Faltering governments will be blamed for famine and conflict abroad, and face stagnation and inflation at home, says climate chief at start of Cop30

“Not one single nation among you can afford this, as climate disasters rip double digits off GDP,” he said. “To falter whilst megadroughts wreck national harvests, sending food prices soaring, makes zero sense economically and politically. To squabble while famines take hold, forcing millions to flee their homelands – this will never be forgotten as conflicts spread.”
