At a campaign appearance in Myrtle Beach, SC, surging Republican candidate Carly Fiorina addressed a standing room only crowd, talking about a suite of issues, including climate change.

“A single nation acting alone will make no difference at all,” Fiorina said, echoing her concern that a global effort is needed to combat the problem.

Fiorina also addressed Democratic frontrunner Hillary Clinton’s announcement she is opposed to the Keystone XL pipeline.

“The truth is, everyone agrees, if the Keystone pipeline were implemented, global greenhouse gas emissions would decline, not increase,” Fiorina said.
