Climate Change Threat Grows as World Leaders Call for Greater UN Action

Doom, distrust and frustration dominated this year’s United Nations General Assembly, with world leaders calling for greater representation, stronger cooperation and a more effective global institution.

The weeklong gathering, which concluded on Monday, brought together more than 150 leaders who used their speeches to highlight concerns ranging from climate change and unequal power structures to political and military coercion.

A recurring demand came from countries seeking a greater voice in global decision-making. Small island nations facing the growing impact of climate change called for stronger representation, while African countries renewed calls for permanent seats on the UN Security Council.

But beneath these demands was a broader concern: whether the United Nations remains capable of addressing the world’s biggest crises.

“Where are the United Nations?” El Salvador’s Foreign Minister Alexandra Hill Tinoco asked on Monday. “Do we have an organisation that is still relevant?”

Her questions reflected a sentiment repeated in different forms throughout the General Assembly. Many leaders said they wanted the UN to remain an effective forum for international cooperation, while also expressing frustration over its inability to prevent or resolve major conflicts.

The debate comes as the United Nations approaches its 80th anniversary. The organisation was established after World War II with the goal of preventing another global conflict and providing a framework for countries to work together.

This year’s General Assembly, however, was marked by repeated questions about whether that framework is keeping pace with a world facing wars, geopolitical rivalries, climate-related threats and demands for a more representative international system.

Across more than 150 speeches, the message was clear: governments continue to see value in the UN, but many believe its institutions need to become more representative and more effective if it is to meet the challenges confronting the world.
