Australian bushfires hit coal output, hazardous conditions to return

Mining giant BHP Group said on Tuesday that poor air quality caused by smoke from Australia’s bushfires is hurting coal production, as authorities said a reprieve from hazardous fire conditions would end within days.

The warning from the world’s biggest miner showed how an unusually long bushfire season that has scorched an area one-third the size of Germany is damaging the world’s No. 14 economy.
