PARIS (AP) — World leaders, heads of international organizations and activists are gathering in Paris for a two-day summit aimed at seeking better responses to tackle poverty and climate change issues by reshaping the global financial system. Developing nations point to an outdated system where the United States, Europe, China and other big economies that have caused most climate damage are leaving the poorest countries to deal with the consequences. The Paris talks also come as the COVID-19 pandemic, the war in Ukraine and a global debt crisis have led to a drop in life expectancy and an increase in poverty in most countries around the world, the United Nations Development Program reported.
