A July 2026 study warned that rising sea levels could put up to 13 million people in the United Kingdom at long‑term risk of coastal flooding, with the coastline already 20 cm higher than a century ago and projections of another 40‑60 cm by 2100. The authors highlighted worst‑case scenarios of a 15‑metre rise by 2300 and called for stronger flood‑defence measures and strategic retreat. A later report in the same month expanded the outlook, estimating that by 2200 an additional 1.4 million UK residents could face flooding, a 25 % increase over current risk, and noting that sea levels might triple by 2300. The study was paired with Cincinnati, Ohio’s Climate Migration Readiness Plan, which prepares for up to 525,000 new residents by 2050—many expected to relocate from vulnerable U.S. coastal areas—through denser housing, expanded transit, and reduced fossil‑fuel reliance. Together the snapshots illustrate how projections of sea‑level rise are increasingly linked to concrete migration planning in both the UK and the United States. ## Timeline ### 2026-07-31: UK sea‑level rise risk and US city climate migration plan underscore growing climate displacement UK researchers predict 1.4 million more people at flood risk by 2200, while Cincinnati rolls out a plan to house up to 525,000 climate migrants by 2050. 2 sources. https://clstr.news/cluster/uk-sealevel-rise-risk-and-us-city-climate-migration-plan-underscore-growing-climate-displacement ### 2026-07-25: Sea‑level rise threatens up to 13 million homes in the United Kingdom A study warns that up to 13 million UK residents face long‑term flood risk from sea‑level rise, with 40‑60 cm projected by 2100 and worst‑case 15 m by 2300, urging stronger protection and retreat plans. 2 sources. https://clstr.news/cluster/sealevel-rise-threatens-up-to-13-million-homes-in-the-united-kingdom --- Cite as: Sea‑level rise and climate displacement.
