UNITED NATIONS: The United Nations on Friday hit back at Donald Trump after he vowed to scrap the Paris climate deal if elected US president, saying the agreement was critical to saving the planet. “The Paris agreement is one of the key achievements that world leaders have made in the critical fight that is designed to make sure that this planet is habitable for all of us, for generations to come,” UN spokesman Farhan Haq said. Trump had in the past said he was “not a big fan” of the Paris deal and that he would seek to renegotiate it, but on Thursday he declared that he would simply scrap it altogether. UN Secretary-General Ban Ki-moon considers the Paris deal as his proudest accomplishment during his 10-year tenure. However, Ban has no plans to reach out to Trump to try to educate him on the benefits of the Paris deal, according to his spokesman.
