5 June 2016, Climate News Network, Europe’s floods come as no surprise. Scientists have warned that the extra moisture in warmer air will mean more intense rainfall, but floods still leave governments unprepared. At least 18 people have lost their lives in central Europe as severe floods engulf the continent from France to Ukraine. In Paris the River Seine reached 6.1 metres (20 feet) above normal, and tens of thousands of people have fled their homes. If the downpours and swollen rivers came as a surprise, they shouldn’t have done. Not only are there historical precedents for disastrous floods. There have beengraphic recent warnings too, spelling out the growing likelihood that the warming climate will make bouts of flooding and other extreme weather more frequent. Last March a study reported in the journal Nature said climate change was already driving an increase in extremes of rainfall and snowfall across most of the globe, even in arid regions. The study said the trend would continue as the world warmed. The role of global warming in unusually large rainfall events in countries from the United Kingdom to China has been hotly debated. But this latest study showed that climate change is driving an overall increase in rainfall extremes. Its lead author, Markus Donat, a climate scientist at the University of New South Wales in Australia, said: “In both wet and dry regions, we see these significant and robust increases in heavy precipitation.” “It is probably a good idea to invest in infrastructure that helps in dealing with heavier precipitation” Warm air holds more moisture, and global warming is already increasing the odds of extreme rainfall. “The paper is convincing and provides some useful insights,” said Sonia Seneviratne, a climate scientist at the Swiss Federal Institute of Technology. “What is particularly new in this article is the demonstration of such a signal for observed changes in dry regions.” Read More here

23 May 2016, The Conversation, Coastal law shift from property rights to climate adaptation is a landmark reform. Coastal management in Australia is subject to competing interests and challenges. These range from land use and strategic planning issues to ecosystems preservation. Local councils are at the coalface as both key decision-makers and the first point of contact for communities. Exacerbating these day-to-day challenges for councils are risks to property. A quantitative assessment undertaken by the then-Department of Climate Change in 2009 identified impacts of sea-level rise as a serious threat to property. In New South Wales, under scenarios of a 1.1-metre sea-level rise, risks of damage or inundation to residential housing alone affected tens of thousands of properties, potentially costing millions of dollars. The NSW 2009 sea-level rise policy (now repealed) saw coastal councils considering this future risk when developing coastal zone management plans. These metrics, while important, say little of the wide-ranging benefits of a freely accessible coast. Going to the beach is a fundamental part of Australian identity; it’s a “special place” for Australians. Local councils are most exposed to the issues and challenges of a changing coastline in which there are many interests. Councils are often the first decision-makers for local development, asset management and land-use and strategic planning. Increased coastal erosion, storm events, more frequent and severe flooding impacts and higher tides can and will make these regular functions of councils more complicated. In this context, the tabling of the NSW Coastal Management Bill on May 3 marks the formalisation of Stage 2 of the most significant law reform to coastal management since the 1970s. The NSW state government saysthat, by better integrating coastal management with land-use planning, the legislation offers: … a modern, coherent coastal management framework that is responsive to current needs and future challenges.

April 2016 GrowthBusters: Great news about progress in questioning the worship of perpetual economic growth! The UK Parliament has officially convened an “All-Party Parliamentary Group on Limits to Growth.” This collection of members of the House of Commons and the House of Lords will “create the space for cross-party dialogue on environmental and social limits to growth; assess the evidence for such limits, identify the risks and build support for appropriate responses; and contribute to the international debate on redefining prosperity.” This should be headline news around the world. I’ve always said elected officials will be the last to adopt 21st century thinking about true sustainability – especially the unsustainability of economic growth; it appears they are finally getting on the bus. This is a truly significant step. Be sure to check out the new publication prepared for this launch, Limits Revisited: A Review of the Limits to Growth Debate.

21 April 2016, ECOS/CSIRO, Systematically addressing disaster resilience in Australia could save billions. The cost of replacing essential infrastructure damaged by disasters will reach an estimated $17 billion in the next 35 years, 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 within the total economic cost of disasters. In 2015, the total economic costs of disasters exceeded $9 billion, a figure that is projected to double by 2030 and reach $33 billion per year by 2050 – funds that could be spent elsewhere on other major national projects. During the Roundtable’s launch of the reports at Parliament House last month, risk expert and CEO of reinsurer Munich Re, Heinrich Eder, noted that 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.
