World Leaders Set to Address UN General Assembly Margaret Besheer UNITED NATIONS - World leaders involved in some of the most high profile geopolitical issues are among those set to speak on the first day of the U.N. General Assembly in New York. After opening remarks from U.N. Secretary-General Antonio Guterres, those gathered for the annual meeting will hear from a group that includes U.S. President Donald Trump, Turkish President Recep Tayyip Erdogan, Korean President Moon Jae-in and French President Emmanuel Macron. The addresses come a day after Swedish teen activist Greta Thunberg scolded world leaders at a U.N. summit calling for climate action, saying people are suffering and dying from the effects of global warming and that all the leaders have are empty words. "We are in [the] beginning of a mass extinction and all you can talk about is money," said Thunberg, who ignited a youth movement with her Friday school strikes for climate action. She said the science has been clear for 30 years, and still they are not doing enough. "You are failing us! But the young people are starting to understand your betrayal," Thunberg said in a voice filled with emotion. "The eyes of all future generations are upon you. And if you choose to fail us, I say we will never forgive you." The 16-year-old warned the more than 60 presidents and prime ministers gathered in the General Assembly hall for the summit that the youth would not let them "get away with this." She said they draw the line here and now and "change is coming," whether they like it or not. .
