Mixing humor and science, he entertained the gathering as he made the case for skepticism about climate change.
He began by mocking the degree to which carbon dioxide was treated like a toxic gas by proponents of radical policies on climate change. “Next it will be oxygen, it will be anything that you want on the chemical table,” he joked.
“The Sun is a primary driver of climate change — and has a far greater impact than changes in CO2,” he said, in a slide presented to the packed audience of about 100 conservatives.
