One of them was the largest recorded forest fire in Australian history. The fires in Australia have been burning for months, consuming nearly 18 million acres of land, causing thousands to evacuate and killing potentially millions of animals. A viewpoint published in the journal JAMA Internal Medicine February 28, 2020, discusses the lessons learned from the recent Australian bushfires in regards to climate change and public health.. Scientists agree that climate change is the reason for the dry and hot conditions that brought about the horrifying bushfires in Australia over the end of 2019 and the beginning of 2020. These Devastating Photos Show The Effects Of The Massive Bushfires In Australia Three people have died and more than 100 homes destroyed as bushfires continue to rage in Australia. These will increase Australia’s annual greenhouse gas emissions, contributing to global warming, and heighten the likelihood of recurring megafires that will release yet more emissions. The effects of smoke exposure and inhalation range from eye and respiratory tract irritation to more serious disorders, including reduced lung function, bronchitis, exacerbated asthma and premature death. Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. Bushfires are generally slower moving, but have a higher heat output. Physical, direct impacts. Such experiences can have lasting mental health impacts across affected communities.

Smoke from the 2019-2020 Australian bushfires is seen from space drifting across the Pacific Ocean. Source: NASA. Photos of singed koala feet and charred noses are perhaps the most heartbreaking. It is often pushed into the stratosphere by the heat from fires. These areas include Australia. Significant local infrastructure has also been destroyed, including roads, energy, telecommunications and community assets. In addition to human fatalities, many millions of animals are reported to have been killed. 38; Media Ltd. Publishing Services by Elsevier B.V. on behalf of KeAi Communications Co. Ltd. https://doi.org/10.1016/j.jnlssr.2020.06.009. australia’s emissions sky rocketed The bushfires are estimated to have released between 650 million and 1.2 billion tonnes of carbon dioxide into the atmosphere. By March 2020 Black Summer fires burnt almost 19 million hectares, destroyed over 3,000 houses, and killed 33 people. Faster-melting glaciers. Gabriel H. Sanchez BuzzFeed News Photo Essay Editor Posted on November 12, 2019, at 4:55 p.m. They have a low to medium intensity and primarily damage crops, livestock and farming infrastructure, such as fences. With the effects of climate change and environmental degradation showing up the world over, the bushfires are acting as more fuel. Data showed that they were unprecedented in terms of impact on all areas. The total cost of the fires, including the cost of suppression measures and lost productivity, would be much greater than this figure. Sheep make their way in the fire grounds near Bega, News South Wales, Australia January 8, 2020.  Positive effects of fire . Grassfires are fast moving, passing in five to ten seconds and smouldering for minutes. The Intergovernmental Panel on Climate Change (IPCC) in their 2019 report on Climate Change and Land found that climate change has already affected food security and the agriculture industry due to warming, changing precipitation patterns, and greater frequency of some extreme events (high confidence). The United Nations Environment Programme (UNEP) and other members of the United Nations family will continue to use its digital platforms to share accurate information and facts about the science of climate change and how it is increasing the likelihood and intensity of extreme—and tragic—weather events like this. To understand the impact of these climatic values we conducted a preliminary analysis of the 2019/20 bushfire season and compared it with the fire seasons between March 2000 and March 2020 in the states of New South Wales (NSW), Victoria, and South Australia (SA). Eastern Australia is one of the most fire-prone regions of the world, and its predominant eucalyptus forests have evolved to thrive on the phenomenon of bushfire. Opt not to print. Are you sure you want to print? Wildfires produce fine particle air pollution, which is directly threatens human health even during relatively short exposures. The impacts of the fires on the waterways is severe, with the influx of nutrients into the waterways creating algal blooms. Lara Esposito | April 11, 2020. Ash from the fires has landed in school playgrounds, backyards, and is being washed up on Australia’s beaches and into freshwater stores and water catchments. Economic impact of Australia's bushfires set to exceed $4.4bn cost of Black Saturday. This would mean the forests achieved net zero emissions. Copyright © 2020 Elsevier B.V. or its licensors or contributors. Environmental news has been particularly hard to bear at the start of 2020. According to the Bureau of Meteorology (BOM), climate change is