The toll of Australia’s Black Summer of bushfires

Australia’s Summer of Crisis  was published by the Climate Council of Australia in March, describing the economic and climate change impacts of the bushfires of 2019/20. Although the bushfires were widespread, the report focuses on the two most severely affected areas of the country:  New South Wales and the Australian Capital Territory. It estimates that there was a 10-20 percent drop in international visitors, so that the tourism sector alone will lose at least $4.5 billion.  Bushfire-related insurance claims in New South Wales, Queensland, South Australia and Victoria totalled an estimated value of $1.9 billion.  The report also estimates the unprecedented climate impacts – between 650 million and 1.2 billion tonnes of carbon dioxide spewed into the atmosphere ( Australia’s annual emissions are around 531 million tonnes). The report states that the hot dry conditions which fuelled the fires will only worsen, and calls urgently for an end to fossil fuel production and export, and a plan to reduce Greenhouse Gas Emissions to net zero.

Health impacts

Unprecedented smoke‐related health burden associated with the 2019–20 bushfires in eastern Australia”, published in the Medical Journal of Australia (March 12) estimated that bushfire smoke was responsible for more deaths than the fires, and extraordinary health impacts. The researchers estimate there were  417 excess deaths, 1124 hospitalisations for cardiovascular problems and 2027 for respiratory problems, and 1305 presentations to emergency departments with asthma.  The article is summarized by The Guardian here  , which also reports that the authors have obtained funding for follow-up studies through the Centre for Air Pollution, Energy and Health Research (CAR), funded by Australia’s National Health and Medical Research Council .  The CAR website offers fact sheets and research summaries about bushfire impacts.
