Living on a tropical island can be a real treat, especially when you don't have to worry about drought: the climate is mild all year round, there are beaches teeming with life, jungles with a multitude of plants and animals unique in the world… However, due to climate change, it can also be dangerous.
Vanuatu is a Melanesian archipelago facing severe threats from climate change. Sea levels are rising faster there than anywhere else in the world, averaging 6 millimeters per year since 1993 (a total of 11 centimeters), while in other regions the average is between 2,8 and 3,6 mm annually. This phenomenon seriously jeopardizes the existence of this magnificent South Pacific nation. To learn more about the effects of climate change on different regions, see the article on the vulnerability of the Mediterranean to climate change.
As reported by Greenpeace , actor and model Jon Kortajarena has participated in expeditions to Vanuatu to understand firsthand what it's like to live there, visiting communities that have been displaced due to rising sea levels. Currently, 100,000 people are at risk from this phenomenon . This situation is a clear example of how climate change affects vulnerable communities, as discussed in the analysis of children affected by climate change.

However, rising sea levels are not the only problem Vanuatu faces. Tropical storms are another significant threat, affecting approximately 30,000 people annually . This means that nearly half of Vanuatu's population is exposed to natural disasters each year, which is closely linked to the cities that could disappear due to global warming. To better understand the disasters that can occur in vulnerable regions, you can read about the worst natural disasters of 2016.
Greenpeace spokesperson Pilar Marcos stated that "this is not about being alarmist, but scientists warn that time is running out: if appropriate measures are not taken before 2020, it will become increasingly difficult to prevent the planet's temperature from rising above 1,5ºC . This is the threshold beyond which the worst phenomena caused by climate change are likely to occur."
In the energy sector, it has been observed that in 2011, 34% of Vanuatu's energy demand came from renewable sources , and this figure is expected to reach 100% by 2030. This raises a troubling question: does humanity truly only commit effectively when directly confronted with a problem? If this trend continues, it will be difficult for planet Earth to remain so beautiful for future generations. Climate change is a challenge that many nations must face, as highlighted in the analysis of the need for technology for farmers in the face of climate change.
The current situation in Vanuatu and its international response
The situation in Vanuatu has led to intense international mobilization. The country has become a symbol of the fight against climate change, not only because of its vulnerability, but also because of its role in international climate diplomacy. In this context, Vanuatu has launched an initiative before the International Court of Justice (ICJ) to have states' obligations regarding global warming recognized.
The International Court of Justice (ICJ) has been called upon to clarify countries' responsibilities regarding climate change and the consequences faced by those who fail to meet their obligations. This request was supported by the organization Pacific Island Students Fighting Climate Change , which emphasizes the urgency of addressing the climate crisis, especially for small island developing states—an issue closely linked to the potential disappearance of cities due to global warming.
On March 29, 2023, the UN General Assembly adopted resolution A/RES/77/276, supported by 132 countries, requesting an advisory opinion from the ICJ on the obligation of States to protect the environment and human rights in the face of climate change. This resolution is crucial, as it is based on fundamental principles of international law. Vanuatu's voice stands as a strong reminder of international justice in matters of climate change.
The ICJ hearings, held from December 2 to 13, 2024, were a historic event. With the participation of 97 States and 11 international organizations, this is considered the largest submission ever made before an international court. The hearings focused on two key questions: What are States' obligations to protect the climate system for present and future generations? And what legal consequences do States face whose actions or omissions have caused significant damage to the climate system?
The threats faced by Vanuatu
Vanuatu experiences extreme weather events more frequently than most countries. Ocean acidification, rising sea temperatures, and changing rainfall patterns are leading to a natural resource crisis. For example, freshwater sources are becoming increasingly scarce, and water salinization is a growing problem. This is impacting crops and fisheries, posing a direct threat to the food security of local communities. It is alarming how climate change is affecting not only Vanuatu but also other ecosystems, as discussed in the article on plant adaptation to climate change , which is also a challenge for Vanuatu.
Furthermore, rising sea levels and coastal erosion are forcing many coastal communities to abandon their homes. Some residents have already had to migrate to other islands or even other countries, jeopardizing their culture and traditions. Vanuatu's situation serves as an example of how climate change can lead to forced migration, a phenomenon with global repercussions that affects many nations, as discussed in analyses of the differences between climate change and global warming.
For some years now, relocation plans have begun to be implemented, but experience on the ground suggests that these decisions are not easy to carry out. Communities face emotional, cultural, and logistical challenges, which complicate the process of adapting to climate change. In this context, it is relevant to consider how climate change affects the health of pregnant women, as discussed in the article on the effects on pregnant women.
Future prospects for Vanuatu
Vanuatu's future depends largely on international action against climate change. Although the country is one of the smallest emitters of greenhouse gases, its situation illustrates the global injustice of climate change: the countries that contribute the least to global warming are the ones that suffer its effects the most . This reflects a critique of the international system that must be addressed urgently.
Initiatives like the one Vanuatu brought before the ICJ could set a precedent in international law, establishing a framework that compels major emitters to take responsibility. This is essential not only for Vanuatu, but for all small island states facing the devastating effects of climate change. It is crucial that the world becomes aware of how global warming is impacting natural resources, as can be seen in the analysis of deserts threatened by global warming.
Mobility and the shift towards a more sustainable economy are central to Vanuatu's agenda. For example, its national development plan focuses on improving climate resilience, reducing dependence on fossil fuels, and increasing investment in renewable energy sources. To learn more about the challenges it faces, it is relevant to examine how cities like Miami could be affected, as discussed in the article on flood risks in Miami.

Furthermore, adaptation strategies are being implemented that involve local communities in decision-making. These initiatives are vital to ensuring that residents' voices are heard and that solutions are tailored to their needs. Adaptation is fundamental to mitigating the effects of climate change, as described in the article on investment in green infrastructure.
However, this will not be enough without a firm commitment from the international community. Failure to act on the part of major emitting countries could mean the demise of entire nations, as has been seen in the case of Vanuatu and other Pacific island states.
Vanuatu's struggle is a reminder that climate change is a human rights issue. Vulnerable communities have the right to live in a healthy environment and enjoy the resources they need to thrive. International pressure on major powers must increase, and climate justice must become a fundamental pillar of global governance.

The situation in Vanuatu highlights one of the most important struggles of the 21st century. The combination of climate vulnerability and the fight for global justice is a challenge that must be urgently addressed. Decisions made today will influence the lives of millions in the future.
