“Absolutely. … I think there’s a lot of overwhelming evidence that suggest that’s the case.”

“I do not. I believe it’s caused by the natural process of the Earth’s cycles.”

“Yes, because the activities we do are hurting the ozone layer thus causing global warming, such as polluting.”

“I do not believe in global warming. It’s raining and it’s cold out right now and it’s still snowing in the winter.”
