LRising sea levels will trigger a “tide of misfortune” for hundreds of millions of coastal inhabitants, warned the UN Secretary-General on Wednesday, urging action against global warming to prevent this catastrophe.
“Our world is in perilous waters,” Antonio Guterres stated at a summit held at the United Nations headquarters in New York, focusing on the accelerating rise in sea levels.
Scientists report that since the early 20th century, sea levels have been rising faster than in any previous century in at least 3,000 years, with the rate of increase accelerating.
From 1901 to 2018, sea levels rose by approximately 20 cm, including about 8 cm from 1993 to 2018. The rate of increase has reached 0.48 cm per year over the last decade, primarily due to the melting of the Greenland and Antarctic ice sheets.
Consequently, “nearly 900 million people reside in low-lying coastal regions,” Antonio Guterres highlighted.
“For them, rising seas signify a tide of misfortune: more severe storm surges, coastal erosion and flooding, submerged communities, polluted freshwater, devastated crops, damaged infrastructure, destroyed biodiversity, and shattered economies—with sectors such as fisheries, agriculture, and tourism suffering the most from the impacts of these storms.”

“Rising seas will transform not only coastlines but also economies, politics, and security,” he cautioned.
“We cannot allow the hopes and dreams of billions to be dashed. We cannot permit the total destruction of countries and communities. It is time to take action and save ourselves.”
If the world doesn’t act decisively and immediately to reduce emissions, this will merely be the beginning.
“In a worst-case scenario, humanity could witness a sea level rise of several meters,” said Guterres.
In this context, he reiterated his persistent appeal to major emitters, especially the G20 nations, to adopt ambitious actions, transition away from fossil fuels, and significantly boost assistance to vulnerable countries preparing for this impending tide.
While some island nations may literally vanish from the map, he also emphasized the need to address the legal implications for a state that loses its land territory and its people.
A study cited by UN climate experts (IPCC) indicates that five countries (the Maldives, Tuvalu, the Marshall Islands, Nauru, and Kiribati) are at risk of becoming uninhabitable by 2100, potentially creating 600,000 stateless climate refugees.
Rising Sea Levels: A Tide of Misfortune for Coastal Residents
LRising sea levels will unleash a “tide of misfortune” for hundreds of millions of coastal residents, the UN Secretary-General warned on Wednesday, calling for action against global warming to avoid this disaster.
Understanding the Current State of Rising Sea Levels
“Our world is in dangerous waters,” Antonio Guterres stated at a summit at the United Nations headquarters in New York focused on accelerating sea level rise. Since the beginning of the 20th century, scientists report that sea levels have risen faster than in any century in at least 3,000 years, and this rate is continuing to increase.
Historical Data on Sea Level Rise
From 1901 to 2018, the global sea level rose by approximately 20 cm, which includes around 8 cm from 1993 to 2018 alone. Over the past decade, the rate of increase has reached 0.48 cm per year, primarily driven by the melting of the Greenland and Antarctic ice caps.
At-Risk Populations
Antonio Guterres emphasizes that nearly 900 million people live in low-lying coastal areas. For these populations, rising seas pose a severe threat:
- More intense storm surges
- Coastal erosion
- Flooding of communities
- Contamination of freshwater supplies
- Destruction of crops
- Damage to infrastructure
- Loss of biodiversity
- Economic challenges, impacting sectors like fisheries, agriculture, and tourism
The Broader Implications of Rising Sea Levels
“Rising seas will reshape not only coasts but also economies, politics, and security,” Guterres warns. It is crucial that we take action now to prevent a humanitarian crisis that endangers the hopes and aspirations of billions.
The Urgency of Action
In a worst-case scenario, Guterres cautions that humans today could witness a sea level rise of several meters. He reiterates the need for the G20 countries and top emitters to make substantial commitments to reduce greenhouse gas emissions and transition away from fossil fuels. Moreover, he highlights the necessity of increased aid to vulnerable countries to prepare for this imminent challenge.
The Uncertain Future of Island Nations
As some island nations face the possibility of disappearing entirely under rising sea levels, questions arise about the legal status of states without land — how will their residents be governed and supported?
Impending Climate Refugees
According to a study cited by UN climate experts (IPCC), five countries are at risk of becoming uninhabitable by 2100:
| Country | Estimated Climate Refugees |
|---|---|
| Maldives | Approximately 393,500 |
| Tuvalu | Approximately 11,500 |
| Marshall Islands | Approximately 58,000 |
| Nauru | Approximately 10,000 |
| Kiribati | Approximately 100,000 |
What Needs to Be Done?
Immediate and decisive action is crucial to mitigate these challenges. Here are some practical steps to consider:
1. Advocate for Policy Changes
Engage with community leaders and policymakers to encourage system changes that reduce fossil fuel consumption.
2. Support Legislation
Support local and national legislation that aims to combat climate change and protect vulnerable communities.
3. Raise Awareness
Educate others about the impacts of climate change, particularly sea level rise, and its socioeconomic effects.
4. Participate in Local Initiatives
Join local environmental groups or initiatives that focus on climate action and community resilience.
Conclusion
Addressing the issue of rising sea levels and its far-reaching consequences requires global solidarity, innovative thinking, and urgent action. By working together, we can mitigate the impact of climate change, protect vulnerable populations, and secure a sustainable future for generations to come.
