Stance on Climate Change

“I assert that warm is good for human health and that global warming, even the most extreme estimates, will not create heat illness or death increases and certainly no changes that are more important than the basic public health measures of vector control, water, nutrition, sewage and water quality, and housing quality.” [2]

Key Quotes

“United States Environmental Protection Agency (EPA)-sponsored and funded 'human health effects science' research is unreliable and makes irresponsible and outrageous claims about how air pollution causes thousands of deaths.” [3]

“The internal documents obtained under FOIA revealed the EPA and enviros were looking for a hook and decided the hook they were looking for was the health of children […] Why not? Nothing better to get politicians moving than marching and chanting women in matching t-shirts on a tear, worried about and advocating for their babies.” [7]
