"I've seen first hand rising sea levels over the course of my life," as salt flats replaced pine trees, Sanford states on his campaign website. He was part of a group of House Republicans that put forth a resolution in 2017 urging their fellow members to take the issue seriously.
"There's a larger debate on what to do about it, and that's a much more complex debate, but it's like with Alcoholics Anonymous, if you don't even recognize the fact that you have a problem, you're never going to address the problem," the congressman told reporters at the time.
But the candidate doesn't believe that the U.S. should enter into international agreements that may give unfair treatment to other countries with high levels of greenhouse gas emissions, such as India and China. For example, Sanford does not support the Kyoto Protocol.
