With 70% of the worlds surface water, when the temperature goes up evaporation will go up. There is a lot more surface affected by evaporation than that affected by melting.
Warm air will hold more water vapor than cold air.
Now is there a brain here that can tell me the net effect between melting ice and evaporated water in relation to increases in temperature?
Yes, It is REVERSELY proportional.
The more heat the more ice melts, and if you keep up the heat or increase it, the melting ice turns into water vapor.
Smartaleck (but true) answer number TWO:
Sun melts Ice.
Clouds (water vapor) provide cover from Sun.
It takes the Sun a LONG LONG TIME to melt ice.
It only takes a SECOND for a CLOUD to drop the temperature by 10 degrees.
