Diplomat tells climate scientists to speak out



Former Canadian Ambassador to the United Nations Stephen Lewis challenged scientists at a climate change conference to “move from dispassionate observation to passionate advocacy” and make their views on the threat posed by greenhouse warming known to fellow citizens and political leaders.

Lewis, who chaired a multinational conference on climate change last June in Toronto, delivered a principal address December 7 in Washington, D.C., to the Second North American Conference on Preparing for Climate Change. The conference was sponsored by the Climate Institute, an international environmental organization composed of scientists and policymakers. After retiring from the Canadian government last summer, Lewis became a special assistant on Africa to the U.N. Secretary-General, Javier Perez de Cuellar.
