Renowned Physicist Stephen Hawking:
“As we stand at the brink of a second nuclear age and a period of unprecedented climate change, scientists have a special responsibility, once again to inform the public and to advise leaders about the perils that humanity faces,” he said. “As scientists we understand the dangers of nuclear weapons and their devastation effects, and we are learning how human activities and technologies are affecting climate systems in ways that may forever change life on Earth."
