A) is incorrect 

The present-day decrease in formation of Arctic sea ice and the melting of the Greenland Ice Sheet are major concerns given the possible impact on the climate system. Which one of the following statements best describes this impact? Melting of the Greenland ice sheet and less sea-ice formation will increase the Earth's albedo in the polar region, which will lead to increased warming. Melting of the Greenland ice sheet and less sea-ice formation will decrease the heat deficit in the polar regions and weaken the latitudinal temperature gradients, which in turn directly affect the rate of deep-water formation. Melting of the Greenland ice sheet and less sea-ice formation will lead to a major shift in circulation patterns of the ocean gyres, which in turn decrease the ability of the surface ocean water to sink to the deeper parts of the ocean. Melting of the Greenland ice sheet and less sea-ice formation will decrease the ability of the polar atmospheric circulation cell to transfer heat energy. Melting of the Greenland ice sheet and less sea-ice formation will 'freshen' the surface ocean in the polar region making it less dense, decrease the rate of deep-water formation and lead to a slowing of the oceanic conveyer belt.
