Periodic Reporting for period 3 - CoCliCo (COASTAL CLIMATE CORE SERVICES)
Okres sprawozdawczy: 2024-03-01 do 2025-08-31
Sea-level rise is a highly specific adaptation challenge: unlike temperatures and precipitation, sea levels will not cease rising once climate change has been stabilized at a specific global warming level l (e.g. 1.5°C or 2°C, as per the Paris Agreement). On the contrary, they will continue to rise for centuries. By mitigating climate change, we can stabilise sea-level rise rates, but not sea levels themselves. Consequently, adaptation to coastal flooding and erosion will be continuously ongoing for decades and centuries. However, broad-scale climate and decision-oriented services to address this need are lacking in Europe, as in other regions of the word. CoCliCo contributes to filling this gap by developing a European climate service for adaptation to future flooding in the context of sea-level rise.
Why is the problem important to society?
The latest IPCC report has reminded us that the costs of sea-level rise impacts in Europe are projected to increase by a factor of at least 10 during the 21st century. The literature published so far suggests that protection is cost-efficient along most urbanized coasts. However, for many rural low-lying coastal areas, a choice will need to be made between protection and some relocation associated with the restoration of coastal ecosystems. Such choices have long-term social legacies, and whatever the final choice made, there will be a need for climate services to inform decision-makers about the consequences of their choices in terms of costs, people exposed, and other potential co-benefits and trade-offs (see Policy Brief produced during the 1st review period).
Overall project objectives:
The objective of CoCliCo is to improve decision making on coastal risk management and adaptation by establishing an integrated core service dedicated to coastal adaptation to sea-level rise.
The main deliverable will be an open source platform informing users on present-days and future coastal risks.
CoCliCo is organised around three pillars: user interactions (WP1), platform design (WP2) and production of new data allowing to assess coastal flood risks (WP3-6).
The project was disseminated extensively, with e.g. 37 presentations in conferences and high level meetings, public webinars, and outreach through ICLEI and partner networks. The integration within the European Digital Twin of the Ocean (EDITO), developed by Mercator Ocean, is ongoing, as planned in the Exploitation plan. A simplified CoCliCo-based demonstrator was showcased at the UN Ocean Conference (2025) to illustrate its policy relevance. From the launch in May 2025 to the end of the project in August 2025, the platform was visited from the with over 2,000 users and 16,000 interactions were recorded.
The activities of CoCliCo are implemented in the view of achieving the following impacts:
- Enhanced adaptive capacity
- Reduced vulnerability to climate change
- Enhanced action on adaptation
- Strengthened scientific knowledge on climate
- Better informed climate services and decision-making
The expected environmental and societal impacts of CoCliCo relate to:
o Sustainable Development Goals: SDG-9, SDG-11, SDG-13
o Adaptation objectives of the Paris Agreement,
o Sendai Framework for Disaster Risk Reduction,
o European Green Deal and the European Adaptation Strategy.
At this stage of the project, the environmental and societal impact is limited to raising awareness across users.
