Climate change: 'We've created a civilisation hell bent on destroying itself – I'm terrified', writes Earth scientist
'At some point in the future, the technosphere could even function without humans. We worry about robots taking over human’s jobs. Perhaps we should be more concerned with them taking over our role as apex consumers.'

When Will Climate Change Make the Earth Too Hot For Humans?
The Earth has experienced five mass extinctions before the one we are living through now, each so complete a slate-wiping of the evolutionary record it functioned as a resetting of the planetary clock, and many climate scientists will tell you they are the best analog for the ecological future we are diving headlong into. Unless you are a teenager, you probably read in your high-school textbooks that these extinctions were the result of asteroids. In fact, all but the one that killed the dinosaurs were caused by climate change produced by greenhouse gas. The most notorious was 252 million years ago; it began when carbon warmed the planet by five degrees, accelerated when that warming triggered the release of methane in the Arctic, and ended with 97 percent of all life on Earth dead. We are currently adding carbon to the atmosphere at a considerably faster rate; by most estimates, at least ten times faster.
