    The presence of a huge ice sheet helps support itself by changing the amount of energy the Earth receives.


    Question 13 options:

    2. Relevant equations
    none

    3. The attempt at a solution
    Ice sheets have high albedo, therefore earth gets less solar energy?

    Sounds OK to me.

    Although discussing it in terms of "Earth receives" is an exaggeration, we talk about the local situation. It can be easily seen even on just a few square feet of snow how prominent is the effect of having clean white surface vs "dirty" snow.
