The recent floods in Valencia have left a heart-wrenching toll on the region, where days of relentless rain culminated in a disaster of unprecedented scale. Over 200 lives were lost, communities were displaced, and critical infrastructure was left in ruins. This has crippled the area, and it will take a lot of time, money and people’s effort to get the communities out of an emergency situation, let alone back to a new normality. 

Even though it is obvious that flooding events, such as the one now, have been occurring chronically in the Eastern Mediterranean region of Valencia in Spain from September to November, human-induced climate change has exacerbated these events, making them more intense and frequent and accompanied by unforeseen warm core storms. 

The impacts went beyond only climate change; local land-use planning, stormwater and wastewater management, and inadequate, disjointed river basin management limited the area’s resilience to extreme weather events. Urban development on floodplains further heightened flood risks, especially in areas exposed to preferential river overflow pathways, simulated in hydrological models with intense rainfall and a 100 to 500 return period*.

The Need for Proactive Action 

Climate change is fueling more heavy rainfall events and unforeseen extreme weather phenomena at the same time that sea-level and global warming temperatures rise, driving more coastal marine flooding. In the particular case of the nearby region of Valencia, where the Magro and Jucar Rivers overflood, the Albufera Lake, one of the most ecologically valuable landscapes of this peninsula, helped as a buffer to retain tonnes of sludge and water before draining them directly into the sea.

This disaster highlights the urgent need for real-time meteorological-hydrological-hydraulic modelling encompassed with alert systems to improve readiness for extreme and unforeseen climate-related emergencies. Strong adaptation and mitigation strategies that include a holistic understanding of the entire river basin, land-use spatial pattern, hydrological infiltration and retention rates, and defence systems are also needed. 

Data and modelling services are essential here, as they incorporate information to support forecasting and bring in multiple critical scenarios to react and wisely manage the coastal territory, including both the land-use spatial planning and the hydraulic defence and active infrastructure for flood management. CoCliCo is an example of one such service specific to marine surges and coastal risk from sea-level rise. Our platform informs people, from citizens to decision-makers, about present and future coastal flooding risks from sea-level rise and supports adaptation and mitigation efforts to counter this. 

Information is only one piece of the puzzle. For effective adaptation and mitigation, we need decision-makers to use all of this science-backed knowledge to take action. COP29 offers an opportunity to progress, particularly on climate finance and funding, and to protect those on the front lines of these climate impacts.

The Impact of Climate Change on Events Like the Valencia Floods

The Valencia flood disaster was catastrophic, causing extensive damage to critical infrastructure, including homes, public buildings, vehicles, power networks, roads, and highways. Tragically, many lives were lost, and numerous people suffered serious injuries. Recovery will take not only weeks but months, or even years, to reach a “new normal.” Hydraulic engineering experts estimate that the flooding across the Turia, Jucar, and Magro river basins in the Valencia region, Spain, has caused damages exceeding 30,000 million euros (ABC, 2024).

It was fueled by climate change: abnormally high sea surface temperatures in the Atlantic are increasing atmospheric moisture, and the higher temperature in the western Mediterranean region favours the formation of such extreme thunderstorms. Thus, these high-altitude isolated depressions, known locally as DANA, drew in moisture from warmer-than-usual waters, leading to intense downpours. As projected decades ago, such extreme rainfall events fueled by climate change have become more intense and frequent as the atmosphere and oceans continue to warm (Earth Observatory, Climate Central, ClimaMeter). Analysing the precipitation, we find that extreme rainfall on October 29th lasted approximately 24 hours, with accumulations reaching up to 450 mm/m² in certain areas. The average precipitation across the affected area was 100 mm/m², placing this event within the statistical range of a 100- to 500-year return period*, meaning it was possible but very unlikely. The upper and middle sections of the Poyo watershed saw rainfall levels higher than ever recorded for such a short period. Heavy rainfall was concentrated in the upstream and midstream areas of the Magro River, while the downstream area received much less. Similar extreme events have been recorded, such as storms on October 14, 1957, and the Tous Dam incident in 1982 (accessed via AEMET and avamet). We now know these events are not isolated incidents but part of a larger global pattern influenced by human-caused warming.

The Impact of Planning and Management 

While climate change fueled extreme weather, factors such as land-use planning and infrastructure management compounded the storm’s impact.

