In a world increasingly shaped by climate change, the rising tides are not just an environmental concern; they are a profound health crisis. Former UN climate chief Christiana Figueres has drawn attention to this urgent issue, emphasising that nations are being “held hostage” by their dependence on fossil fuels. As she takes on the role of co-chair for a new Lancet Commission, Figueres is determined to highlight the health implications of sea-level rise, particularly for vulnerable communities like those in the Pacific islands.
A Call to Action
The Lancet Commission, which will report its findings by September 2027, aims to explore how sea-level rise is transforming health, wellbeing, and social equity. With many Pacific nations, including Tuvalu and Kiribati, facing the potential of becoming uninhabitable in the coming decades, the urgency for worldwide action is palpable. Figueres stated that the commission would not only assess the immediate health impacts but also explore legal frameworks to hold those responsible for climate-related harms accountable.
The commission’s formation comes in the wake of growing calls from Pacific island health ministers, who have underscored the need for a global focus on sea-level rise as a critical health and justice issue. As rising seas contaminate drinking water and threaten food security, entire communities are being uprooted, leading to a crisis that extends well beyond environmental degradation.
The Human Cost of Climate Change
The implications of sea-level rise are stark. As waters encroach upon land, they bring with them salinisation that undermines agriculture and drinking water supplies. This, Figueres notes, is not merely an environmental issue but a matter of human dignity and survival. “It is affecting drinking water, sanitation, and food security,” she explained, highlighting the urgency of recognising the human toll of this crisis.
For many, the pain of displacement is a haunting reality. Figueres poignantly described the anguish of having to leave ancestral homes, saying, “Can you imagine the pain of having to leave the bones of ancestors?” This emotional burden cannot be quantified in economic terms; it resides in the grief and loss experienced by communities as they confront a future of uncertainty.
The commission will seek to address not only the current health impacts of climate change but also the intergenerational trauma inflicted on displaced populations. Young people in affected regions grow up with the stark understanding that their futures are compromised, often questioning whether they want to bring children into a world ravaged by climate upheaval.
Legal Accountability and Future Directions
The establishment of the Lancet Commission coincides with a landmark advisory opinion from the International Court of Justice (ICJ) in 2025, which asserted that countries have a legal obligation to prevent climate harm. While this opinion is non-binding, Figueres believes it will pave the way for increased climate litigation and hold polluters accountable for the damage inflicted upon nations that contribute the least to climate change.
However, challenges loom. Some states are reportedly attempting to block resolutions that would enforce accountability measures regarding climate harm, highlighting the complex interplay between politics and environmental justice. Figueres remains hopeful that a combination of legal pressure and scientific evidence will galvanise action, asserting that “enlightened self-interest” among governments and corporations could lead to significant emissions reductions.
The Path Forward
As the world grapples with the realities of rising sea levels, the need for a comprehensive approach to climate and health has never been more critical. Figueres urges both governments and businesses to reconsider their roles in this crisis, advocating for emissions reductions not just as a moral obligation, but as a necessity for economic stability and public health.
The commission’s work will be vital in framing these issues in human terms, connecting the dots between climate action and the wellbeing of communities globally. By focusing on health impacts, the commission aims to shift the narrative from abstract statistics to the lived experiences of those on the frontlines of climate change.
Why it Matters
The rising seas are not merely a distant threat; they are a pressing reality for many communities today. As health crises brought on by climate change continue to unfold, it is imperative that we acknowledge the profound injustices at play. The work of the Lancet Commission represents a crucial step towards holding those responsible accountable and ensuring that the voices of the most affected are heard. In doing so, we can begin to address the interconnected challenges of climate change, health, and social equity, paving the way for a more just and sustainable future.
