"Surging Seas Are Coming For Us All"—UN Chief Warns About Rising Seas
It could happen much sooner than expected.
The United Nations Secretary-General Antonio Guterres has issued an urgent plea for global action to combat a “worldwide catastrophe” threatening Pacific Islands due to rapidly rising sea levels.
Speaking from Tonga during the Pacific Islands Forum, Guterres called for a dramatic increase in financial support and aid for nations most vulnerable to the climate crisis.
He emphasized that immediate action is needed "before it is too late" to address the unprecedented impacts of sea-level rise, which he described as “a crisis entirely of humanity’s making.”
Guterres' plea comes amid alarming new reports highlighting the dire state of the world’s oceans, particularly in the Pacific. According to the World Meteorological Organization’s (WMO) latest findings, sea surface temperatures in the Southwest Pacific have increased three times faster than the global average since 1980.
Even more concerning, sea levels in this region have risen at nearly twice the global rate over the past 30 years. This rapid rise has been fueled by ocean heating, a consequence of global warming driven by the burning of fossil fuels.
The reports paint a grim picture of the future for Pacific Islands, which are experiencing a "triple whammy" of ocean heating, sea-level rise, and acidification. These changes are already having devastating effects, damaging ecosystems, crops, and freshwater sources, while destroying livelihoods and causing loss of life.
In 2023 alone, the region experienced 34 storm and flood-related events, resulting in over 200 deaths and affecting 25 million people.
The WMO’s Secretary-General, Celeste Saulo, warned that the ocean is undergoing changes that will be "irreversible for centuries to come."
As human activities continue to drive up global temperatures, the ocean's ability to support and protect life is diminishing, turning a once-dependable resource into a growing threat.
A second UN report released Tuesday reinforces these concerns, stating that climate change and rising sea levels are no longer distant threats but immediate dangers, especially for the Pacific. The report emphasizes that the Pacific Islands, despite contributing just 0.02% of global emissions, are uniquely exposed to the impacts of rising seas due to their low-lying geography and proximity to the coast.

With an average elevation of just 1 to 2 meters above sea level, Pacific Islands face the prospect of even greater sea-level rise and more frequent flooding if global temperatures continue to climb.
The report projects that, at the current rate of warming, sea levels could rise another 15 centimeters by 2050, with coastal flooding becoming a regular occurrence.
The Intergovernmental Panel on Climate Change has already concluded that human activity is unequivocally responsible for the climate crisis, and recent research on climate tipping points and ice-sheet dynamics suggests that future sea-level and continent rise could be far more dramatic and occur much sooner than previously anticipated.

While the Pacific Islands are on the frontline of this crisis, Guterres stressed that rising sea levels pose a global threat, endangering low-lying islands, populous coastal cities, large tropical agricultural deltas, and Arctic communities.
Both UN reports urge global leaders to act swiftly to enhance early warning systems, significantly boost funding for climate resilience and adaptation, and make rapid cuts in greenhouse gas emissions to limit global warming to 1.5 degrees Celsius — a critical threshold agreed upon by world leaders to avoid catastrophic climate impacts.

“The ocean is overflowing,” Guterres warned. “Surging seas are coming for us all. The world must look to the Pacific and listen to science… if we save the Pacific, we also save ourselves.”
The message from Tonga is clear: the time for action is now. Without immediate and substantial efforts to reduce emissions and support vulnerable communities, the world risks losing entire nations to the sea.
The Pacific Islands may be the first to face this threat, but without urgent global action, they will not be the last.
