The links provided here allow you to explore global climate change, carbon dioxide concentrations, and future implications. Read each article and summarize in a short paragraph the main points of the article. In addition to a paragraph on each article, tell me what you think about increased amounts of carbon dioxide and the effects on climate. Do you think there are better ways to predict the future climate? Are we doing all we can to understand past climate variability? Answer these questions the best you can. Do not worry about "right" or "wrong" answers, this is a thinking exercise.
