Australia's biggest city is facing a "public health emergency" over the bushfire smoke that has choked Sydney for weeks, leading doctors warned Monday after hospitals reported a dramatic spike in casualty department visits.
Hundreds of climate change-fuelled bushfires have been raging across Australia for months, with efforts to contain a "mega-blaze" burning north of Sydney destroying an estimated 20 homes overnight and fires near Perth threatening towns.
More than 20 medical groups including the Royal Australasian College of Physicians -- which represents 25,000 doctors and trainees -- released a joint statement Monday calling on Australia's government to address the toxic air pollution.
"The air pollution in NSW is a public health emergency," the Climate and Health Alliance said.
"Smoke from bushfires has produced air pollution of up to 11 times the base 'hazardous' level in parts of Sydney and New South Wales.
"Bushfire smoke is particularly hazardous because of the high levels of tiny particles (PM2.5)."
"Our governments must act quickly to rapidly and deeply reduce greenhouse gas emissions, which we know are driving climate change."
