QUESTION 26

What is the definition of feedback in global warming terms?

When the earth fills out a comment card saying it doesn't like what we are doing to it.

When the earth's general population gathers to rally awareness towards Global Warming.

When one quantity is changed causing a second quantity to change as well, then the second quantity creates a change in the first quantity.

None of the above

QUESTION 34

Which of the following below would increase the Earth's albedo?

increase in ocean depth

increase in ice sheet surface area

increase in volcanism

all of the above

none of the above

Explanation / Answer

8) The early atmosphere was mostly carbon dioxide with little or no oxygen, which is evident in the isotopic signature of various geological features. Also it was because of carbon dioxide that earth's temperauture was much higher than present value.

26)  Climate change feedback is important in the understanding of global warming because feedback processes may amplify or diminish the effect of each climate forcing, and so play an important role in determining the climate sensitivity and future climate state. Feedback in general is the process in which changing one quantity changes a second quantity, and the change in the second quantity in turn changes the first.

34)  Albedo is a measure of the reflectivity of a surface. The albedo effect when applied to the Earth is a measure of how much of the Sun's energy is reflected back into space.ice sheets or caps at poles are well reflectors of sulight. If there is increase in the surface area of ice sheets more sunlight energy will be reflected back in the space and the earth's albedo will increase.
