Rick Perry, a Texas governor, says that climate change is non-existent and that more and more scientists are challenging the claim that human activity has resulted in global warming (“Perry’s Global Warming Statements,” 2011). Actor Danny Glover blames the 2010 Haiti earthquake on global warming and criticizes a climate summit in Copenhagen for failing to create a significant response to the perils of climate change (Brent, 2010). Politicians, actors, and many other public figures make science-related statements. How do you know which statements are truly based in science, and which are not?
Last week, you explored the nature of science and learned about the scientific method. Knowing the fundamentals of the scientific process helps you to evaluate science-related information. Obtaining information from reliable scientific sources—which may not always be a politician or celebrity—is also critical.
For this week’s Assignment, you respond to a scenario that requires you to identify and analyze scientific facts about global warming. You also describe the carbon cycle processes of photosynthesis and cellular respiration and relate these to global warming.

To prepare for this Assignment:
You are a participant in a city council debate about global warming. During the debate, council members make conflicting statements about climate change, and most members are unsure about the sources of their information. The city council members realize that they do not have the scientific facts on global warming. You have been selected to conduct research on this topic and submit a report that includes these scientific facts. The council also wants you to explain the carbon cycle and how it relates to global warming.
Write a report of two or more pages that presents the scientific facts about global warming and explains what the carbon cycle is and how it relates to global warming. Your report should address the following:
Part 1: The Carbon Cycle
Compare and contrast photosynthesis and cellular respiration by answering the following questions:
Part 2: Scientific Facts About Global Warming
Identify at least three scientific facts related to global warming that include:
Part 3: How the Carbon Cycle Relates to Global Warming
Explain how the carbon cycle relates to global warming, describing at least two implications of climate change for biological systems.
Be sure to cite all references in APA format.
