Bill McKibben, founder of 350.org, spoke on Sunday at the “Forward on Climate Rally” in Washington, D.C. He said, “Science should have decided our course long ago.” He was right. If only environmental policy were based on what science really says, billions of dollars would not have been wasted trying to “contain climate change,” as 350.org nonsensically demanded of President Obama this past weekend.
No matter what Mr. McKibben and Al Gore tell us, experts in the field understand that climate science is highly immature. We are in a period of “negative discovery,” in that the more we learn about climate, the more we realize we do not know. This problem is compounded by the fact that much of the data used by campaigners to try to convince the public that we are in an unusual period climatically is either wrong or highly suspect.
Rather than “remove the doubt,” as Mr. Gore tells us should be done, we must recognize the doubt in this, arguably the most complex science ever tackled.
The confidence expressed by Mr. Gore, Mr. McKibben and Mr. Obama that mankind is causing dangerous climate change is a consequence of a belief in what professors Chris Essex (University of Western Ontario) and Ross McKitrick (University of Guelph) call the “Doctrine of Certainty.” This doctrine is “a collection of now familiar assertions about climate that are to be accepted without question” (“Taken by Storm,” 2007).
Mr. Essex and Mr. McKitrick explain, “But the Doctrine is not true. Each assertion is either manifestly false or the claim to know is false. Climate is one of the most challenging open problems in modern science. Some knowledgeable scientists believe that the climate problem can never be solved.”
