  1. Introduction HNRS330 Global Climate Change: The Scientific Bases and Responsible Societal Responses Dr. Hengchun Ye Department of Geosciences and Environment Spring 2014

  2. "Global warming, along with the cutting and burning of forests and other critical habitats, is causing the loss of living species at a level comparable to the extinction event that wiped out the dinosaurs 65 million years ago. That event was believed to have been caused by a giant asteroid. This time it is not an asteroid colliding with the Earth and wreaking havoc: it is us.” Bill Clinton: The science is clear. Virtually all climate experts agree that we must reduce global greenhouse gas emissions by 80 percent by the year 2050. If we fail, the worst consequences of climate change threaten to increase the severity of health epidemics,

  3. The big questions are: • How sensitive is climate to greenhouse gas buildup? • What will climate change look like regionally and locally?
