Presidents and prime ministers from 200 nations have arrived in the city of Glasgow in Scotland for the 26th UN Climate Change Conference – COP26. One notable person is missing. Swedish climate activist Greta Thunberg has been omitted from the invitation list. Ms Thunberg, 18, is unsure as to whether she will be allowed to attend any of the meetings. Speaking to the BBC, she said: "It's very unclear. Not officially [invited]." She added: "I think that many people might be scared that if they invite too many radical young people, then that might make them look bad."

U.S. President Joe Biden will be at the event. He was in Rome on Friday for a meeting with the Pope. Climate activists found his 95-car motorcade a little ironic, just two days ahead of a climate conference. Ms Thunberg criticised the conference for its lack of delegates from developing countries. She said: "We need more representation from the Global South." The UK's Prime Minister Boris Johnson is hosting the conference. He said: "COP26 must mark the beginning of the end of climate change." He added: "Too many countries are still doing too little."
