UN Warns 90 Million Displaced People Face Climate Danger Before COP31

The climate crisis is tightening its grip on people already driven from home by war and persecution. A new United Nations assessment says nearly 90 million forcibly displaced people now live in countries highly exposed to drought, floods and extreme heat, placing survival itself at the center of the COP31 negotiations.

The UN refugee agency released the warning on November 6, three days before governments gather in Antalya, Türkiye. Nearly three quarters of the world's forcibly displaced population live in countries facing severe climate hazards. The figure does not describe a distant forecast. It maps danger around people already living with damaged infrastructure, insecure shelter and shrinking public services.

“Climate adaptation in fragile and displacement-affected areas is a matter of survival,” said Anton Leis Garcia, head of UNHCR's climate team. That blunt judgment cuts through the diplomatic language surrounding annual climate summits. A flood in a wealthy state can destroy property; the same flood in a refugee settlement can erase the last barrier between a family and catastrophe.

Yet finance flows in the opposite direction from need. UNHCR says only about 10 percent of international climate finance reaches fragile or conflict-affected countries. Wealthy governments are also falling far short of an estimated $305 billion in annual adaptation needs. The gap leaves host communities and displaced families paying for a crisis they did little to create.

Climate disruption does not replace war, persecution or political violence as the cause of forced displacement. It multiplies those pressures. It wrecks crops, contaminates water, intensifies competition over land and makes return unsafe. In the first half of 2026, more than two thirds of refugee returns went to countries already exposed to severe climate hazards.

Syria shows what that collision looks like. Nearly four million people have returned as conditions shift after years of conflict, but declining groundwater, erratic rainfall and flooding along the Euphrates threaten communities trying to rebuild. A return counted in migration statistics is not durable if a family cannot find drinking water, irrigate land or keep a home above floodwater.

Heat poses another slow-moving emergency. UNHCR projects that by 2050, one in three refugee settlements in sub-Saharan Africa could endure at least 100 days of dangerous heat each year. Some settlements in Ethiopia may face more than 200 such days. Those conditions threaten children, older people and workers while making clinics, schools and food storage harder to operate.

The immediate outlook is also volatile. A strong El Niño could bring severe floods across Somalia, Kenya, South Sudan and Uganda and displace as many as three million people by the end of 2026. That is a forecast, not a confirmed toll, but governments have little excuse to treat it as a surprise. Early warning without early finance simply records disaster in advance.

COP31 will test whether states treat adaptation as a frontline obligation or another negotiable promise. Funding must reach refugee-hosting countries before disasters strike, and it must reach local authorities and displaced communities directly. Water systems, heat-resistant shelters, drainage, reliable electricity and climate-resilient livelihoods are not abstract climate projects. They are the material foundations of safety.

Most refugees remain in low- and middle-income countries, which already carry the largest share of protection costs. Asking those states to absorb escalating climate shocks while richer governments with greater historical emissions restrict finance deepens an old imbalance. Climate policy that excludes people displaced by conflict reproduces the inequality that made them vulnerable.

The 90 million figure should force a sharper debate in Antalya. Governments cannot claim progress while money bypasses the places where climate danger and political violence converge. For displaced people, adaptation is not charity and not a public-relations add-on. It is protection, reconstruction and a measure of whether international solidarity means anything under pressure.
