I need help answering these questions

1. Define a coupling and a feedback loop. Provide an example of a positive feedback loop that includes atmospheric temperature (please do not use one we discussed in lecture). Does this feedback loop act to stabilize or destabilize air temperature? Use notations for couplings used in the text/lecture in your illustration.

2. What are three major uses/applications of a quantitative global climate model?

3. What is the amount of solar flux that the Earth receives from the sun at the top of the atmosphere (include units)? Has this been changing during the past 4.5 billion years, if so - how so? What other information do you need to know calculate the Te or effective temperature of the Earth (assuming the Earth is a true blackbody).

4. Describe the mathematical relationship between the amount of solar flux a planet receives and the distance from its sun. How much would the flux change if the Earth were 2 times the current distance from the sun? Use the value from question 4 to calculate that flux.

5. What question does Wien's law help to answer? Why is it important to quantifying the net radiative balance of the Earth?
