He's better described as a self serving political populist with this being one of several interesting chapters:

  After the publication of The Skeptical Environmentalist, Lomborg was formally accused of scientific dishonesty by a group of environmental scientists, who brought a total of three complaints against him to the Danish Committees on Scientific Dishonesty (DCSD), a body under Denmark's Ministry of Science, Technology and Innovation (MSTI).

  In January 2003, the DCSD released a ruling that sent a mixed message, finding the book to be scientifically dishonest through misrepresentation of scientific facts, but Lomborg himself not guilty due to his lack of expertise in the fields in question.

ie. He skated on a dishonesty charge as he was deemed to be to inept to know just how badly he was misrepresenting data.

To be honest I thought he'd faded away, but it's interesting to see his shit still being dragged up to rot in the sun again.

The finding was annulled.

He actually thinks global warming is happening and man made. He just demonstrates that the cure in some cases is worse than the disease.
