In just 30 years, cities around the world will face dramatically higher risks from extreme heat, coastal flooding, blackouts and food and water shortages. Cities face dramatic rise in heat, flood ...
By 2050, coastal flooding in the US is likely to rise tenfold to four "moderate" flooding events per year. That forecast is even without storms or heavy rainfall. [ 221 ] [ 222 ] In New York City , current 100-year flood would occur once in 19–68 years by 2050 and 4–60 years by 2080. [ 223 ]

Looking further ahead, Climate Central said nearly 4.8 million Americans live in areas anticipated to be at risk from a major coastal flood in 2100, and around 20 percent of those are children ...
Drivers, processes, and impacts of sinking cities [1]. Sinking cities are urban environments that are in danger of disappearing due to their rapidly changing landscapes.The largest contributors to these cities becoming unlivable are the combined effects of climate change (manifested through sea level rise, intensifying storms, and storm surge), land subsidence, and accelerated urbanization.
