Donald Trump's climate change denial guru says US President faces 'impending disaster'

Donald Trump’s administration is facing “impending disaster” because of its failure to ditch policies designed to reduce global warming, according to a former aide who is a leading climate science denier. Myron Ebell was in charge of the US Environmental Protection Agency (EPA) during the transition from Barack Obama’s presidency to Mr Trump’s and was important enough to be granted a visit to Downing Street after Republican billionaire took office.
