In Into the Clear Blue Sky, climate scientist and chair of the Global Carbon Project Rob Jackson explains that we need to redefine our goals. As he argues here, we shouldn't only be trying to stabilize the Earth's temperature at some arbitrary value. Instead, we can restore the atmosphere itself in a lifetime--and this should be our moral duty. Restoring the atmosphere means reducing the amount of greenhouse gases in the air to pre-industrial levels--starting with super-potent methane--to heal the harm we have done. Emissions must be cut, first and foremost. But to safeguard a livable planet for future generations, we must repair the damage we have caused.
