Fox Business reporter Tracy Byrnes says that climate change is overblown because the temperature of the Earth “basically hasn’t changed much since the Ice Age.”

During his Tuesday show on the Fox Business Network, habitual climate-change denier Stuart Varney pointed to an op-ed by Princeton Professor William Happer as evidence of another “nail in the coffin of global warming hysteria.”

“CO2 is not a pollutant,” Happer wrote. “Life on earth flourished for hundreds of millions of years at much higher CO2 levels than we see today. Increasing CO2 levels will be a net benefit because cultivated plants grow better and are more resistant to drought at higher CO2 levels, and because warming and other supposedly harmful effects of CO2 have been greatly exaggerated. Nations with affordable energy from fossil fuels are more prosperous and healthy than those without.”
