“A perfect self-driving car doesn’t exist yet, nor has the world solved global warming. But it’s surprising that, by the standards that we’d expect in a car to keep its occupants safe, the governments of the world haven’t stepped on the brakes to avoid planetary-scale global warming disaster—a 100-year-storm hitting New York every other year, frequent and massive droughts, inundated coastal cities. In 1995, the Intergovernmental Panel on Climate Change declared that it was ‘more likely than not’ the case that global warming was caused by human activity. By 2001, it had progressed to ‘likely.’ By 2007, it was ‘very likely.’ By 2013, it was ‘extremely likely.’ There’s only one step left in official IPCC lingo: ‘virtually certain.’”
