Digest

This podcast introduces a landmark Lancet Commission report on sea level rise, health, and justice, highlighting its profound impacts on vulnerable communities. It features interviews with commissioners who discuss the urgency of addressing sea level rise not just as a climate issue but as a current health crisis. Personal accounts from Pacific Island communities and Indigenous Australians reveal devastating consequences, including physical injuries, diseases from saltwater intrusion, food insecurity, mental health deterioration, and the loss of cultural identity and spiritual connection to land. The report emphasizes the need to reframe sea level rise as a health emergency, advocating for collective action, indigenous wisdom, and a focus on climate justice to humanize the climate change discussion and inspire radical hope for solutions.

Climate Justice


Addressing the disproportionate burden of climate change impacts on vulnerable populations and advocating for equitable solutions and support.

Saltwater Intrusion


The contamination of freshwater sources by rising sea levels, leading to health problems, agricultural damage, and ecosystem disruption.

Food Insecurity


The threat to reliable access to food due to crop damage, land loss, and disrupted fisheries caused by sea level rise and extreme weather.

Mental Health Impacts


The psychological toll of climate change, including anxiety, depression, and trauma resulting from displacement, loss of home, and cultural disruption.

Indigenous Wisdom


Traditional knowledge and practices of indigenous peoples, offering valuable insights into environmental stewardship and resilience in the face of climate change.

Radical Hope

Q&A

  • How is sea level rise a health issue?

    Sea level rise directly impacts physical health through injuries and diseases from extreme weather and saltwater intrusion, damages health infrastructure, causes food insecurity, and leads to significant mental health issues due to displacement and loss of identity.

  • What are the primary impacts of sea level rise on Pacific Island communities?

    Pacific Island communities face direct health risks from flooding, saltwater intrusion contaminating freshwater and soil, leading to diseases and crop failure, resulting in food insecurity, malnutrition, and severe mental health impacts from displacement and loss of ancestral lands.

  • How does sea level rise affect Indigenous Australians?

    Sea level rise disrupts Indigenous Australian economies tied to the land, alters crucial seasonal calendars, impacts deep spiritual connections to place and water, and causes distress when natural systems are stressed, affecting their ability to sustain communities.

  • What is the role of the WHO in addressing sea level rise and health?

    The WHO convened the Lancet Commission on Sea Level Rise, Health, and Justice in response to urgent requests from Pacific Island health ministers, recognizing sea level rise as an under-recognized public health crisis requiring global attention.

  • What does "radical hope" mean in the context of climate change?

    Radical hope is an active commitment to finding solutions, acknowledging the severity of the climate crisis while believing in humanity's capacity to address it through collective wisdom, collaboration, and determined action.

  • Why is it important to reframe sea level rise as a human issue rather than just a technical one?

    Reframing sea level rise as a human issue focuses on the tangible impacts on people's bodies, minds, livelihoods, cultures, safety, and dignity, making the crisis more relatable, urgent, and fostering greater empathy and a stronger call for action.

Show Notes

Sea-level rise is often spoken about in centimetres, forecasts and future scenarios. But what if we understood it as a health emergency that is already reshaping lives, harming bodies and minds, and displacing entire communities?


This week, as a landmark Lancet Commission launches, Christiana Figueres and Tom Rivett-Carnac argue that sea-level rise must be understood not just as a climate threat, but as a health crisis currently unfolding. And, as co-chair of the Lancet Commission on Sea-Level Rise, Health and Justice, Christiana brings us inside the thinking behind this urgent new effort.


Christiana speaks to commissioners ‘Ofa Kaisamy, Professor Anne Poelina and Dr Sandro Demaio, who paint a vivid picture of what happens before and as the water arrives. This is a story of food insecurity, damaged clinics and hospitals, disease, displacement, trauma, and the loss of ancestral knowledge and cultural continuity. But it also points to an opportunity to finally see sea-level rise in fully human terms, with those on the frontlines shaping the response.


What changes when we stop treating rising seas as a distant environmental problem and start recognising them as a present health emergency? And what might become possible if the people most affected are no longer treated as victims, but as leaders?
