UN leaders gather as wars, AI risks, and climate crises dominate agenda

World leaders are gathering at the United Nations General Assembly this week amid major wars, political divisions, and growing concerns over unchecked artificial intelligence, climate shocks, and economic instability. The annual meeting comes as the UN faces questions about its effectiveness in resolving global conflicts. Around 130 heads of state are expected to speak, including US President Donald Trump and French President Emmanuel Macron. Key topics include wars in Ukraine, Gaza, and Sudan, UN Security Council reform, and the future of AI governance. Several major leaders, including China's Xi Jinping and Russia's Vladimir Putin, are skipping the event. The UN has faced a difficult year, including financial troubles and criticism over its limited role in peace and security. The US recently paid $725 million in dues, avoiding a loss of voting rights. UN Secretary-General Antonio Guterres, whose term ends in December, will deliver his final opening address, warning of an era of deep uncertainty.
