Climate change: I am inevitable. Robert Downey Jr.: I am Iron Man. That's basically what went down during the opening keynote at Amazon's new re:MARS tech and innovation conference in Las Vegas. Avengers actor Robert Downey Jr. made the very Tony Stark-like announcement that he'd be launching a new organization focused on solving environmental woes using artificial intelligence and other advanced technologies. "Between robotics and technology, we could probably clean up the planet significantly, if not entirely, within a decade," he said on Tuesday night.
