Greta Thunberg and UN Secretary-General Antonio Guterres blasted fossil fuel companies for "killing our planet" at the COP31 talks in Turkey, where Thunberg — attending her first summit since 2021 — called the annual conference hypocritical and "full of lobbyists." Guterres urged governments to tax oil companies' windfall profits, while the negotiations, running to 20 November, face low expectations of breakthroughs amid the US war with Iran and Russia's war in Ukraine.
