ABSTRACT
The atmosphere is kind. It takes the carbon dioxide (CO2) and other heat-trapping greenhouse gases that humans create and disperses them equally all over the world. But that is also its cruelty. The accumulation of these waste gases over the decades, disproportionately from industrial countries but increasingly from some rapidly developing ones, is overwhelming the planet’s energy balance and heating up its surface. This accumulation must end, but how that will happen is hard to imagine. The mechanisms needed must engage all humanity in ways that are manifestly fair to all.