Local land-use planning also influenced the severe effects on the region, intensifying the damage caused by extreme weather. Key contributing factors included patterns in spatial planning, land-use decisions, and standard practices in stormwater and wastewater management (Marcos-Garcia et al., 2023, Machi-Felici, 2008). “We are in a floodplain. We have built more than we should over the last 25 years (…)” (Javier Machi, dean of the Valencian Community College of Civil Engineers, translated in La Vanguardia)

In addition, a lack of integrated, transdisciplinary approaches to river basin management limited consideration of the watershed’s geomorphological and hydrological dynamics. This challenge is especially pronounced in areas with frequent torrential rain, where urban development has encroached on critical floodplain areas, further worsening flood risks.

Protecting Coastal Communities from a Range of Coastal Risks 

Although the disaster that took place in Valencia was due to extreme thunderstorms and rainfall, we know coastal communities face a combination of threats from climate breakdown. The coastal flood hazards of sea temperature and level rise (due to ice melting), thermal expansion of the ocean, and, in some regions, coastal subsidence are also increasing extreme sea levels. This trend is not yet perceived by many because sea levels are rising by approximately 4mm/year globally. Yet, scientists know that we are locked into centuries of sea-level rise and are already seeing the effects in Europe. The historically 1-in-100-year coastal floods are projected to increase by x10 before 2050 in many locations along the Mediterranean and Atlantic coasts and along almost all remaining European coasts by the end of the century, under a low emissions scenario. 

Unlike heavy rainfall, which will stop increasing when climate warming has stabilized, sea-level rise will continue for centuries due to the slow response of the ocean and ice sheets to contemporary climate warming. That’s why we need to simultaneously mitigate climate breakdown through global decarbonisation and nature-based solutions while introducing effective adaptation strategies to protect the most vulnerable communities and regions. What’s more, higher sea levels and heavy precipitation resulting in large run-off volumes can cause compound flooding in low-lying coastal areas, as was the case in the catastrophic floods in Venice in November 2019.

CoCliCo is a research project that aims at providing information on where is most at threat from sea-level rise and what the most cost-effective measures are to implement and hopefully prevent such destruction, such as flood defences, room for the river, and even retreating from the highest-risk zones. Importantly, the scale of adaptation needed in coastal areas offers an opportunity to leave more space for sediments and ecosystems and contribute to limiting coastal biodiversity losses, an issue of concern whose implications are still largely underestimated and receive little media attention (Machi-Felici, 2024). 

The Need for Long-Term Vision

The loss in Valencia highlights a critical need for prioritizing coastal resilience, particularly as urbanization in vulnerable areas grows. For centuries, dating back to Roman times, these floodplain areas have remained largely unprotected, with development steadily encroaching on these fragile, flood-prone landscapes. Governments and local authorities now have the challenge of defining adaptation strategies that protect people and at-risk infrastructure and anticipate future disasters and responses, such as coastal nature-based solutions and grey infrastructure (e.g., dikes) while leaving opportunities for coastal ecosystems and using limited adaptation funding wisely. 

The DANA volunteer groups were primarily made up of citizens from across the country who came on their own to assist those suffering in this critical situation. The experience in this region demonstrated that the most powerful response came from ordinary people, driven by compassion and solidarity, especially in the absence of a coordinated effort from higher-level authorities. At COP29, leaders must advance on climate finance and demonstrate commitment to meaningful adaptation and mitigation to prevent the worst of climate breakdown.CoCliCo supports evidence-based planning to aid communities and decision-makers in preparing for rising coastal risks in Europe. But these investments are just a starting point; a full response requires a long-term vision and policy alignment with the scale of climate challenges we face.

* The return period is a way to describe how likely an event (like a flood or storm) is to happen over time. It’s usually measured in years and tells us, on average, how often we might expect a certain event to be exceeded. 

  • A 500-year return period flood has a 1-in-500 chance (or 0.2%) of occurring in any year.
  • A 100-year return period flood means that, on average, there’s a 1-in-100 chance (or 1%) of a flood of that size happening in any given year. Within any given 100-year period, however, there is a 66% chance that it will be exceeded. 

Publication: Comparing built-up area datasets to assess urban exposure to coastal hazards in Europe

/0 Comments/in , /by

As coastal hazards rise with climate change, European cities face increasing exposure to flooding. A recent CoCliCo study published in Nature compares several built-up area datasets to assess this exposure and highlights the need for precise data in urban planning.

Information on urban land use beyond the urban-rural divide can enhance assessments of coastal hazards by refining damage estimates and supporting adaptation planning. However, inconsistent definitions of “urban” in past studies have resulted in varying exposure estimates. This study examines the exposed population and built-up area across four settlement types defined by different datasets.

