But the ill-timed blackout fed an ­undercurrent of scepticism that this year's summit - dubbed "the indigenous peoples Cop" - will deliver on organisers' promise to put them front and centre at the event on the edge of the Amazon rainforest where many indigenous groups live. Indigenous peoples safeguard much of the world's biodiversity and are among those who contribute the least to climate change, yet they're disproportionately harmed by the devastation it causes.
Delegates from around the world are expected to disagree over how to tackle climate change and who should pay. The 30th annual United Nations climate change conference (COP30) begins on Monday in the Brazilian city of Belem. About 50,000 people from more than 190 countries, including diplomats and climate experts, are expected to attend the 11-day meeting in the Amazon. Delegates are expected to discuss the climate crisis and its devastating impacts, including the rising frequency of extreme weather.
