Critical Reasoning (CR) | Re: Global warming has contributed to a rise in global sea level

Global warming has contributed to a rise in global sea level not only because it causes glaciers and ice sheets to melt, but also simply because when water is heated its volume increases. But this rise in global sea level is less than it otherwise would be, since over the years artificial reservoirs have been built all around the world that collectively contain a great deal of water that would otherwise reach the sea.
