it is simply a fact that the planet is getting warmer. That many people who previously knew this have come to un-know it indicates that people are busy at work promoting ignorance.
Reminds me of Daniel Moynihan’s wonderful principle: everyone is entitled to his own views, but not to his own facts.
