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