The disaster is upon us. The writers of a commentary in The Guardian lay out precisely where we stand:
“For climate change is now an existential risk to humanity. That is, a risk posing large negative consequences which will be irreversible, resulting inter alia in major reductions in global and national populations, mass species extinction, economic disruption and social chaos, unless carbon emissions are reduced far more rapidly than proposed under the Paris agreement. The risk is immediate, in that it is being locked in today by the insistence of Australian conservatives and their global kin to expand the use of fossil fuels when the carbon budget to stay below sensible temperature limits is already exhausted.
It is no longer possible to follow a gradual transition path to restore a safe climate. We have left it too late; emergency action, akin to a war footing, will eventually be accepted as inevitable. The longer that takes, the greater the damage inflicted upon humanity.”
