UNITED NATIONS, Sept. 23 (UPI) -- The United Nations climate summit, convening Tuesday, is anticipated to prompt a global change of course for action on the environment.
It comes after a rally Sunday by tens of thousands of people in New York, and in other cities, calling for development of a climate change deal by world leaders. The summit also comes after a U.N. Intergovernmental Panel on Climate Change warned the world is reaching a point it can no longer limit global warming to two degrees Celsius above temperatures in the pre-industrial era.
