Nations urged to take 'great leaps' at United Nations climate talks

The UN climate conference, known as COP28, opens in Dubai with nations under pressure to address global warming, wean off fossil fuels, and make deeper cuts to emissions. The UAE, an oil-rich host, faces criticism for hosting the talks, especially after the appointment of Sultan Al Jaber, head of UAE oil giant ADNOC, as COP president. The conference aims to evaluate progress in curbing global warming and address thorny issues such as the future of fossil fuels and climate finance for poorer countries.
