It is hard to keep up with the pace of change in the mind of Donald Trump.

Just hours after announcing he was not going to pursue an investigation of Hillary Clinton over her use of a personal email server, he indicated another important U-turn – this time in regard to climate.

During the campaign, Mr Trump has suggested climate change was nothing more than a "hoax", and that the so-called myth may have been started by the Chinese.

However, in a conversation with journalists from the New York Times on Tuesday, he indicated he had rethought the matter.

Asked if thought human activity was linked to climate change; he responded: "I think there is some connectivity. Some, something. It depends on how much."

He also said he would keep an open mind on whether he would pull the US out of a landmark international climate change deal.

During his presidential campaign, Mr Trump repeatedly said he would withdraw from the 2015 Paris climate accord. But on Tuesday, at a meeting with reporters that itself experienced a U-turn in regard to whether or not it would even take place, he said: "I'm looking at it very closely. I have an open mind to it."
