Although natural changes alone do not explain the increase in global climate. As David KC Jones would say, “…human influences do, for the most part, only alter rates of change” (Jones 127). Some of the activities that people do every day have a huge impact on the main causes of global warming. As the world changes, the chances of humans causing global warming increase. According to Dale Jamieson, “there is no way to accurately assess all possible impacts [of global warming]” (Jamieson 144). There will most likely always be something that causes global warming. With new data showing how different human activities affect global temperature, it's not just natural phenomena that cause global warming.
