A top UN climate official demanded Brazilian authorities immediately develop a plan for addressing security lapses, soaring temperatures, flooding and other poor conditions at the COP30 conference in the city of Belém.

Simon Stiell, executive secretary of the UN Framework Convention on Climate Change, rapped Brazilian authorities for a security breach Tuesday night, when activists stormed into the conference venue, and said officers had failed to disperse other protesters Wednesday morning inside a security zone where such civil actions are forbidden.
