Climate Disasters Displace Millions as Haiti Faces Rising Risks
Over the past decade, climate-related disasters have uprooted an astonishing 250 million people worldwide, according to a recent UN report. That’s roughly 70,000 people forced to leave their homes every single day. This staggering number includes people who have been displaced more than once, highlighting just how relentless the combination of extreme weather and human vulnerability has become. Floods, storms, droughts, and extreme heat are not only wreaking havoc on communities but are also fueling conflict and food insecurity in already fragile regions.
In Haiti, one of the countries most exposed to climate hazards, the situation is particularly severe. The UNHCR describes the climate crisis as a “risk multiplier,” amplifying existing inequalities, violence, and displacement. While Haiti contributes minimally to global greenhouse gas emissions, its population faces repeated displacement, increasingly harsh living conditions, and limited access to resources. Across the world, fragile and conflict-affected nations like Haiti, Sudan, Syria, and Yemen are disproportionately bearing the brunt of climate disasters, yet they receive only a fraction of the support needed to adapt and protect vulnerable populations.

Tragic examples abound. In 2024, catastrophic flooding in Brazil’s Rio Grande do Sul state displaced 580,000 people, including tens of thousands of refugees from Haiti, Venezuela, and Cuba. A year earlier, Cyclone Mocha struck Myanmar, devastating Rohingya refugee camps already struggling with overcrowding and poverty. These disasters show a pattern that is all too familiar: those who have the fewest resources, yet contribute least to climate change, are the hardest hit.
Today, three-quarters of refugees live in countries facing high or extreme exposure to climate hazards. In Chad, for instance, floods forced more than 1.3 million people to flee in 2024 alone—more than the total displacement over the previous 15 years combined. Refugees from Sudan and other conflict-affected areas often receive less than ten liters of water per day, far below emergency standards. UNHCR warns that, by 2050, the hottest refugee camps could face nearly 200 days of dangerous heat annually, making many settlements uninhabitable and posing severe risks to health and survival.
Filippo Grandi, the UN High Commissioner for Refugees, has emphasized that funding cuts are severely limiting the ability to protect displaced communities from the effects of extreme weather. “To prevent further displacement, climate financing needs to reach the communities already living on the edge. They cannot be left alone,” he said, urging world leaders at COP30 in Brazil to take real, tangible action.
Without urgent global intervention, the report warns, Haiti and other vulnerable nations will continue to experience repeated displacement, deteriorating living conditions, and increased human suffering. The UN’s findings are a stark reminder that the climate crisis is not just an environmental issue—it is a humanitarian emergency demanding immediate and sustained action.
