Big companies to Trump: 'Don't quit Paris climate pact'

An open letter released at high-level UN climate talks in Marrakesh called on the US president-elect to back "continued US participation in the Paris Agreement, in order to provide the long-term direction needed to keep global temperature rise below 2C," or two degrees Celsius (3.6 degrees Fahrenheit).

Trump has called global warming a "hoax", and said he would "cancel" the agreement.
