Stephen Hawking, the late and legendary physicist, predicted a few years ago that humanity only had 100 years to find a new planet to colonize – or face extinction. Maybe he was optimistic. The world is already on fire.
The destruction wrought by human-caused climate change is evident all over the world: catastrophic fires, unprecedented heat waves, historic droughts. In the United States alone, more than 100 million people in 28 states are currently on alert for dangerously hot weather. The lakes are drying up in the west. In Europe, the heat is causing the infrastructure to burn. In May, India and Pakistan suffered a heat wave so violent that birds fell from the sky.
