According to the Intergovernmental Panel on Climate Change 2007 report, the global temperature could increase by up to six degrees Celsius by the end of the century. Global warming is a serious issue. We need to start combating it now. Here at UW-Madison, we should work toward eliminating all greenhouse-gas emissions on our campus. The College Sustainability Report Card for 2009, created by the Sustainable Endowments Institute, gave UW-Madison a grade of â??B.â? Good, but not great. This indicates that we need to do more on campus to reduce our ecological footprint and create a more sustainable and carbon-neutral environment.
