"I think that we probably are better off leaving science to the scientists and focusing on what we're really good at, which is theology and morality," he said.
In an interview on "Fox News Sunday," Santorum attempted to defend his remarks. Host Chris Wallace pointed out that Santorum talks plenty about climate change, even though he doesn't even have a background in science, like the pope does.
"I guess the question would be, if he shouldn't talk about it, should you?" Wallace asked.
Santorum argued that politicians "have to make decision with respect to our public policy that affect American workers." He added that the pope "can talk about whatever he wants," but it might not be the best issue for him to "use his moral authority for."
The ball's in your court, Chris:
"He would say he's protecting the earth," Wallace replied.
"I would say that that's important thing to do, but I think there are more pressing problems confronting the earth than climate change," Santorum said.
Of course, we've already established that Santorum is not a scientist and the pope is.
