What was the overall effectiveness of your chosen clean-up methods? estimate how much of the spill you were able to clean using the physical method and using the chemical method. which area was most difficult to clean: the water, the shore, or the feathers? why? what factors would be present in an actual oil spill that was not included in your model? what impacts might your clean-up methods have on the environment?

Combining the emissions released by fossil fuel burning and  the carbon released via land use change, we get a total of 8.7 gt. since the problem states that the oceans "take up" or sequester  2.4 gt carbon  per year, we subtract that value from 8.7 gt, leaving us with 6.3 gt of carbon. since the problem states that 3.4 gt carbon dioxide emissions end up in the atmosphere, the "missing sink" of carbon takes up 2.9 gt, a value we got by subtracting the 3.4 gt amount recorded from the 6.3 gt carbon left available after the oceans sequester the carbon dioxide.
