In the past few months alone, our foes have used a firestorm to force the total evacuation of a city of 90,000 in Canada, drought to ravage crops to the point where southern Africans are literally eating their seed corn, and floods to threaten the priceless repository of art in the Louvre. The enemy is even deploying biological weapons to spread psychological terror.” TNR’s Bill McKibben argues that we’re under attack from climate change — and our only hope is to mobilize like we did in WWII.
