On the contrary, large bodies of water are currently shrinking substantially on timescales that humans can experience directly. The Aral Sea is probably the best example. The Great Salt Lake is another. Lake Mead was created by the Hoover dam in the 1930's, and now it's well on its way to turning back into desert. https://brilliantmaps.com/aral-sea/ https://brilliantmaps.com/aral-sea/
