previously obscure, the dcsd became embroiled in controversy after its january 2003 decision that the 2001 book "the skeptical environmentalist" by bjørn lomborg was "clearly contrary to the standards of good scientific practice", due to the author's systematically biased choice of data, and "objectively" was scientifically irredeemable, but lomborg himself could not be "subjectively" convicted of intentional or gross negligence. lomborg had argued in his book that claims by environmentalists about global warming, overpopulation, deforestation, and other matters are not scientifically substantiated. the dcsd further held that because of lomborg's lack of scientific expertise, he had not shown intentional or gross negligence, and acquitted him of the accusations of scientific dishonesty.
