The surface waters around Antarctica were much fresher because cooler polar regions experience greater precipitation relative to evaporation.

-LRB-- NAO) This sea ice then melts in the Sub Polar Atlantic, releasing fresh water into the sub - polar Atlantic waters, which in turn impedes the formation of NADW, which slows down the thermohaline circulation causing warm air not to be brought up from the lower latitudes as far north as previous while in lessening amounts.

Even if ALL the OCEAN ICE around the POLAR REGIONS does «melt», the newly warmed sub-artic regions, verdant with streams and rivers, will take up much of the release to increase the proportion of FRESH LIQUID water available on a now EXTENDED verdant land surface.

However, Earth's polar regions currently experience net precipitation, and the fresh water effect on the ocean density allows the surface to freeze without the need for the entire column of ocean water to reach the freezing point.

As the last major ice age began to recede around 17,000 years ago, polar ice caps in the north and south started to melt, releasing vast quantities of fresh water into the salty oceans, altering natural currents, affecting the environment.

Cold water sinks readily in polar regions, as the surface water tends to be closer to freezing, as well as being fresher from ice melt, and therefore less dense than the inflowing currents, which are in turn are rendered more saline by the fresh water freezing out.

Hauling chunks of polar ice to dry regions to provide fresh water sounds tempting but there are many reasons to reject it, says Olive Heffernan

However enough fresh cold water comes in on the polar currents ensure that overall the deep oceans stay as cold as (but no colder than) the poles.

Scientists believe that increasing global temperatures are causing glaciers — the planet's largest source of fresh water after polar ice — to melt.

97 percent of the water on Earth is salt water, contained in the planet's oceans, seas, and inland salt water bodies, 2 percent of it (fresh water) is locked in the polar ice caps, and the remaining 1 percent is the fresh water we use everyday.
