According to Matt Nisbet, the third ethical imperative when framing science is accuracy. Accuracy is important, he argues, because those who fail to accurately convey what's known about a subject risk losing the trust of their audience.
Also according to Matt Nisbet, a new Pew survey shows that Evangelicals are "little different from [the] rest of [the] public" when it comes to acceptance of manmade climate change. Evangelicals are 13% less likely to accept that humans are causing global warming as the population as a whole, no other group is less likely to accept manmade warming than they are, and the next lowest group is 5% more likely to accept what's happening than Evangelicals are. Evangelicals are also 10% more likely to believe that there's no warming taking place than the rest of the public, 9% more likely to believe that there's no warming than the next highest group, and there's no group where a larger percentage reject warming. Apparently, the phrase "little different" has a much broader meaning than I thought it did when it's used "accurately".