directly affecting the bushfires in Australia, and the fire seasons are becoming increasingly longer and more severe. There appears to be no reprieve in sight, as temperatures are expected to hit 40C on the weekend, stoking fears of more fires. Cyanobacteria produce chemicals which may cause a range of water quality problems, including poor taste and odour, and sometimes toxic chemicals. However, global warming is making bushfires burn more intensely and frequently and the 2019–2020 bushfires have already emitted 400 megatonnes of carbon dioxide into the atmosphere, according to the Copernicus monitoring programme. As the Australian bushfires rage on, the smoke from the devastation can be seen from space — and the effects felt across the globe. This loss is part of a much bigger picture of a world where biodiversity is in steep decline. New Zealand, one of Australia’s closest neighbors, is feeling the effects of the bushfires. Close to the fires, smoke is a health risk because it contains a mixture of hazardous gases and particles that can irritate the eyes and the respiratory system. Smoke from bushfires in Australia has drifted across the Pacific and may have reached the Antarctic, according to the World Meteorological Organization. The summer of 2019/2020 in Australia has been characterised by extreme temperatures, the growing impact of a drought that started in 2017, and destructive bushfires, the likes of which the nation has never seen before. In some cases, assets might not be replaced because of insufficient insurance coverage. Soil pollution a risk to our health and food security, With over 1 million species currently facing extinction if we continue with business as usual, according to the World Meteorological Organization, Why African youth matter in global environmental discourse. Add to it the loss of life, personal trauma, loss of invaluable personal possessions and destruction of scientific equipment and data from the Mt Stromlo Observatory, and th… Very large text size Australia's GPs warn the mental and physical health consequences of the COVID-19 pandemic and bushfires will be severe and demand radical reforms to cope with the long years of … With habitats destroyed the true scale of loss won’t be clear for some time. The fires have disrupted tourism and agriculture, w… Victoria had a season with the highest number of fires, area burned, and second highest numbers of houses lost for the same period. This was followed shortly after by the COVID-19 pandemic which resulted in governments around the world, including Australia, instigating unprecedented restrictions to mitigate its spread. During a blaze, plumes of smoke, ash and other debris catch on the wind and scatter across the landscape. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. Impact of Australia's catastrophic 2019/20 bushfire season on communities and environment. As a result of intense smoke and air pollution stemming from the fires, in January 2020 reports indicated that Canberra measured the worst air quality index of any major city in the world. Wildfires produce harmful smoke which can cause fatalities. In some dryland areas, increased land surface air temperature and evapotranspiration and decreased precipitation amount, in interaction with climate variability and human activities, have contributed to desertification. Photo by: REUTERS/Tracey Nearmy / 22 Jan 2020. Australia is already the driest continent on the planet, and one of the countries most vulnerable to climate change in the developed world. Some communities found themselves unable to evacuate quickly when lost electricity meant fuel stations weren’t operational or blocked roads kept people trapped in high risk areas. Here are 10 good news stories that resulted from the Australia fires. This is a deeply concerning climate feedback loop. Especially in regards to the Australia bushfires. In addition to loss of life, homes and business assets have been destroyed, livestock and native animals have perished, and forestry and natural assets have burned. Algae absorb oxygen in the water in order to grow, and deplete dissolved oxygen when they die and decompose, which can asphyxiate fish and other marine life, with localized impacts to biodiversity. Here’s a (nonexhaustive) list of their short- and long-term effects on the environment. Queensland Tourism and the effects of the Australian Bushfires What is the current situation of the Australian bushfires? The associated oxygen drop and temperature rise leads to mass fish kills and aff… Australia’s bushfires have released 400 megatons of carbon dioxide into the atmosphere, according to the European Union’s Copernicus Atmosphere Monitoring Service. Reports indicate that the country’s dairy supply will likely be hit hardest, with Victoria and New South Wales—Australia’s key milk-producing states—suffering the greatest loss of farmland and infrastructure damage. 