Dunno exactly what the effect is. Gut feel is you need cooler ocean surface for cooler air, and also to reduce formation of extreme weather windstorms.. As for the ecosystem, migration of entire species of fish for cooler climes is definitely not good.

People who seem to think the ocean is for recreational boating and transporting future landfill material from China are in for a rude awakening.
\"The damage caused in these hotspots is also harmful to humanity, which relies on the oceans for oxygen, food, storm protection and the removal of climate-heating carbon dioxide in the atmosphere.\"
This is nature\'s version of an A-bomb blast, about a few trillionths of the reaction rate.

What us the fuss about ocean surface temperatures ?
In warm oceans the temperature varies quite a lot, very warm near the
surface and much colder deeper. There is a quite distinct border
between these sections called the thermocline.
https://en.wikipedia.org/wiki/Thermoclinee
Just below surface down to 100-200 m the temperature is high but
varies greatly due to season, radiation and wind. Below about 1000 m
the water is cold (3-7 C) all year round.
The average ocean dept is about 4000 m, so the average ocean water
mean temperature is closer to 5 C (NOT 20+ C as some alarmists claim).
even
To meaningfully measure the surface water temperatures, in addition to
some satellite measurements also the thermocline dept for each
measurement should be known, since it varies slightly.
In ocean areas where there is a big temperature difference between
surface water and deep ocean water, nutrients can\'t reach the surface
and there are little plankton and hence not capable of feeding a lot
of fish and whales.
In cold waters close to the poles, the thermocline is more or less
nonexistent, i.e. the surface water temperature is nearly the same as
deep water temperatures, nutrients from the bottom can reach the
surface and there will be plenty of plankton, fish and whales. Whales
feed in the cold waters and some swim to the worm waters to give birth
to their offspring only.
