Trump 'believes climate is changing', says UN ambassador Nikki Haley

White House has dodged declaring president's view on climate change, but Haley says leaving Paris accord 'doesn't mean we don't care about the environment'

Donald Trump "believes the climate is changing" partly because of pollution, according to the US ambassador to the United Nations, Nikki Haley.

Speaking on the CNN programme State of the Union, due to air on Sunday, Haley was seeking to define the president's thinking about climate change in the wake of his announcement that the US will leave the Paris climate accord, joining Syria and Nicaragua as one of three non-signatories.
