Picture your hometown disappearing. It sounds like something out of a sci-fi movie, but for some U.S. cities, it could become a reality. Climate change, natural disasters, and economic shifts are putting several American cities at risk of vanishing within the next five decades.
This article looks at 12 U.S. cities that might not make it to 2074.
1. Miami, Florida
Miami faces serious flooding risks due to rising sea levels. The city sits on porous limestone, making it hard to build protective barriers. Many neighborhoods already deal with “sunny day flooding” during high tides. By 2070, large parts of Miami could be underwater, forcing residents to move inland.
2. New Orleans, Louisiana
New Orleans is sinking faster than any other U.S. city. The levees that protect it from flooding are struggling to keep up with rising waters. Hurricanes are getting stronger, putting more pressure on the city’s defences. Some experts think New Orleans might need to be abandoned within 50 years.
3. Houston, Texas
Houston is experiencing more frequent and intense hurricanes. The city is also sinking due to groundwater pumping, and its sprawling layout makes it vulnerable to flooding. If these trends continue, parts of Houston could become unlivable by 2070.
4. Phoenix, Arizona
Phoenix is running out of water fast. The Colorado River, its main water source, is drying up. The city’s extreme heat is getting worse due to climate change. Without major changes in water use and heat management, Phoenix might become too hot and dry to support its population.
5. Atlantic City, New Jersey
Atlantic City’s famous boardwalk is threatened by rising seas. The city is also sinking due to natural processes, and stronger storms are eroding its beaches. If sea levels rise as predicted, much of Atlantic City could be underwater by 2070.
6. Honolulu, Hawaii
Honolulu faces risks from rising seas and stronger storms. The city’s beaches are eroding, threatening its tourism industry. Saltwater is seeping into freshwater supplies. By 2070, large parts of Honolulu’s coast could be underwater, forcing people to move uphill.
7. Galveston, Texas
Galveston is extremely vulnerable to hurricanes and storm surges. The island city is also sinking while sea levels rise. Its sand dunes, which offer natural protection, are eroding. Without major interventions, Galveston might not survive the next 50 years of climate change.
8. Charleston, South Carolina
Charleston is dealing with more frequent flooding due to rising seas. The historic city’s low elevation makes it very vulnerable. Stronger hurricanes are also a growing threat. By 2070, Charleston could face daily flooding, making parts of the city unlivable.
9. Norfolk, Virginia
Norfolk is sinking while sea levels rise, causing regular flooding. The city’s naval base, the world’s largest, is at risk. Adapting to higher water levels is extremely expensive. If current trends continue, large parts of Norfolk might have to be abandoned by 2070.
10. Wilmington, North Carolina
Wilmington is threatened by rising seas and stronger hurricanes. The city’s barrier islands, which offer protection, are eroding. Saltwater is intruding into the groundwater. By 2070, Wilmington could face severe flooding and might lose large parts of its coastline.
11. Corpus Christi, Texas
Corpus Christi is at high risk from hurricanes and storm surges. The city’s port and refineries are vulnerable to flooding. Sea level rise is eroding beaches and wetlands. Without major changes, parts of Corpus Christi might become uninhabitable within 50 years.
12. Sacramento, California
Sacramento faces a growing risk of catastrophic flooding. The city relies on aging levees to hold back rising rivers. Climate change is bringing more intense rainstorms. If the levees fail, large parts of Sacramento could end up underwater, possibly forcing abandonment.
