The damage to human society, and to the planet, from the projected rise of a few degrees of global temperature, while commonly described as apocalyptic, would be minor compared to the results of all-out nuclear war. More to the point, the degree of human responsibility in climate change is more disputed amongst serious scientists than the public is aware, due to the role of such contributing factors as solar variations. But the degree of human responsibility for nuclear weapons is unquestionably total.
The nuclear war peril is manmade, and some of the men who made it can even be named, such as James Byrnes, Harry Truman and General Leslie Groves. The United States government consciously and deliberately created this danger to human life on earth. Faced with the United States’ demonstrated capacity and moral readiness to wipe out whole cities with their devices, other countries built their own deadly devices as deterrents. Those deterrents have never been used, which lulls the public into believing the danger is past.
