- lazyjones 4y agoIt's just scaremongering to mention this and imply that this could actually happen as a consequence of current CO₂ levels. Sea levels have been changing throughout all of human history and they've never drowned a large city instantly because people just resettle over the course of hundreds of years when needed.
