Conway . It identifies parallels between the global warming controversy and earlier controversies over tobacco smoking , acid rain , DDT , and the hole in the ozone layer . Oreskes and Conway write that in each case `` keeping the controversy alive '' by spreading doubt and confusion after a scientific consensus had been reached , was the basic strategy of those opposing action . In particular , they say that Fred Seitz , Fred Singer , and a few other contrarian scientists joined forces with conservative think tanks and private corporations to challenge the scientific consensus on many contemporary issues .   The George C. Marshall Institute and Fred Singer , two of the subjects , have been critical of the book . Other reviewers have been more favorable .

Scientific consensus on climate change <=SEP=> There is currently a strong scientific consensus that the Earth is warming and that this warming is mainly caused by human activities. This consensus is supported by various studies of scientists' opinions and by position statements of scientific organizations, many of which explicitly agree with the Intergovernmental Panel on Climate Change (IPCC) synthesis reports.  Nearly all actively publishing climate scientists (97–98%) support the consensus on anthropogenic climate change, and the remaining 2% of contrarian studies either cannot be replicated or contain errors.
