Will sea level rise if the polar caps melt?

Get a container. A tall one will work, like a tumbler.
Fill it about 3/4 full with tap water.

Add ice until the container is full but not so much that the container
overflows or the ice protrudes above the top. Place a cover over the
container to minimize evaporation, a saucer will do. Place the
container on a table and mark the side of it where the water level
appears. Make sure to choose the flattest part of the meniscus away
from any ice contact with the wall.

Let the ice melt.

Once the ice is completely melted, check the new water level.

Tell me again why sea level will rise?

Well, the south polar caps and other glaciers are on land, you say?
What is the volume of the ice on land, precisely? What is the relative
proportion of that volume of ice to the total volume of liquid water
in the oceans? What is the precise total surface area of the oceans?
When that 'precise' volume of ice is spread over the surface area of
the oceans how thick will it be? If you cannot answer these questions
Al Gore, you cannot predict sea level rise.