Key Insights:

  1. Urban Vulnerability: The study compares datasets, revealing significant discrepancies in estimating urban areas at risk from coastal flooding.
  2. Data Accuracy: Precise data helps decision-makers better plan for future flood risks and enhances climate adaptation strategies.
  3. Resilience Planning: Comprehensive urban assessments help ensure European cities’ preparedness against rising sea levels and storm intensities.

Conclusion:

Our study highlights the critical importance of selecting the appropriate built-up area data for accurate population and exposure assessments. The choice of dataset can significantly affect estimates, with variations in population exposure reaching up to 65%(127 million people). This emphasises the need for careful consideration of dataset characteristics, including spatial resolution and classification thresholds, to ensure the data’s suitability for its intended purpose. Furthermore, refined urban classifications, beyond the simple urban-rural divide, are essential for more precise risk and damage assessments. Especially in rapidly growing suburban areas. Future research should explore more nuanced urban distinctions and assess the impacts of other contributing data variables to enhance the accuracy of exposure estimates.

Understanding Sea Level Rise Projections and the Role of Scenarios 

/0 Comments/in , /by

The 21st century has witnessed an unprecedented rise in global mean sea level (GMSL), a trend that is projected to continue till at least 2100. The Intergovernmental Panel on Climate Change (IPCC) reports that GMSL rose faster in the 20th century than in any prior century over the last three millennia. The rise has been attributed to ocean thermal expansion and mass loss from glaciers and ice sheets, with minor contributions from changes in land-water storage. 

However, these projections come with a degree of uncertainty. The future sea level rise could be influenced by earlier-than-projected disintegration of marine ice shelves, abrupt onset of marine ice sheet instability, and faster-than-projected changes in the surface mass balance and discharge from Greenland. These processes are characterized by deep uncertainty due to limited process understanding, limited availability of evaluation data, uncertainties in their external forcing, and high sensitivity to uncertain boundary conditions and parameters. 

Why Do We Use Scenarios in Climate Change Science for Projections?

Scenarios are used in climate change science to understand the potential future impacts of climate change. They provide a structured way to explore and communicate complex, uncertain future conditions. In the context of climate change, scenarios are not predictions or forecasts, but rather plausible descriptions of how the future might evolve. 

What are Shared Socioeconomic Pathways (SSPs)? 

Shared Socioeconomic Pathways (SSPs) are scenarios used by climate researchers to project the potential future states of societies and economies. They consider various factors like population growth, economic development, education, urbanization, and the rate of technological change. The IPCC has defined five SSPs, each representing a different trajectory for societal development in the absence of climate policy intervention and a different level of challenges to mitigation and adaptation. 

How are SSPs related to Sea Level Rise and Coastal Management? 

SSPs play a crucial role in understanding the potential impacts of sea level rise and formulating effective coastal management strategies. They help us understand how different societal pathways might influence greenhouse gas emissions, which in turn drive global warming and sea level rise. By understanding these potential future states, we can better plan for and manage the risks associated with sea level rise. 

Sea Level Rise on each SSP in Europe 

Each SSP represents a different potential future, and thus, a different potential impact from sea level rise. For instance, under SSP1-1.9, where warming is held to approximately 1.5°C above 1850-1900 levels by 2100, the projected sea level rise is lower compared to SSP5-8.5, a high reference scenario with no additional climate policy, where emission levels are highest. 

In Europe, as in the rest of the world, the impact of sea level rise will vary significantly depending on the SSP. Coastal areas will face increased risks from flooding, erosion, and other coastal hazards. The ability of these areas to adapt to these changes will depend on a variety of factors, including the rate of sea level rise, the physical characteristics of the coast, and the societal and economic pathway followed. 

In conclusion, understanding and considering SSPs is crucial in our fight against climate change. They provide us with a framework to understand potential future societal and economic conditions, helping us prepare for and mitigate the impacts of sea level rise. As we continue to refine these pathways and our understanding of their implications, they will remain an essential tool in our climate change arsenal.

First Ever European Climate Risk Assessment (EUCRA)

/0 Comments/in , /by

“Europe is not prepared for rapidly growing climate risks”, EEA reports, after publishing the first-ever European Climate Risk Assessment (EUCRA). The assessment builds upon the IPCC and the latest insights from many European projects, such as CoCliCo. The report recognises many gaps in our knowledge but highlights just how much we know. 

