Climate Crisis Takes Centre Stage as World Leaders Urge Stronger UN Action

The 80th United Nations General Assembly ended on Monday with a mix of urgency, frustration and calls for a stronger and more representative global institution.

More than 150 leaders addressed the annual gathering, highlighting concerns over conflicts, climate change, geopolitical tensions and the concentration of decision-making power among a limited group of countries.

A prominent demand came from nations seeking greater representation in global institutions. African countries renewed their push for permanent representation on the UN Security Council, while vulnerable island states highlighted the need for greater international attention to the threats posed by climate change.

At the same time, several leaders questioned whether the United Nations is delivering on its core purpose.

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

The question reflected a broader concern running through the week’s speeches: governments continue to rely on the UN as a forum for diplomacy and cooperation, but many believe its existing structures are struggling to respond effectively to today’s crises.

The debate comes eight decades after the UN was established in the aftermath of World War II, with the aim of preventing another global conflict and creating a framework for international cooperation.

Today, however, the organisation faces a different but equally complex set of challenges, including armed conflicts, growing geopolitical rivalries, climate-related risks and demands to reform institutions that many countries consider outdated.

The General Assembly therefore served not only as a platform for governments to outline their priorities, but also as a forum for questioning how the UN can remain effective and representative in a rapidly changing world.
