An Associated Press article on climate change said, “Some of the ice shelf’s disappearance was probably during times when the planet was 36 degrees Fahrenheit (2 degrees Celsius) to 37 degrees Fahrenheit (3 degrees Celsius)warmer than it is today.” What mistake did the reporter make?
Assuming there is no feedback and greenhouse effect, estimate Earth's
average temperature when there is a 5W/m² increase in solar radiation. (Use the
solar radiation in two-box model)
How does the greenhouse effect work? Is it beneficial or harmful to humans?

- Q2: Stirling et al. (2008) reviewed a paper titled as: "Polar bears of western Hudson Bay and climate change: Are warming spring air temperatures the "ultimate" survival control factor?" by Dyck et al. and cited the papers that had analyzed the temperature from 7 weather stations in the Western Hudson Bay through a large period of time. Stirling et al. mentioned that Dyck et al. have not used the research works that recorded and analyzed data during a long period. What type of bias are Stirling et al. pointing out in their review?arrow_forwardWhat determines the climate on Earth is basically related to incoming radiation from sun and moon...true or falsearrow_forwardThe graph shows the estimated annual amount of heat that is transported from the equator toward the poles at different latitudes on Earth. The graph shows three curves- the amount of heat transported by the ocean, the amount of heat transported by the atmosphere, and the total amount of heat transported by the ocean and atmosphere combined. Using this data and what you know about atmosphere and ocean circulation, try to answer the questions below. The amount of heat energy transported is given in Petawatts (PW). One Petawatt = 1,000,000,000,000,000 watts, so this is a LOT of energy! To put this in context, the monthly electric use of an “average” home in PA was 831 kilowatt hours in 2006. Look at what happens between 20º N and 40º N. 1. How does the total amount of heat that is transported change and by how much? 2. Remember, when the value increases, it means that heat is being absorbed by that part of the system, and when the value decreases, heat is being lost by that part of…arrow_forward
