4/21/2008 2 Tunes Are Changing. .. U.S. Secretary of State Condolezza Rice, September 2007 – “It is our responsibility as global leaders to forge a new international consensus on how to solve climate change . . . If we stay on our present path, we face an unacceptable choice eithe we sacrifice globa economic Presentation to Seniors in Chemical Engineering The University of Oklahoma April 15, 2008 unacceptable choice: either we sacrifice global economic growth to secure the health of our planet or we sacrifice the health of our planet to continue with fossil-fuelled growth.” Anthropogenic climate change is not a new theory… Presentation to Seniors in Chemical Engineering The University of Oklahoma April 15, 2008 It is the confirmation of a prediction: In the late 1890s, Svante Arrhenius theorized about a warming climate due to the burning of coal. In 1938, Guy Stewart Callendar asserted that warming of the 19 th century forward was due to a rise in CO 2 .
