CNB,
Although not in a conventional positioning, let me offer a further thought on one of your comments.
You say, “There is no serious scientific debate over…the historical temperature record…We would do a serious dis-service to students to do otherwise.” (yr Jan 20, 1:40 pm)
CNB, you’re a teacher–a science teacher–I gather from your comments on this thread. And, as a teacher, I think we’d both agree, you have a duty, if an ethical person (of the old-fashioned bourgeois morality stripe, that is), to teach children in your care science within the context of critical thinking. And, in that regard, ethical science instruction cannot properly take the form of indoctrination of the kids, at the point of a knowledge-spike in the back of the head, with science factoids and pseudo-factoids selected to advance the latest lefty, brave-new-world hustle (incidentally, in my youth, it was the “conservatives” who were doing the indoctrinating–no more palatable than the left, I might add). Again, I’m sure we agree, right CNB?
Now, you’ve declared rather boldly, CNB, that there is no “serious scientific controversy” with regard to the historical temperature record (see above quote). Subsequently, Roger Caiazza immediately challenged your contention that the historical temperature record known and that knowledge is blessedly free of any serious scientific controversy (his January 20, 1:57 pm). To my disappointment you did not respond to Roger.
Please allow me pose Roger’s challenge myself. But let me do so in the guise of student in your class:
“Mr./Ms. CNB, I don’t get it! How can people know what the temperature was in the whole world tens and hundreds and millions of years ago to tenths of a degree? I mean, for some of that time, there weren’t even thermometers. And even today, there aren’t measuring devices in much of the world. Indeed, there weren’t even people around a while ago to take the temperature. So again, Mr./Ms. CNB, how can we be sure of the historical global temperature record, to within TENTHS OF A DEGREE AND WITH NO SERIOUS SCIENTIFIC CONTROVERSY IN THE MATTER? ”
So what’s your answer to this imaginary student of yours, as a science teacher, CNB?
