Bill Nye spent the 1990s providing science lessons to America’s youth. Now he’s pushing back against the country’s know-nothing adults.

Nye will continue his crusade against misinformation this Sunday on “Meet the Press” with a debate against proud climate change denier Marsha Blackburn, the Republican congresswoman who serves as the vice chair of the House Energy & Commerce Committee.

The host of the once popular after-school staple “Bill Nye the Science Guy” took on committed creationist Ken Ham earlier this month in a debate over the origins of humanity.
