Sixty years after philosopher Bertrand Russell and physicist Albert Einstein convened a group of leading intellectuals in London to draft and sign a manifesto in which they highlighted the perils posed by nuclear weapons, this generation’s forward-looking thinkers have released an updated version of the document—one that puts the looming climate crisis on par with the threat of nukes and calls for “the creation of a new sustainable civilization on a global scale.”

The Declaration on the 60^th Anniversary of the Russell-Einstein Manifesto, published Thursday, reads in full:

The declaration has been published in the form of a petition that anyone can sign. The effort is being coordinated by Foreign Policy in Focus, the Asia Institute, and World Beyond War.

Among the first to sign onto the document are: political theorist Noam Chomsky; environmentalist and anti-capitalist Naomi Klein; CIA whistleblower John Kiriakou; former NSA technical director William Binney; and anti-nuclear activist Helen Caldicott, who said in a statement: “It was the Russell-Einstein manifesto on the threat of nuclear war 60 years ago that started me upon my journey to try to abolish nuclear weapons.”
