“The claim that cigarette smoking causes lung cancer has not been scientifically proven………..it is a reductionist error and not keeping with the current theories of cancer causation to attempt to assign each cancer to an exclusive single cause…………the use of results from flawed population studies to frighten people by attributing large numbers of death yearly to smoking may be misleading and is most regrettable……….that emotionalism can override objective analysis is illustrated by the headlines………despite millions of dollars spent by the government on smoking and health-related research, many questions about the relationship between smoking and disease remain unanswered…………indeed, many scientists are becoming concerned that preoccupation with smoking may be both unfounded and dangerous – unfounded because evidence on many critical points is conflicting, dangerous because it diverts attention from other suspected hazards.”
-from Smoking and Health: 1964-1979: The Continuing Controversy, published in 1979 by the Tobacco Institute
“There is no experimental data to support the hypothesis that increases in hydrocarbon use or in atmospheric carbon dioxide and other greenhouse gases are causing or can be expected to cause unfavourable changes in global temperatures, weather, or landscape…….any number of things can influence earth’s temperature. The list includes volcanic eruptions, variations in the amount of energy received from the sun, El Niños, and La Niñas – all of which are natural………we understand public anxiety about climate change, but are concerned that many of these much publicized predictions are ill-informed and misleading……….the media continue to uncritically accept and vigorously promote shrill global warming alarmism………after hundreds of millions of dollars spent on climate modeling, and decades of screaming headlines, we have no more certainty today about global warming prediction than we did decades ago………..if even a small part of the money spent trying to reduce carbon dioxide emissions were spent instead on fighting hunger or disease in Third World countries, millions of lives could be saved.”
-from the various articles on the Heartland Institute’s global warming page
