8 March 2016, Renew Economy, Government somnolence on climate change health costs. Climate change is described by leaders of the medical profession as the greatest health risk of this century. Its health impacts are already significant both internationally and in Australia and are predicted to increase with rising temperatures. The severity of natural disasters from extreme weather events is increased by climate change and is an important cause of harms to our health. A report prepared for the Australian Roundtable by Deloitte Access Economics on the costs of these disasters is remarkable in exposing the health costs. It requires dedicated government attention and action if many Australians are to be spared unnecessary harm and suffering. In 2015 the social costs of natural disasters were at least equal to the physical costs in a total of over $9 billion — about 0.6% of gross domestic product. The total cost of disasters is expected to rise to an average of $33 billion per year in real terms by 2050 unless steps are taken to increase resilience and address mitigation. However, as the report indicates, these costs are calculated without considering the potential impact of climate change. This report “assumes natural hazards will be as frequent in the future as in the past. Given the evidence for climate change, this is unlikely to be the case – extreme weather events will probably occur more regularly in the future than in the past” It is not difficult to calculate the tangible costs of disasters, the damage to infrastructure of buildings, roads, land and crops but the importance of the new Report lies in its costing of the intangible damage to people, the health and well being of the affected community-the lives destroyed from an increase in mental health issues, family violence, alcohol consumption, chronic and non-communicable diseases and short-term unemployment.

7 March 2016, Climate News Network, Climate query as US tornado risk rises. Scientists say the climate behaves too capriciously for them to know for sure whether global warming caused by burning fossil fuels is to blame for a growing tornado threat. Tornadoes in the US are getting worse, with the numbers in any one outbreak and the hazard of ever more frequent outbreaks both on the increase. And although climate change driven by global warming from human causes is under suspicion, nobody really knows for sure whether that is driving the pattern of change. But change is certainly happening. New research published in Nature Communications has examined the pattern of outbreaks and found that the average number of tornadoes in any one outbreak has increased since 1954, and the chance of extreme – and therefore extremely destructive – outbreaks has also increased. An outbreak is a large-scale weather event that can last for days, span huge regions and spawn multiple tornadoes. Continental America is used to these outbreaks, which is why a band of territory that spans central Texas, Illinois and Indiana, and embraces parts of Oklahoma, Kansas, Nebraska, Colorado and South Dakota, is known as Tornado Alley.

1 March 2016, Science Daily, Impact of climate change on public health. Health consequences of climate change: Doctors urge action to help mitigate risks and prepare for new challenges. Climate change is already having a noticeable impact on the environment and global health. Around the world extreme weather events, increased temperatures, drought, and rising sea levels are all adversely affecting our ability to grow food, access clean water, and work safely outdoors. Soon in some areas, the transformation will be so drastic and devastating that native populations will be displaced and forced to find new homes as environmental refugees. In a review published in theAnnals of Global Health, doctors warn of the impending public health crisis brought on by climate change and call for action to help prepare the world for what is ahead. As we begin to experience an unprecedented shift in temperature, we are starting to see the immense impact climate change will have on people around the world, especially those living in low-income countries. Bearing the brunt of the damage caused by climate change, low-income nations are especially susceptible because their economies often rely solely on agriculture and most do not possess the resources to ease the risks posed by climate events. Low-income countries contribute just a tiny fraction of greenhouse gases (GHG), yet, they stand to lose the most if something is not done to curb emissions. In 2004, the United States, Canada, and Australia approached 6 metric tons (mt) of GHG per capita, while per-capita GHG emissions in low-income countries was only 0.6 mt overall. “As global temperature increases, rich countries’ economies continue to prosper, but the economic growth of poor countries is seriously impaired,” explained co-author Barry S. Levy, MD, MPH, Adjunct Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine. “The consequences for economic growth in poor countries will be substantial if we continue on a ‘business-as-usual’ path of increasing carbon dioxide concentrations and rapid climate change, with poor countries’ mean annual growth rate decreasing from 3.2% to 2.6%.” Read More here
22 February 2016, Renew Economy, Failure to include health risks grossly distorts true costs of climate change. Climate change is above all a question of public health. Although spared from famine and civil disruption that will afflict other countries, Australians increasingly will be exposed to the effects of extreme weather patterns consequent to our heating climate, and they will as a result suffer more ill health requiring attention from GPs and hospitals. Heat waves lead to heat stroke, increase heart attacks, cause dehydration and threaten those with renal impairment; fires threaten life in so many ways; floods and wild storms can cause drownings and other injuries; and all these events lead to distress and affect long-term mental well-being. Children especially, but also adults, can suffer from sleep disturbances, aggressive behaviour, sadness, substance abuse and post-traumatic stress disorder. Children are also vulnerable to extreme weather events because such events interrupt their safety, their sense of security and their access to the outside world. Hotter days will bring more asthma, and, in some localities, more exposure to local mosquito-born infectious diseases. This cannot be what we want for our children. Disturbingly, our health system infrastructure and resources can also be affected by more severe and frequent extreme weather events, thus potentially limiting their ability to provide care when it is needed most. For example, in the heat wave before the Black Saturday bushfires, 25 per cent of all hospitals had problems with their air-conditioning or cooling systems. Political leaders, by ignoring the impacts of global warming on health, have hindered public discourse and concerted action on climate change despite the urgency to act. The failure to include health costs distorts the costs to families and communities, as well as the bottom line on already-stretched health budgets. What is already well known by economists, for example, is that the health costs of coal and fossil fuel burning increase societal costs of electricity (double or more by some estimates) – surely an incentive to escape from the fossil fuel addiction. The Morwell coalmine fire in Victoria would be another route by which society is damaged by use of fossil fuels. As a medical organisation, Doctors for the Environment Australia is frustrated by the dismal failure of governments and our senior leaders to include the health risks and costs in the numerous discussions on climate change.
