What Are Sinking Cities?

The Climate Crisis Beneath Our Feet

Here is a Summary of the Article I read in BBC Science Focus. For years, climate discussions have focused on rising sea levels as the primary threat to coastal communities. But new research suggests another danger may be even more urgent: cities themselves are sinking.

Scientists say land subsidence — the gradual sinking of the ground — is affecting many heavily populated coastal and river-delta cities, sometimes faster than the ocean is rising. This trend could dramatically increase flood risks and infrastructure damage worldwide. 

Why Cities Are Sinking

Several factors are driving this phenomenon:

Groundwater extraction: Pumping water from underground aquifers can cause soil to compact and sink. Urban development pressure: Heavy buildings and infrastructure compress soft soils. Natural geological processes: Sediment compaction and tectonic shifts also contribute. Climate impacts: Rising seas compound the risks when land is already subsiding. 

These combined forces mean some cities face a “double hit” — sinking land plus rising oceans.

Cities Most at Risk

Major urban areas built on river deltas or coastal plains are particularly vulnerable. Examples often cited include:

New Orleans, Bangkok, Jakarta, and Several large U.S. coastal cities

In some places, subsidence is already increasing flooding risks and threatening infrastructure like roads, railways, and buildings. 

Why This Matters Now

Unlike sudden disasters, subsidence happens gradually — often just millimeters per year. That slow pace can make the danger easier to ignore, even as risks quietly accumulate.

However, long-term impacts may include:

More frequent flooding Infrastructure instability Coastal habitat loss Increased economic and insurance costs

Experts say monitoring land movement should become a routine part of urban planning.

The Bigger Climate Conversation

This issue doesn’t replace sea-level rise concerns — it amplifies them. When cities sink while seas rise, flood risk accelerates dramatically.

The takeaway: climate resilience isn’t just about oceans — it’s also about what’s happening underground.

📍 What It Means Locally (Triangle Perspective)

While Raleigh isn’t a coastal city, regional climate planning still matters:

Flood-resilient infrastructure planning Sustainable groundwater management Smart urban development strategies

Understanding global climate trends helps local communities prepare for future environmental challenges.

🔎 Final Takeaway

The climate crisis isn’t only about melting ice caps or rising oceans. Sometimes the biggest threat is quieter — the slow sinking of the ground beneath major cities. Of course our President does not care to acknowledge the issue, and thanks to Tom Howarth of BBC Science Focus Magazine

UK urged to adapt buildings and infrastructure for severe climate change impacts by 2050

The UK's Climate Change Committee (CCC) has warned that current government plans to protect buildings and infrastructure against extreme weather are insufficient given the expected impacts of global heating. By 2050, heatwaves are expected in at least four out of every five years in England, drought... [More info]

Transportation Adaptation to Climate Change

Without radical climate-change adaptations, movement of people and goods will soon become severely limited. Recent studies estimate that climate-related damage to transportation infrastructure could exceed $1 trillion by 2050. #ClimateAdaptation #TransportResilience

Transforming Transportation for a Changing World

The accelerating deterioration of Earth’s biosphere demands fundamental changes in how we approach transportation. From coastal infrastructure threatened by rising seas to rail lines buckling under extreme heat, our existing transportation systems face mounting challenges that require innovative solutions and comprehensive adaptation strategies.

Climate Impacts on Infrastructure

The scale of climate impacts on transportation infrastructure is staggering. Research by the American Society of Civil Engineers projects that climate-related damages will surpass $1 trillion by 2050 (ASCE 2021). Coastal transportation networks are particularly vulnerable, with studies indicating that up to 60% of coastal infrastructure will face risks from sea-level rise and storm surges by 2100 (Dawson et al. 2016).

Heat impacts present another critical challenge. Extreme temperatures cause rail buckling and road surface degradation, leading to billions in annual repair costs. Chinowsky et al. (2019) estimate that heat-related damage to transportation infrastructure will become a major economic burden by mid-century.

Innovative Materials and Design Solutions

To address these challenges, engineers are developing climate-resilient materials and adaptive design approaches. The Arizona Department of Transportation’s pioneering use of rubber-modified asphalt demonstrates the potential of advanced materials to enhance infrastructure stability (Rodezno et al. 2020).

The Netherlands offers another inspiring example with their innovative floating roads concept, enabling transportation infrastructure to adjust to changing water levels (Rijkswaterstaat 2018). Such flexible design approaches will become increasingly crucial as environmental conditions become more volatile.

Alternative Transportation Methods

Diversifying transportation options strengthens system resilience. Electric and hydrogen-powered vehicles represent a crucial step toward reducing fossil fuel dependence while integrating with renewable energy systems. Norway’s rapid transition to electric vehicles demonstrates the feasibility of large-scale transportation electrification (Norwegian EV Association 2021).

Active transportation infrastructure, particularly walking and cycling networks, provides low-carbon mobility options that remain functional during energy disruptions. Copenhagen’s extensive bicycle infrastructure network exemplifies climate-resilient urban transportation (City of Copenhagen 2019).

Supply Chain Adaptations

The resilience of supply chains becomes increasingly critical as environmental conditions deteriorate. Distributed storage facilities and flexible routing systems enhance supply chain stability. Amazon’s network of fulfillment centers illustrates the potential of distributed logistics (Hoberg and Alicke 2019).

Local production and shorter supply chains reduce vulnerability to transportation disruptions. The concept of “smart specialization” in regional economies can enhance stability while maintaining efficiency (Foray 2018).

Urban and Rural Considerations

Urban transportation systems require focused adaptation due to high population density and infrastructure concentration. Transit-oriented development reduces transportation vulnerability while improving accessibility. Singapore’s integration of land use and transportation planning serves as a model for resilient urban mobility (Meng et al. 2018).

Rural areas face unique challenges, including dispersed populations and limited resources. Queensland, Australia’s flood-resistant road design guidelines offer valuable insights for rural adaptation (Queensland Government 2019). Alternative access methods, such as small aircraft and autonomous vehicles, become vital for remote areas.

Emergency Transportation Planning

As environmental disruptions increase, emergency transportation planning becomes critical. Florida’s evacuation planning system provides valuable lessons for large-scale population movements (Florida Division of Emergency Management 2021). The United Nations Humanitarian Response Depot network highlights the importance of pre-positioned transportation resources (UNHRD 2020).

Conclusion

Reviewing the literature on transportation adaptation gives one the same old “too little too late” feeling. The 200-year minimum planning period is not being applied. If it were, the worst-case prospects would generate much stronger preparations. (I included more discussion of this issue in Silent Earth (Rogers 2025).
