Albedo approximate values glacial ice: 0.80 ocean surface: a-0.07 marine stratus clouds: highly variable, but as060 is a reasonable number. desert sand a 0.40 grasslands: 0.20 bare rock: 0.30 scenario #1: as the earth warms, we observe that most of the glaciers and ice sheets on earth have been ice sheets, with most temperature to change as a result of this change in albedo? why would you expect to see getting smaller. about 10% ofthe land surface of earth is oovered by glaciers and of this ice on greenland and antarctica suppose that all of this ioe were to melt. how would this change the earth's albedo? and how would we expect the earth's this type of change? (you will eed to use some of the numbers in the table to answer this question) scenario #2 : many ines of evidence indicate that about 6000 years ago, the sahara desert was not a desert. but was nstead a vast savannah (a dramatic evidence of this 'green sahara" period include fossils of giraffes and elephants, animals that do not live in the sahara today because t is a desert. when this green savannah ecosystem dried and became the enormous desert that it is today, what effect did this have on the earth's albedo? and how do you expect that this would you expect to see this type of change? (again, you will need to use some of the numbers in the table to answer this question) scenario ส3: "you have lived in san francisco for lorgy uprobably know that a thick deck of low-y gdo dsonen forms over the ocean of' the cali macoast wecal his featur" a marine stratus cloud deck (stratus clouds are a type of low-lying cloud that have a large horizontal extent and a uniform base height) stratus clouds tend to be pretty reflective. the albedo of clouds in general is quite variable, and depends on how thick the clouds are, but lot's estimate the aibedo of these stratus clouds as o o.6. now le's suppose something were to happen that decreased the amount of stratus clouds that formed off the califonia coast (we will come back to what might do this later in the semester) how would you expect this to change the table below albedo of the earth? and how would this change the average tomperature of the earth? explain your logic. (to answer this question you will also need the albedo of the ocean surface from the
