No humidity of the air does not affect melting… much… well if the air was the same temperature, and pressure, which means “All other things being equal”, then the increased density should increase the rate of melting.
Troll though ? you know that humidity is either relative or absolute, so why mention the ocean, with its 100% absolute humidity … but if not, you aren’t asking here ! You also know the difference between effect and affect, and thats not really for this thread either.
