Life beneath waves in Northern California: Bridging global change and local action

“Coasts are where global change is made locally relevant, where people can really see their connection to the ocean.” Oxygen loss and acidification are impacting ecosystems and fisheries: addressing how climate change is reshaping life beneath waves is crucial to understanding the future of our coasts. Insights from CMCC Bassi Fellow Samantha Siedlecki on multi-decadal changes in coastal oceans and their implications for marine life and local communities.

COP30 | From the Mediterranean to the global ocean. Coppini (CMCC): “We build coastal resilience by developing solutions and anticipating future scenarios”

At COP30, the Mediterranean emerges as a laboratory for climate resilience – where environmental, social, and technological innovation converge. The region, deeply affected by the climate crisis, is also a space of connection: between continents, communities, and knowledge systems. As the European Commission advances the new Pact for the Mediterranean, aiming to create a more connected, prosperous, and resilient region, CMCC research and initiatives showcased at COP30 highlight how science, governance, and people-centred approaches can drive this transformation.

From forecast to action: The Mediterranean’s rising climate challenge

Home to over 500 million people across 22 countries whose lives are closely shaped by its waters, the Mediterranean Sea is not only a vital marine ecosystem but also one of the world’s most vulnerable climate hotspots, currently warming 20% faster than the global average. July 8th marks the International Day of the Mediterranean Sea — a moment to reflect on its importance and the urgent challenges it faces.

No adaptation without community engagement

The key takeaway from day two at ECCA2025 is simple: communities need to be involved in the entire adaptation process. Not just as recipients of information, but as active partners that help shape solutions. “This is all about people,” says Philippe Tulkens of the EU Mission on Adaptation to Climate Change. It’s not about top-down strategies, but about building trust, enabling dialogue, and overcoming barriers together. Engagement is a two-way process that involves listening, adapting, and co-creating. The second day of ECCA was rich with discussions on engagement, trust, and resilience.

Rising seas, rising challenges: Informing the future directions of coastal resilience

Sea-level rise will continue to threaten ecosystems and communities in the coming decades. However, the extent and magnitude of this threat is still an open question that researchers are intent on investigating in an effort to provide decision-makers with accurate and timely information. Giulia Galluccio, CMCC director of ATEC, vice-chair of JPI Climate and co-lead author of two chapters of the 1st European Assessment Report on Sea Level Rise, and CMCC researcher Elisa Fiorini Beckhauser walk us through the report, its significance and implications.

CoastPredict: Coastal science at the heart of global transformation

Oceans play a central role in the climate system and the way they interact with coastlines leads to both great opportunities and some of the most pressing hazards concerning climate scientists. “Rising sea levels, intensifying storms, marine pollution, and coastal erosion highlight the need to improve our understanding of coastal systems and our ability to manage risks effectively,” says CMCC Strategy Council member and co-chair of CoastPredict, Nadia Pinardi.

A climate compass: Advanced research directions to understand and design the future

The current effects of climate and the increasingly analytical understanding of what will happen in the future. Big data and the challenges of Machine Learning and Artificial Intelligence. Increasingly detailed and understandable climate data to better define policies and strategies for the interaction between human societies and nature. The European State of the Climate 2023 through the lens of CMCC’s research strategy in the words of Simona Masina, director of the Institute for Earth System Prediction, and Monia Santini, director of the Institute for Climate Resilience.

Navigating coastal dynamics and building resilience

Around 40% of the global population resides on coasts, with many relying on coastal resources for sustenance. Climate change exacerbates coastal hazards, compelling decision-makers and asset owners to address coastal resilience. Delphine Lobelle, Climate & Nature advisor at Fugro, highlights the importance of understanding coastal dynamics to empower stakeholders and promote proactive measures for coastal resilience.

Science and knowledge: The keys to a healthy Ocean Decade

As the global community grapples with the urgency of preserving one of the planet’s most vital resources, the Ocean Decade Conference is striving to put science at the center of the process. Has the latest conference in Barcelona shown how to deliver the science we need for the ocean we want?

Isole Marshall

“We will not go silently to our watery graves”: How to save a nation from drowning

The Marshall Islands, a nation of low-lying atolls threatened by rising sea levels, is facing an existential crisis. Yet, amidst this adversity, the Marshallese people are not only adapting to climate change but also charting a path for survival. Drawing inspiration from their rich maritime heritage, the Marshall Islands have developed a groundbreaking National Adaptation Plan for Survival (NAP). This plan, unveiled at COP28, outlines a comprehensive strategy for addressing the climate crisis over the next century.
