Ohio Gov. John Kasich (R) knows human activity contributes to climate change, but that doesn't mean he's against it.
"I do believe we contribute to climate change," he said. "We want all the sources of energy. We want to dig coal but we want to clean it when we burn it. We believe in natural gas, we believe in nuclear power, and you know what else I believe in? I happen to believe in solar energy, wind energy, efficiency, renewables."
He later clarified that, "we don't know how much humans actually contribute."
The use of coal and natural gas energy is one of the primary causes of climate change. Burning these fossil fuels releases CO2, which traps heat in our atmosphere and makes the planet warmer. In doing so, humans have managed to help speed up climate change to what may soon be "dangerous" levels.
And despite Kasich's claim, scientists also have a pretty good idea of just how much we're to blame.
"Most of the observed warming since the mid-20th century is due to human-caused greenhouse gas emissions," the Environmental Protection Agency says.
Still, Kasich's confusing position was overshadowed by Florida Sen. Marco Rubio, who managed to quote nearly every single climate denying talking point imaginable.
