The UN climate summit in Belem, Brazil, has commenced without the participation of leaders from the world's three largest polluters: China, the United States, and India. This absence has raised significant concerns regarding the global commitment to tackling climate change. Brazilian President Luiz Inácio Lula da Silva highlighted the critical nature of the summit, stressing that the window for effective action is closing quickly. The gathering aims to convert prior commitments into tangible actions to reduce greenhouse gas emissions, protect rainforests, and fulfill pledges related to clean energy financing. The lack of attendance from key nations has led to criticism from various Latin American leaders and activists, who argue that it reflects a failure to prioritize climate action.
