Now trending: Swedish activist Greta Thunburg’s fright upon seeing him. See for yourselves… Right there. There you have the moment. President Trump had announced he was skipping that summit, but made a sudden appearance at the hall where it was being held. The face of Greta Thunberg, one of the most prominent protagonists against climate change, says it all. Greta Thunberg’s speech at that summit is another one of today’s news stories. Such an impassioned speech is seldom heard at the U.N. Between tears and anger the activist accused world leaders of doing nothing in the face of the threat of mass extinction. Meanwhile, dozens of protesters were detained in the streets of Washington. Javier Vega reports.
