http://en.wikipedia.org/wiki/Bjorn_LomborgThe Skeptical Environmentalist
In 1998, Lomborg published four articles about the state of the environment in the leading Danish newspaper Politiken, which according to him "resulted in a firestorm debate spanning over 400 articles in major metropolitan newspapers."
In 2001, he attained significant attention by publishing The Skeptical Environmentalist, a controversial book whose main thesis is that many of the most-publicized claims and predictions on environmental issues are wrong.
Accusations of scientific dishonesty
After the publication of The Skeptical Environmentalist, Lomborg was accused of scientific dishonesty. Several environmental scientists brought a total of three complaints against Lomborg to the Danish Committees on Scientific Dishonesty (DCSD), a body under Denmark's Ministry of Science, Technology and Innovation. The charges claimed that The Skeptical Environmentalist contained deliberately misleading data and flawed conclusions. Due to the similarity of the complaints, the DCSD decided to proceed on the three cases under one investigation.
DCSD investigation
On January 6, 2003 the DCSD reached a decision on the complaints. The ruling was a mixed message, deciding the book to be scientifically dishonest, but Lomborg himself not guilty because of lack of expertise in the fields in question:
Objectively speaking, the publication of the work under consideration is deemed to fall within the concept of scientific dishonesty. ...In view of the subjective requirements made in terms of intent or gross negligence, however, Bjørn Lomborg's publication cannot fall within the bounds of this characterization. Conversely, the publication is deemed clearly contrary to the standards of good scientific practice.
The DCSD cited The Skeptical Environmentalist for:
1. Fabrication of data;
2. Selective discarding of unwanted results (selective citation);
3. Deliberately misleading use of statistical methods;
4. Distorted interpretation of conclusions;
5. Plagiarism;
6. Deliberate misinterpretation of others' results.
Basically, they said Lomborg doesn't know what he's talking about.
