Coastal flooding could affect an additional 1.4 million people by 2200, new research suggests. The result, Palmer says, is that sea-level rise is ‘locked-in’ for centuries to come. “The Wash and the Humber Estuary stand out as ‘hot spots’ for future coastal flood risk across all scenarios.” This would give as much time as possible to detect and react to future changes indicative of more extreme future sea-level rise. The worst sea-level rise outcomes could be mitigated by “pursuing concerted global efforts to reduce greenhouse gas emissions, in line with the Paris Agreement goals,” Neal concluded.
