Pennsylvania gubernatorial candidate Scott Wagner's musings on the possible causes of climate change this week is attracting attention across the country.

The Republican state senator and businessman from York told a reporter in Harrisburg on Tuesday that climate change was probably happening but then he advanced several theories not in the mainstream.

"I haven't been in a science class in a long time, but the earth moves closer to the sun every year--you know, the rotation of the earth," Wagner told WITF StateImpact Pennsylvania reporter Katie Meyer.

"We have more people. You know, humans have warm bodies. So is heat coming off?" Wagner said. "Things are changing, but I think we are, as a society, doing the best we can."

He also maintained in the interview that the United States shouldn't worry too much about emissions.

The interview came after Wagner gave a featured speaker talk to county commissioners from Pennsylvania's northern tier counties and natural gas advocates. In that talk, Wagner, owner of Penn Waste, which does trash collection in Lancaster County, reiterated his support of more natural gas drilling in Pennsylvania.

He also advocated for more drilling on public lands in the state.

Asked by LNP about his comments on climate change, Wagner campaign manager Jason E. High, said, "His comments were meant to illustrate that there are a lot of theories about what causes global warming. Scott is running for governor, not to be a scientist, so he will leave it up to scientists to figure out what the cause of global warming is.

"He's focused on making Pennsylvania a responsible steward of the environment while not over-regulating to the point of stifling development and choking businesses out of existence."
