Rapidly growing cities most vulnerable to impacts of climate change

Combining new UN projections on rates of annual population growth in over 1800 cities with subnational data from our Climate Change Vulnerability Index (CCVI), we assess the threat from climate change over the next 30 years. We found that of the 100 fastest growing cities by population, 84 are rated ‘extreme risk’, with a further 14 in the ‘high risk’ category.
