Lab Activity 3 – Global WarmingNSCI 102This lab activity consists of three parts. First, you will watch the 2006 documentary “An Inconvenient Truth.” Next, you will access the companion web site for the film and use a simple calculator to estimate your own carbon emissions. Finally, you will summarize what you have learned.If you do not wish to rent the DVD, there are two copies available for your viewing on the Black Hawk College campus. See the instructions posted with the assignment for locations and hours. Part 1: An Inconvenient TruthWhile watching the film, answer the questions below and take note of concepts that are presented inthe documentary that are familiar to you from the textbook readings. If there are any ideas presented that conflict with what you’ve read in the text, note those as well.According to Al Gore, why do many politicians hold the issue of global warming “at arm’s length”?The 6thgrade geography teacher who scoffed at the idea that the eastern coast of South American and the western coast of Africa was reflecting the assumptions of the time. What is a current assumption that many people have about global warming that “just isn’t so”?When did Al Gore first become interested in issues of carbon dioxide emissions and climate change?Measurements of atmospheric carbon dioxide concentrations show that there is a yearly fluctuation. Why does the “curve” go up and down each year?
