A newly published study includes estimates that, within 30 years, around 23 million people will be impacted by coastal flooding (https://www.theguardian.com/environment/2020/jul/31/extra-23-million-people-could-face-coastal-flooding-within-30-years-even-with-emission-cuts-study-says). This will be caused by a combination of elevations of sea level, storm surges and extreme tides. The damage to coastal properties could exceed $14.2tn (as many of the world's major cities are located by the sea). Scarily, the predicted effect on such coastal locations will, it is claimed, still occur even if ambitious curbs on greenhouse gases are brought in immediately. What happens if we continue to dither and delay is something that I wouldn't like to contemplate.
