Sincere question. IF; Matter can neither be created nor destroyed; all of the H2O that has ever existed on planet Earth currently exists; Fill a glass of water and ice cubes to the brim and as the ice melts going from solid to liquid the level remains the same; then -Must we worry about rising seas from melting glaciers? Perhaps the melting of frozen snow/ice that covers land would lead to sea level rise. Does melting glaciers floating in the seas contribute to significant water level rise?
