The global warming issue is more than simply answering the question "is it real?" There are actually four questions to answer. First, has the earth on average become warmer over the last century? Second, is it caused by human activity? Third, is it caused by natural effects? Fourth, if the earth is warming, will this be catastrophic or beneficial to humans or other living things?
