Climate Change: Should We Speak of Consensus?

In a recent lecture, Naomi Oreskes, a distinguished historian of science from the ‎University of California, San Diego, has argued that there is and has been a scientific ‎consensus that human-caused global warming is occurring. She persuasively shows that the ‎sceptical claims about human-caused global warming have not originated from within ‎the scientific community, but rather from politically motivated external ‎actors who, consciously and one would even say cynically, have been artificially ‎manufacturing controversy on the subject.‎

What are we, however, to make of this claim? On its own, the existence of a scientific ‎consensus does not indicate that the consensus view is correct. Oreskes does have a ‎point about the consensus being initially shared by people of different political views. But ‎it seems that for her – in this lecture at least – politics affect only one side of the debate. ‎Doesn’t it need to be shown that, at least once the climate debate became politicized, ‎similar political influences have not affected the other side as well?‎
