Ex-mayor Michael Bloomberg already has a new gig at his own media company, but one post-mayor job is not enough for the tireless billionaire, so he’s picking up a second. Unless something goes wrong at the last minute, he’ll be working for the United Nations as special envoy for cities and climate change, Reuters reports. He’s already president of the board of the C40 Cities Climate Leadership Group, so this isn’t much of a stretch. Plus the commute is easy enough. Should work out fine.
