Glaciers are still one of the primary reasons for lowered sea/water levels because the water increasingly becomes bound up as ice as the glacier grows.

The change in sea level from the advance or retreat of glaciers is so minimal the change in sea level would be unmeasurable.

Now, if you could get ALL the ice/glaciers everywhere on the planet to melt all at the same time, then you could cause a measurable change. Since that would only happen if we moved the Earth a whole bunch closer to the Sun.....

Let me ask you this. Are sea levels currently RISING or FALLING ?

The effect of glaciers on the compression/decompression is measurable and is done by using fixed base receivers to collect GPS data that indicate changes in elevation. About 1/4th inch per year in some cases. The sea levels will lower with massive glaciation because of the cycle of water, evaporation, rain. When huge glaciers that covered half of the northern hemisphere formed ocean water evaporated and fell as snow on those glaciers thus locking up water that would otherwise fall back as rain into oceans and their feeder rivers. This also took many millenia but the last ice age from start to finish covered many millenia.
