The air would heat up to nearly the same temperature. It takes a lot more energy to change the water temperature compared to air, so heating up the air doesn't cool off the water very much (which is why radiators circulate hot water to heat the air in your house).
This heating would start with the air above the oceans, but air circulates quickly, so it would spread all over the planet pretty quickly. You didn't say anything about latitude. If the ocean is the same temperature everywhere, then the air becomes the same temperature everywhere.
So every species that can't survive at, say, 150 degrees Fahrenheit would die.
A lot of water would evaporate. The hot wet air would form massive hurricanes. There might be a drop in sea level for the first few months, because evaporation would be happening over a much larger surface than the melting of glaciers. But over a few years all ice would melt, which would raise sea level 200 feet and flood the coastlines.
Eventually the excess heat would bleed off into space. The Earth would return to an equilibrium where absorbed solar energy equals emitted geothermal energy. That would probably be within 10 degrees of current temperatures, but it's hard to guess what the albedo would be of a planet with more clouds and no ice.
