Textbook Question
Chapter 10, Problem 59IF
The Politics of Global Warming. The current scientific case for global warming seems quite strong, but the topic nonetheless generates significant political controversy. Why do you think that is the case? Do you consider global warming to be primarily a scientific issue or a political issue? Explain.

CO2 and planetary warming: understanding Earth’s complicated atmosphere Mars has an atmospheric pressure of 6 mbar (compared with Earth atmosphere pressure of 1013 mbar), 96% of which is CO2. The average calculated temperature of Mars is -57°C, whereas the actual average temperature is -55°C so that the amount of warming due to CO2 is only 2°C. On the other hand, the average calculated temperature of Earth, with 0.4 mbar of CO2, is -19°C, whereas the actual average temperature is 15°C so that the amount of warming due to CO2 is 34°C, much greater than that on Mars, which has higher CO2 concentration. Explain how this is possible.

- Hi! PLEASE ANSWER IN C# and explain each step so I can understand please (: The last experts did not answer in C# (reject my question if you can't). The controversial issue of global warming has been widelypublicized by the film “An Inconvenient Truth,” featuring former Vice President Al Gore. Mr. Goreand a U.N. network of scientists, the Intergovernmental Panel on Climate Change, shared the 2007Nobel Peace Prize in recognition of “their efforts to build up and disseminate greater knowledgeabout man-made climate change.” Research both sides of the global warming issue online (you might want to search for phrases like “global warming skeptics”). Create a five-question multiplechoicequiz on global warming, each question having four possible answers (numbered 1–4). Be objectiveand try to fairly represent both sides of the issue.
