MADRID (AP) — Climate activist Greta Thunberg says that business and political leaders are misleading the public by holding negotiations that are not leading to real action against warming temperatures, which she referred to as a climate emergency. In a fact-filled speech at a plenary with negotiators from hundreds of countries in Madrid, she said that the United Nations climate talks had turned into opportunities to negotiate loopholes and avoid raising ambition. The activist said that pledges to reduce emissions were not enough and that carbon needs to remain underground and greenhouse gases responsible for rising temperatures need to be zeroed.
