Millions face long-term coastal flooding risk in UK without climate action, scientists warn
Summary
Scientists warn that up to 13 million people in the UK could face coastal flooding in the long term due to rising sea levels caused by climate change. Even if current efforts to reduce carbon emissions succeed, more people will be at risk by 2200 and 2300, making proactive planning and flood defenses essential.Key Facts
- Up to 13 million people in the UK might be at risk of coastal flooding in the long term.
- Even if current global carbon-cutting promises are met, 1.4 million more people will be at risk by 2200, and 1.7 million more by 2300.
- Sea levels around the UK have already risen about 20 cm in the last century and are rising faster.
- By 2100, sea levels are expected to rise another 40 to 60 cm, putting an additional half-million people in danger.
- Some areas, like Lincolnshire and the Humber estuary, face especially high risks.
- A worst-case scenario could cause up to 15 meters of sea level rise by 2300, flooding large parts of London and other areas.
- Scientists say flood defenses and managed relocation of communities will be necessary to handle future risks.
- The study did not include future storm surges, population growth, or changes in flood defenses, meaning the actual risk could be higher.
