WHY is the arctic shrinking and the antarctic growing?



It's getting warmer.



Arctic sea and land ice is melting. Any fresh water from melting land

ice is quickly lost from the area, carried south and mixed with

warmer, saline water.



Antarctic land ice is melting. Increased fresh water largely remains

within Antarctic waters, circling eastwards, making formation of sea-ice

easier.


It isn't getting warmer on land, and even If it did its got a long way to warm before it produces fresh water.

If there is any drop in salinity of the southern ocean, and you need to prove that first, the fresh water must come from another source.
