A warning from 100 Nobel prize winners.

• Position: Need to address global warming, weaponized world - Brief Article - Editorial

The most profound danger to world peace in the coming years will stem not from the irrational acts of states or individuals but from the legitimate demands of the world's dispossessed. Of these poor and disenfranchised, the majority live a marginal existence in equatorial climates. Global warming, not of their making but originating with the wealthy few, will affect their fragile ecologies most. Their situation will be desperate and manifestly unjust.

It cannot be expected, therefore, that in all cases they will be content to await the beneficence of the rich. If then we permit the devastating power of modern weaponry to spread through this combustible human landscape, we invite a conflagration that can engulf both rich and poor. The only hope for the future lies in cooperative international action, legitimized by democracy.

It is time to turn our backs on the unilateral search for security, in which we seek shelter behind walls. Instead, we must persist in the quest for united action to counter both global warming and a weaponized world.

These twin goals will constitute vital components of stability as we move toward the wider degree of social justice that alone gives hope of peace.

Some of the needed legal instruments are already at hand, such as the Anti-Ballistic Missile Treaty, the Convention on Climate Change, the Strategic Arms Reduction Treaties, and the Comprehensive Test Ban Treaty. As concerned citizens, we urge all governments to commit to these goals that constitute steps on the way to replacement of war by law.
