Ann Althouse posted the conclusion to this piece stating that Lomborg, the environmental skeptic on global warming. TNR thinks that he has turned on his former skepticism because of statements like this:
The world’s most high-profile climate change sceptic is to declare that global warming is “undoubtedly one of the chief concerns facing the world today” and “a challenge humanity must confront”, in an apparent U-turn that will give a huge boost to the embattled environmental lobby.
TNR also thinks he may be opportunistic because he is calling for money to be spent:
“Investing $100bn annually would mean that we could essentially resolve the climate change problem by the end of this century,”
TNR makes way too much of this if you follow closely the quotes provided. First, Lomborg states that climate change is a “chief concern” that “humanity must confront.” He never says climate change is true. He says the idea of climate change must be confronted, and more specifically, the challenge must be confronted. This does not mean he agrees with those who are making the claim climate change is a scientific truth. Second, he resolves money should be spent to resolve the problem of climate change. Again, this does not mean Lomborg thinks global warming is a truth. It suggests that further study needs to be conducted.
In other words, Lomborg is calling for money to be spent on further study, via the scientific method.
