Textbook Question
Chapter 10, Problem 49IF
Greenhouse Lessons. While it seems unlikely that human activity could cause a runaway greenhouse effect on Earth, we could still cause the climate to warm substantially. Do you think we can learn anything valuable about our potential effects on Earth’s climate by studying the climate histories of Venus and Mars? If so, what? Defend your opinion.

Briefly summarize the evidence linking human activity to global warming.
What are its potential consequences?
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. Next, write an application that administersthe quiz, calculates the number of correct answers (zero through five) and returns a message to theuser. If the user…

- One source of information about Mars has been the analysis of meteorites from Mars. Since no samples from Mars have ever been returned to Earth from any of the missions we sent there, how do we know these meteorites are from Mars? What information have they revealed about Mars?arrow_forwardWhich of the following is least reasonable regarding the concept of a habitable zone? Group of answer choices M-type stars have wider habitable zones than G-type stars. It is a region around a star where liquid water could be found on a planet's surface. The habitable zone of a less massive star would be closer to the star. In the course of millions of years, our habitable zone will slowly shift from Earth to Mars. The Galactic habitable zone cannot be too close to the Galactic center because the radiation from the bright stars and supernovae in the crowded inner part of the Galaxy would probably be detrimental to life.arrow_forwardEddies- Describe the many ways that eddies might occur.