2019/20 Australia's bushfire season (Black Summer fires) occurred during a period of record breaking temperatures and extremely low rainfall. Photo by: REUTERS/Alkis Konstantinidis. Black Summer fires confirmed existing trends of impact categories during the last two decades for NSW and Victoria. Smoke from wildfires can travel great distances. The price tag to the Australian economy is still being analyzed, but it’s clear that infrastructure has been damaged and that impacts extend to industries such as farming and tourism. Infastructure damage during the 2019-2020 Australian bushfire season. Picture by Mark J Toomey, Pixabay. Analysis of acute effects showed children maintained their levels of physical activity up to an estimated turning point of air quality index of 737.08 (95% CI = 638.63, 835.53), beyond which daily physical activity levels dropped sharply. The bushfires have killed eight people and destroyed 700 homes. ET Though bushfires are not uncommon in Australia, they are usually of a lower scale and intensity that only affect small parts of the overall distribution of where species live. Home > Papers > The Effects of the Australian Wildfires on Native Species. Some were forced to seek safety on beaches and on boats, sheltering children overnight while witnessing unprecedented firestorms. Data showed that they were unprecedented in terms of impact on all areas. According to the World Health Organization, older people, people with cardiorespiratory diseases or chronic illnesses, children, and people who work outdoors are particularly vulnerable. The bushfires have not only been made more likely and intense by climate change, they also add to it. This has led to hazardous air quality in major cities throughout Australia, and affected New Zealand and cities in South America after smoke reached both Argentina and Chile. In severe fire seasons the damage caused by bushfires is astronomical. Fires do not only cause physical harm; many people experience mental trauma from the experience of emergency evacuation and losing homes, pets, belongings, livestock or other sources of livelihoods. In recent months, bushfires have devastated many regional communities. Sometimes they blow over the ocean, where they add nutrients. Exposure to particulate matter is the main public health threat from short-term exposure to wildfire smoke. Bushfires and grassfires are common throughout Australia. The bushfires will likely have further serious effects on Australia’s river systems, which could exacerbate the dangers to the duck-billed platypus. Drinking water catchments are typically forested areas, and so are vulnerable to bushfire pollution. 1. People wear breathing masks to protect themselves from a thick smoke haze from the bushfires, in Melbourne, Australia January 14, 2020. The remains of a burnt-out property which was impacted in late December 2019, in Bruthen South Victoria, Australia, January 4, 2020. Photo by: AAP Image/James Ross via REUTERSÂ. Bushfires have had a terrible impact on Australia. Increased nutrient concentrations can stimulate the growth of cyanobacteria, commonly known as blue-green algae. Bushfire ash contains nutrients, such as nitrogen and phosphorous. While Australians are reported to have been subject to misinformation campaigns and targeted attempts to undermine the link between climate change and more intense bushfires, this bushfire season has given Australians, and the watching world, an insight into the humanitarian, ecological and economic catastrophes of a changing and warming climate. The Terrible Consequences of Australia’s Uber-Bushfires Scientists calculate that the unprecedented wildfires burned 37,500 square miles. Fire is often associated with negative impacts on the environment. By March 2020 Black Summer fires burnt almost 19 million hectares, destroyed over 3,000 houses, and killed 33 people. So, when forests burn, the biodiversity on which humans depend for their long-term survival also disappears in the inferno. With over 1 million species currently facing extinction if we continue with business as usual, extreme weather events such “megafires” become an increasing matter of concern for species survival. Bushfires in Australia are a widespread and regular occurrence that have contributed significantly to shaping the nature of the continent over millions of years. A number of mega-fires occurred in NSW resulting in more burned area than in any fire season during the last 20 years.

Until the 2019–2020 Australian bushfire season, the forests in Australia were thought to reabsorb all the carbon released in bushfires across the country. We are losing wildlife at an ever-increasing scale across the planet, with impacts to ecosystems vital for our own global food production. About 13 per cent of the national sheep flock is in regions that have been significantly impacted and a further 17 per cent in regions partially impacted, according to Meat & Livestock Australia. Beginning in September 2019, bushfires burnt across eastern and southern Australia, affecting large areas of both native forests and commercial plantations.
