Global-warming proponents betray science by shutting down debate

and

Climate-change science is “settled,” say proponents of anthropogenic (human-induced) global warming, or AGW: the earth is getting warmer, and human activities are the reason. The Intergovernmental Panel on Climate Change (IPCC), set up by the United Nations in 1988, has issued five assessment reports since its founding. In its most recent, in 2013, the IPCC stated that it was now “95 to 100 percent certain” that human activities—especially fossil-fuel emissions—are the primary drivers of planetary warming. Frequent news reports—such as the story of the melting of the West Antarctic Ice Sheet, a process that some scientists say is irreversible—seemingly confirm these conclusions.

And yet, highly credentialed scientists, including Nobel Prize–winning physicist Ivar Giaever, reject what is often called the “climate consensus.”
and 

Genuine scientific inquiry is degraded when science becomes politicized. The standards that have prevailed since the Scientific Revolution conflict with the advocacy needs of politics, and AGW would be finished as the basis of a political program if confidence in its scientific consensus were undermined. Its advocates’ evasion of rigorous falsifiability tests points to AGW’s current weakness as a science.
