At conservative David Frum’s NewMajority.com website, John Murdock does his best to explain why Drudge headlines and Al Gore hatred should not be the engine that drives Republican “thinking” on global warming:
For hundreds of thousands of years, CO2 has ranged between about 180 and 300 parts per million (ppm). Currently we are at 385 ppm . . . and with each SUV trip to [the] grocery store and new Chinese coal power plant we all contribute, in big and small ways, to a rapid rate of increase. . . . Frankly, no one knows what the future holds at 500 or 600 ppm, but we can surmise that it probably will not be good.
Where Murdock cites data he derives it from an atmospheric physicist who is also an Evangelical Christian. In other words, he even tries to overcome the ethos (source credibility) problem that usually serves to shut down his audience on this topic.
Good luck to him—and the rest of us.
