The U.N.'s new envoy for climate action, former New York Mayor Michael Bloomberg, said Monday that President Donald Trump can become "a great leader" if he changes his mind about global warming and keeps the United States in the Paris climate agreement.
The billionaire media mogul expressed hope that Trump will listen to his advisers, look at the data on climate change, and support the 2015 Paris accord aimed at reducing greenhouse gas emissions.
Bloomberg spoke during a ceremony at which U.N. Secretary-General Antonio Guterres gave him the new title of U.N. special envoy for climate action, handing him the job of spurring international action to help curb global warming.
A longtime activist for clean energy and a green economy, Bloomberg was appointed U.N. special envoy on cities and climate change by then U.N. chief Ban Ki-moon in January 2014. Since then, he has been traveling around the United States and the world campaigning for a reduction in carbon emissions.
