Climate change: An 'existential threat' to humanity, UN chief warns global summit

Deep global divisions and conflicts must end to clear a path to tackling world’s two existential threats: climate change and the negative impacts of the artificial intelligence (AI) boom, UN chief António Guterres told the Shanghai Cooperation Organization (SCO) Summit in Astana on Thursday.

There needs to be a major shift in global governance to better tackle such current and looming challenges as the climate crisis and rising security threats, according to a new UN report published on Tuesday.

Water scarcity and poor access to safe water sources pose major challenges for two-thirds of the world’s population, the United Nations food security agency said Tuesday, warning that worsening shortages could soon force people to leave their communities.
