The increase in meltponds in Arctic regions is an example of
A) positive feedback, because the melt ponds absorb more solar energy than the ice did.
B) positive feedback, as the melt ice freezes it increases the area of ice.
C) negative feedback, because the ponds reflect more sunlight than ice and therefore absorb less energy.
D) negative feedback, as the ice melts the water freezes, increasing the amount of ice.

Question

Quizplus · Accepted Answer

Meltponds in Arctic regions are known to have a positive feedback, as they absorb more solar energy than the ice did. This leads to a reduction in the albedo, which causes more melting and more meltponds. This process accelerates the overall melting of the Arctic ice, leading to more warming and more meltponds.
