Ok, so my question is rather dumb and I apologise in advance.
If I have 500ml of warm water, and I place exactly 500ml of ice into said water, when it melts will it make it up to 1L?, and if so why is global warming such an issue because isn’t there more water on earth than there is ice, so wouldn’t it just melt away. (I’m not taking away from the fact global warming I not an issue) I was just making something that needed to cool quick so I put ice in it and it made me curious!!

In terms of global warming and sea level rise, you’re not quite asking the question right. If you have a glass with water and ice in it, regardless of the amount of each, and you mark off where on the glass the water level is, as the ice melts the water level will not change. This is because the ice is floating in the water and displaces the same amount of water that it will represent when melted, even with the rest of the ice’s volume sticking up above water (like an iceberg). The issue for sea level rise is ice that is not floating, to simulate that it would be like placing the ice in a funnel above the glass of water. As that ice melts it will flow down the funnel and rise the level of water in the glass. So the problem for sea level rise is the melting of ice that is on land, of which there is a lot.
