Billionaire media mogul and New York's former mayor Michael Bloomberg was reappointed to the role of U.N. Secretary-General António Guterres' special envoy on climate ambition and solutions on Friday, in preparation for the United Nations' next major climate summit.
Bloomberg's return to the forefront of global climate efforts comes just weeks after the start of U.S. President Joe Biden's administration, which has made it a priority for the United States — the second-biggest emitter, after China, of carbon dioxide, methane and other greenhouse gases — to serve as a global leader in confronting global warming.
