18 March 2016, ECOS, Building disaster resilience systematically. The cost of replacing essential infrastructure damaged by disasters in the next 35 years is estimated to reach $17bn according to the latest set of reports from the Australian Business Roundtable for Disaster Resilience and Safer Communities. The reports, Building Resilient Infrastructure and the Economic Costs of Social Impact of Disasters, outline the costs associated with replacing essential infrastructure damaged by disasters and provide an overview of the direct costs of physical damage with the total economic cost of disasters. In 2015, the total economic costs of disasters exceeded $9bn, a figure that is projected to double by 2030 and reach $33bn per year by 2050 – funds that could be apportioned elsewhere on other major national projects. And as Heinrich Eder, CEO of reinsurer Munich Re, noted, these projections are based only on economic and population growth; they do not even include the increasingly detectable effects of climate change. These are big, and socially traumatic, numbers. Long-term they have the same sort of potential to create holes in national and state budgets as our ageing population does—the subject of repeated Intergenerational Reports and eventual decisions about adjusting retirement age. It is clear to us, based on our work, that investing much more in disaster resilience as a nation will reduce physical damage, avoid social disruption and trauma, and lessen this capricious burden on state and national budgets. In fact, estimates suggest that well-targeted investments in resilience could result in significant savings for the government. Read More here

11 March 2016, Science Daily, Science can now link climate change with some extreme weather events. Extreme weather events like floods, heat waves and droughts can devastate communities and populations worldwide. Recent scientific advances have enabled researchers to confidently say that the increased intensity and frequency of some, but not all, of these extreme weather events is influenced by human-induced climate change, according to an international National Academies of Science, Engineering, and Medicine report released March 11. “In the past, many scientists have been cautious of attributing specific extreme weather events to climate change. People frequently ask questions such as, ‘Did climate change cause Hurricane Sandy?’ Science can’t answer that because there are so many relevant factors for hurricanes. What this report is saying is that we can attribute an increased magnitude or frequency of some extreme weather events to climate change,” said David Titley, professor of practice in Penn State’s Department of Meteorology and founding director of Penn State’s Center for Solutions to Weather and Climate Risk, who chaired the committee that wrote the report. The committee found that scientists can now confidently attribute some heat waves and cold events, and to a lesser degree droughts and extreme rainfall, to human-caused climate change. Even a decade ago, many scientists argued that research could not confidently tie any specific weather events to climate change, which the committee reports today is no longer true today.

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.
