“As a geologist, I love Earth observations, but it is ridiculous to tie this objective to a ‘consensus’ that humans are causing global warming when human experience, geologic data and history, and current cooling can argue otherwise. ‘Consensus,’ as many have said, merely represents the absence of definitive science. You know as well as I, the ‘global warming scare’ is being used as a political tool to increase government control over American lives, incomes and decision making.”

Harrison Schmitt (American geologist, retired NASA astronaut, university professor)
