A member of US President-elect Donald Trump's transition team says a belief in man-made climate change may one day be comparable to believing the Earth is flat.
Mr Trump, who once said climate change was "a hoax invented by the Chinese", has been coy when questioned on the subject since winning the race for the White House.
But alarm bells have gone off for many as he appointed a number of cabinet members who have questioned the scientific validity of man-made global warming.
That's been exacerbated further as his transition team were found to have requested the names of Department of Energy employees who had been involved in discussions regarding the global climate.
One of the driving forces behind that request was Anthony Scaramucci, a Trump aide and managing partner of investment firm SkyBridge Capital - and he was questioned over that in television interview with CNN.
"I know the current President [Barack Obama] believes that human beings are affecting the climate. There are scientists that believe that that's not happening," he told host Chris Cuomo.
According to NASA, 97 percent of climate scientists agree that global warming is occurring and that it's caused by humans, which was a point Mr Cuomo addressed - but Mr Scaramucci's played that down in his response.
"There was overwhelming science that the Earth was flat and there was overwhelming science that we were the centre of the world," he said.
"We get a lot of things wrong in the scientific community."
Later in the interview, Mr Scaramucci pointed out he was not a scientist, and honestly didn't know what was causing a change in climate.
He addressed the issue further in a series of tweets, saying he was "not a climate change denier" and that he does think it possible that global warming is caused by humans.
