As climate change intensifies, coastal cities worldwide grapple with the alarming reality of sinking land and rising sea levels. This issue threatens to submerge some of the world’s most vibrant and economically crucial cities, simultaneously changing landscapes and displacing millions of people. It’s a harsh reminder of the threat that global warming poses, with these beautiful areas currently in danger of being unable to survive in the long term.
Jakarta, Indonesia
Jakarta faces one of the most severe cases of subsidence. Parts of the city are sinking at an alarming rate of up to 10 inches per year due to excessive groundwater extraction. Combined with rising sea levels, nearly half of Jakarta could be underwater by 2050, prompting the government to plan a massive capital relocation.
Miami, USA
Miami is an excellent example of the challenges coastal cities face in the United States. Projections show that significant portions of the city could be uninhabitable by 2100, so efforts are underway to combat the rising tides. These include installing extensive pump systems and elevating roads, though these measures are costly and may only offer temporary relief.
Bangkok, Thailand
Rapid urbanization and heavy groundwater pumping exacerbate Bangkok’s sinking. The city’s dense clay soil makes it particularly prone to subsidence. Without significant intervention, large swathes of Bangkok could be submerged by 2030, highlighting just how serious the problem is.
New Orleans, USA
New Orleans is already below sea level and faces risks from subsidence and rising sea levels, which is causing concerns. The city relies heavily on levees and pumping systems to keep water at bay. Still, with increasing storm intensity and sea levels due to global warming, the resilience of these systems is constantly tested, which will cause problems in the long term.
Venice, Italy
Venice is one of the most beautiful locations in the world, and many people visit it due to the water system that they can navigate through boats that pass through the city. However, Venice has been dealing with subsidence and flooding for centuries, and climate change has accelerated the threats. The city’s unique position and heavy reliance on tourism make its flooding issues particularly visible and economically damaging, which impacts those who live and work there.
Ho Chi Minh City, Vietnam
Ho Chi Minh City is experiencing rapid subsidence due to groundwater extraction, urban development, and the natural settling of the Mekong Delta. Projections suggest significant portions of the city could be underwater within the next few decades without drastic intervention, increasing pressure on decision-makers to determine the best course of action.
Alexandria, Egypt
Alexandria is witnessing rising sea levels and subsidence, threatening its rich cultural heritage. As the Mediterranean Sea encroaches, the city is implementing coastal defenses in a bid to combat its problems, but these may not be sufficient in the long run.
Manila, Philippines
Manila is highly susceptible to subsidence and sea level rise due to its location in an area prone to natural disasters, which worsen the situation each time. Efforts are being made to improve urban planning and flood defenses, but the challenges remain immense.
Houston, USA
Houston’s location on the Gulf Coast makes it vulnerable to subsidence, which is enhanced by significant groundwater extraction and the natural settling of its clay soils. Rising sea levels further compound the risk of flooding in this major urban center, which causes worries due to how many people live in the area and could be impacted by this problem in the future.
Dhaka, Bangladesh
Dhaka is another city facing the dual threat of subsidence and rising sea levels. As one of the most densely populated cities in the world, the implications for displacement and economic loss are substantial, which is why strategies are being put in place to combat the issue, even if that only temporarily stops the problems.
Shanghai, China
Shanghai, a major global economic hub, is sinking due to both subsidence and rising sea levels. The city’s extensive infrastructure projects aim to combat these effects, but long-term solutions are still needed.
New York City, USA
Following Hurricane Sandy’s devastation, New York City has invested heavily in flood defenses. But with sea levels rising, continuous efforts are required to protect its dense population and critical infrastructure.
Tokyo, Japan
Tokyo employs advanced technology to monitor and combat subsidence and rising sea levels. The city’s approach includes building sea walls and creating sophisticated drainage systems to prevent flooding, demonstrating that attempts are being made to fight this situation.
Lagos, Nigeria
Lagos is experiencing rapid urban growth but faces significant subsidence due to groundwater extraction. Rising sea levels further threaten this bustling metropolis, so urgent infrastructure improvements will be needed, especially if the area continues to develop.
Amsterdam, Netherlands
Amsterdam has a long history of managing water through its extensive canal and dike system, which flows through the city. But rising sea levels and subsidence present new challenges that require innovative solutions to keep the city dry, especially when the water is everywhere.
Samut Prakan, Thailand
Just south of Bangkok, Samut Prakan is sinking even faster, putting it at immediate risk of flooding. The city’s industrial base and residential areas are increasingly vulnerable to rising tides.
Norfolk, USA
Norfolk, home to a significant naval base, is grappling with subsidence and rising sea levels. The city’s military and civilian infrastructure is at risk, prompting significant investments in resilience projects.
Chittagong, Bangladesh
Like Dhaka, Chittagong faces severe risks from subsidence and rising sea levels. The city’s coastal location makes it particularly susceptible to frequent flooding and storm surges.
Los Angeles, USA
While not sinking as rapidly as some East Coast cities, Los Angeles still faces significant challenges from sea level rise. The city’s extensive coastal infrastructure and densely populated areas require ongoing adaptation efforts.
Honolulu, USA
Honolulu, surrounded by the Pacific Ocean, is experiencing rising sea levels that are threatening its beaches and urban areas. Efforts to protect this island paradise include building sea walls and restoring natural buffers like coral reefs.