European Climate Risk Assessment (EUCRA)

Europe faces escalating climate risks, including extreme heat, droughts, wildfires, and flooding, with projections indicating worsening conditions even under optimistic global warming scenarios. The European Environment Agency (EEA) has introduced the first-ever European Climate Risk Assessment (EUCRA) to guide policymakers in identifying priorities for climate change adaptation.

The assessment highlights a lag in policy and adaptation actions, urging urgent measures as incremental changes may not suffice. Southern Europe is identified as a hotspot for multiple risks, such as wildfires and agricultural impacts. The EUCRA identifies 36 major climate risks across ecosystems, food, health, infrastructure, and the economy. Urgent action is particularly crucial to conserve ecosystems, protect against heat, floods, and wildfires, and ensure the viability of solidarity mechanisms.

Our colleagues Elco Koks (VU Amsterdam) and Paul Sayers (Sayers and Partners) co-authored, Chapter 15: Major Disruptions of Critical Infrastructure, with contributions from Jaroslav Mysiak (CMCC) and Anna Pirani (CMCC). 

Key Messages from Chapter 15:

Climate Threats to Critical Infrastructure:

Europe’s vital infrastructure faces increased exposure to extreme weather events, posing risks to transport, energy, and communication services.

Interconnected Network Vulnerability:

Infrastructure assets are interconnected, and failures at one point can cascade across the system, necessitating a holistic approach to climate resilience.

Adaptation Deficit and Urgency:

Ageing infrastructure in Europe has a significant adaptation deficit. Proactive measures are crucial, emphasising adapting before system failures occur.

Proactive Adaptation and Transformation:

Long-term infrastructure resilience requires proactive adaptation, with some sectors and locations needing transformational changes rather than incremental adjustments.

Data-Driven Decision-Making:

Better data and analytics are essential for understanding asset conditions, assessing risks, and informing adaptation strategies, including regulatory stress tests.

Policy Implementation and Responsibility:

Policies for infrastructure resilience must account for current and future climatic hazards, with clear responsibilities assigned to owners and managers for effective implementation.

In summary, ecosystems, food production, human health, infrastructure, and the economy face severe risks, requiring immediate attention. There is a strong need for collaboration among EU Member States and involvement of regional and local levels for coordinated action. The EU’s role in addressing knowledge gaps, legislation, governance structures, monitoring, funding, and technical support is crucial for enhancing climate resilience. The EUCRA report serves as a strategic tool, synthesising existing knowledge to effectively support policymakers in navigating climate challenges.

3. Economic Value of Beaches: A striking revelation from the study is the economic value associated with maintaining the present-day width of beaches. By 2100, the research shows that neglecting erosion can result in underestimating flood damage by a factor of two. Conversely, preserving the current beach width can avert a staggering AUD 785 million worth of assets from flood damage.

4. Resilience and Adaptation: Unlike some coastal ecosystems that face challenges in adapting to changing conditions, beaches exhibit remarkable resilience. The study underscores the ability of beaches to adjust to shifts in sea levels and storm intensities rapidly, highlighting their adaptive potential in the face of climate-driven changes.

Insights for Decision-Makers:

1. Beyond Flood Protection: The research extends its focus beyond flood protection, emphasizing the multifaceted benefits of beaches. Besides their crucial role in mitigating flood risks, beaches provide significant recreational benefits, adding economic value to their conservation.

2. Trade-off Analysis: One of the study’s notable contributions is elucidating the trade-off between the benefits of maintaining current beach conditions and the associated nourishment costs. Decision-makers now have a valuable tool for evaluating the cost-effectiveness of beach conservation strategies under different scenarios.

3. Future Planning Considerations: With rising sea levels and increasing storm intensities on the horizon, understanding the economic value of beaches becomes paramount for informed climate adaptation planning. The study’s insights give decision-makers a nuanced understanding of how beaches contribute to climate resilience.

Conclusion:

This research marks a significant step forward in unravelling the hidden benefits of beaches in climate adaptation. By emphasizing the economic value of beaches, the study contributes to the scientific understanding of coastal dynamics and provides evidence for private investment and financial instruments supporting beach restoration efforts.

Publication: Adaptation to multi-meter sea-level rise should start now

/0 Comments/in , /by

As our planet faces the realities of climate change, one of the most pressing challenges is the rising sea levels, posing a significant threat to coastal areas worldwide. A recent study led by Gonéri Le Cozannet and colleagues, including members of the CoCliCo team, highlights the urgent need for adaptation strategies to address this looming crisis.

