A fire broke out at COP30 in Belém, Brazil, forcing evacuations and disrupting United Nations climate talks at a critical time when negotiators were strenuously trying to reach an agreement on how to bolster climate efforts. The blaze erupted in the Blue Zone's pavilion space, where side events take place during official negotiations. It was brought under control within just minutes and everyone was evacuated safely, however officials temporarily closed the site for safety checks. "As a precaution, the Brazilian Government and the UNFCCC have jointly decided to temporarily close the Blue Zone while the fire department carries out a comprehensive safety assessment," the organisers wrote in a statement. The cause of the fire was believed to be an electrical device, likely a microwave, the local fire service said. 13 people were treated on site for smoke inhalation.

Some negotiators worry the delay in addition to the initial lack of agreement may force additional compromises. ''People tend to feel a little closer during an emergency like this, [...] but there are pretty deep fundamental interests at play," said veteran climate negotiations observer Alden Meyer of the European think-tank E3G, "you could get something that's so weak that no one wants it". Just a few hours before the fire, UN Secretary-General António Guterres had urged countries to "show willingness and flexibility to deliver results," which he said demands "compromise and common ground". On Wednesday, the summit had already missed a self-imposed deadline to reach an agreement on a few key issues, including on how to increase climate finance to developing countries and fossil fuel phaseout. Guterres, however, emphasised he is "perfectly convinced" that an agreement could be reached even on these contentious issues. He added that not adopting the strongest measures would be a failure.
