Marco Rubio Can't Name A Single Source Behind His Climate Denialism

Sen. Marco Rubio (R-Fla.) got some pushback on Tuesday for his comments on Sunday that he does not believe "human activity" is impacting climate change.

Rubio was speaking at the National Press Club on Tuesday when he was asked by an attendee at the event via a moderator: “What information, reports, studies or otherwise are you relying on to inform and reach your conclusion that human activity is not to blame for climate change?”

The rising GOP star and presumptive 2016 presidential candidate seemed to dodge the question, instead focusing on what climate proposals he would deem acceptable.

“I’ve never disputed that the climate is changing, and I’ve pointed out that climate to some extent is always changing, it’s never static,” Rubio said.

"There are things that we can do to become more efficient in our use of energies, there are things we can do to develop alternative sources of energy, there are things we can do to be better stewards of the energy resources that we have like natural oil and gas," Rubio told the crowd -- while affirming that he could not support proposals that would "ban" all coal and carbon emissions.

Rubio made the comments a day after NASA released a report that claims the West Antarctic ice sheet is melting in an "unstoppable" way.

CORRECTION: A previous version of this story misidentified the West Antarctic ice sheet as the "West Arctic."
