The United Nations has warned that climate-related disasters and conflict have displaced millions of people across the globe,

The UN’s High Commissioner for Refugees (UNHCR) noted in a report, published today to coincide with the launch of the 30th annual UN Climate Change conference (COP) in Brazil, that weather-related disasters caused about 250 million people to flee their homes over the past decade.

The migration agency issued its second major report on the effect of climate change on refugees – No Escape II: The Way Forward – in the run-up to COP 30, as it appears that the enthusiasm of countries to agree action to curb climate change continues to diminish.

According to the report, weather-related disasters have caused some 250 million internal displacements over the past decade – equivalent to over 67,000 displacements per day.

The UNHCR added that climate change is also increasing the difficulties faced by those displaced by conflict and other driving forces.

It emphasized that climate change is “compounding and multiplying the challenges faced by those who have already been displaced, as well as their hosts, particularly in fragile and conflict-affected settings.”

Floods in South Sudan and Brazil, record heat in Kenya and Pakistan, and water shortages in Chad and Ethiopia are among the disasters noted in the report.

The number of countries facing extreme exposure to climate-related hazards is projected to rise from three to 65 by 2040. Those 65 countries host more than 45 percent of all people currently displaced by conflict, it added.

UN Refugees Chief, Filippo Grandi said in a statement that extreme weather is “… destroying homes and livelihoods, and forcing families – many who have already fled violence – to flee once more.”

“These are people who have already endured immense loss, and now they face the same hardships and devastation again. They are among the hardest hit by severe droughts, deadly floods and record-breaking heatwaves, yet they have the fewest resources to recover.”

By 2050, the report said, the hottest 15 refugee camps in the world – in The Gambia, Eritrea, Ethiopia, Senegal and Mali – are projected to experience nearly 200 days of hazardous heat stress per year.

The refugee agency’s report emphasised that while the effect of climate change is growing, the commitment towards dealing with it has been weakening.

The UNHCR hopes to reawaken efforts to fight the effects at the conference in Brazil.

Under President Donald Trump, the United States, traditionally the world’s top donor, has slashed foreign aid. Washington previously accounted for more than 40 percent of the UNHCR’s budget. Other major donor countries have also been tightening their belts.

UN Bemoans Funding Cuts Effect On Combating Climate Change

Grandi said that funding cuts are severely limiting “our ability to protect refugees and displaced families from the effects of extreme weather.”

“To prevent further displacement, climate financing needs to reach the communities already living on the edge,” he said. “This COP must deliver real action, not empty promises.”

About 50,000 participants from more than 190 countries will meet in Belem, in the Amazon rainforest, to discuss curbing the climate crisis.

One topic on the agenda exposing the difficulties of agreeing on global action is the European Union’s Carbon Border Adjustment Mechanism (CBAM).

The policy is designed to prevent “carbon leakage” by requiring importers of carbon-intensive goods like steel and cement to pay the same price for embedded emissions that EU producers face domestically.

While the EU promotes CBAM as a necessary environmental tool to encourage greener practices, critics of the policy, including major trading partners like the US and China, view it as a veiled act of protectionism.

Developing nations, meanwhile, are concerned that it unfairly shifts the financial burden of climate action onto them.
