Nuclear Weapons


Science for Peace began in the 1980s as a group of scientists concerned about the danger of nuclear war. This focus continues through the nuclear weapons working group, educating the public and decision-makers about the catastrophic humanitarian effects of nuclear warfare and promoting nuclear disarmament.[nd_options_spacer nd_options_height=”15″][vc_column_text css_animation=”none”]”An understanding of what nuclear weapons do invalidates all arguments for their continued possession and requires that they urgently be prohibited and eliminated.” – Dr. Tilman Ruff