The Inevitability of Sea-Level Rise

The research, published in IOP Science, underscores that a global sea-level rise of two meters is inevitable, the timing of which depends on our greenhouse gas emissions and polar ice-sheet melting. Even with stabilized global temperatures, sea levels will continue to rise for centuries. This scenario isn’t just a distant possibility but a near certainty, with significant implications for coastal communities, ecosystems, and infrastructure.

After Europe’s recent extreme weather events, including the warmest summer on record and severe floods, it’s crucial that we take action on climate resilience. Adaptation actions not only contribute to recovery and resilience but also help mitigate climate change, protect biodiversity, ensure citizen safety, and secure financial stability.

The Inevitability of Sea-Level Rise

The research, published in IOP Science, underscores that a global sea-level rise of two meters is inevitable, the timing of which depends on our greenhouse gas emissions and polar ice-sheet melting. Even with stabilized global temperatures, sea levels will continue to rise for centuries. This scenario isn’t just a distant possibility but a near certainty, with significant implications for coastal communities, ecosystems, and infrastructure.

Why Immediate Action is Crucial

In response to the inevitable rise of sea levels, the study by Gonéri Le Cozannet et al. provides a comprehensive five-step approach to adapting our coastlines. Here’s how we can apply these strategies:

Adaptation Strategies for Coastal Areas

The study outlines several strategies:

  1. Prepare the Ground for Adaptation:
    • Raise awareness and improve climate literacy among communities and stakeholders.
    • Strengthen or create new governance institutions and mechanisms that prioritize coastal adaptation.
    • Engage with local communities to involve them directly in the adaptation process
  2. Assess Risks and Vulnerabilities:
    • Focus on long-lived assets and infrastructure that will be impacted by future sea-level rise.
    • Pay attention to vulnerable coastal communities, ecosystems, and habitats, encouraging a two-way exchange of ideas to identify risks and vulnerabilities.
  3. Assess Adaptation Options:
    • Identify all relevant adaptation options, including nature-based solutions and technological innovations.
    • Evaluate the feasibility, cost-effectiveness, and potential co-benefits of each adaptation option, as well as their limits.
  4. Implement Adaptation:
    • Prioritize options that offer high social, economic, and environmental co-benefits, and that align with sociocultural values and development priorities.
    • Aim to implement adaptation measures neither too late nor too early, leaving options open for future generations.
  5. Monitor Adaptation Progress:
    • Continuously monitor the implementation and effectiveness of adaptation strategies.
    • Assess early signs of sea-level acceleration and map adaptation plans and actions to respond promptly.
    • Progress an adaptive pathway to identify how current decisions contribute to long-term objectives, avoid future lock-ins, and maintain open options.

By following these strategic steps, we can establish climate services that support coastal adaptation to sea-level rise over decades to centuries. This iterative process requires us to think strategically about the different visions for coastal management areas and to act now for a resilient future.

The Role of Stakeholders

Coastal stakeholders, including governments, communities, and businesses, must acknowledge the reality of sea-level rise and act strategically. This includes planning for long-living infrastructure, adapting land-use decisions, and engaging in robust coastal zone management.

An authoritative, consistent and decision-oriented platform is still missing to meet the needs of adaptation practitioners concerned with the routine identification of coastal territories at risk from inundation, coastal land use planning, or maintaining coastal infrastructure services. 

Why do we need coastal risk assesment?

Even if climate change mitigation objectives agreed in Paris are met, sea level will rise at least by 0.3 to 0.6m in 2100 and then continue rising for centuries. The potential impacts of coastal flooding are a major source of concern for Europe because many infrastructures are located close to shorelines or in low-lying areas. Broad-scale coastal climate services and platforms available today have successfully addressed the need to raise awareness on mitigation.

However, an authoritative, consistent and decision-oriented platform is still missing to meet the needs of adaptation practitioners concerned with the routine identification of coastal territories at risk from inundation, coastal land use planning, or maintaining coastal infrastructure services.

What is CoCliCo Services?

The Coastal Climate Core Service (CoCliCo) project aims at informing decision-making on coastal risk and adaptation, by delivering an open web platform exploring dominant risk drivers, adjusting visualisation and analysis techniques to local decision contexts, and combining relevant and high-quality geospatial information layers. Through the platform, users will be able to visualize, download and analyse multiple decision-oriented coastal risk scenarios relevant to the rich user narratives of our Demonstration Case Studies address the three needs.

To meet this challenge, CoCliCo brings together European organizations and scholars that have proven track records of delivering broad-scale coastal risk and adaptation assessment, as well as leading research and technologies in interoperable geospatial data management, decision sciences, and risk communication.

This project created thanks to a funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 101003598.
