PARIS, France (AFP) — United Nations (UN) chief Antonio Guterres challenged artificial intelligence (AI) firms on Tuesday to disclose their growing environmental footprint as part of a push for faster global action to curb climate change. As Europe bakes under a second heatwave in as many months, Guterres delivered a speech in London that painted a stark picture of a planet that has just endured its 11 hottest years on record. "Climate chaos is accelerating before our eyes," Guterres said, while the energy crisis, fuelled by war in the Middle East, is "exposing the folly of a world hooked on hydrocarbons".
