Make this look like I didn’t copy Water heated at the Equator flows north
to cold high latitudes at the surface of the
ocean, where it becomes colder. When it
cools, the deep ocean becomes denser
and sinks. To take its place, more warm
surface water flows in, cools, sinks, and
the pattern continues. But this trend may
be modified by melting Arctic sea ice.
The influx of freshwater from the melting
ice makes seawater less salty and thus
less thick at high latitudes as the Planet
begins to warm and Arctic sea ice melts.
In reality, data shows that over the past
few decades, the North Atlantic has
already become fresher.
