25 April 2016, The Guardian, The Guardian view on the UN climate change treaty: now for some action. The danger of gala events like the official signing of the climate change treaty at the UN in New York on Friday, crowned with a guest appearance from Leonardo DiCaprio and with 60 heads of state in attendance, is the impression they create that the job is done. It was certainly a spectacular demonstration of global intent to get more than 170 signatures on the deal agreed in Paris in December at the first time of asking; but what matters is making it legally binding. For that, it must be not just signed but ratified by at least 55 countries, and it must cover 55% of emissions. Nor does the Paris deal go far enough. It was only a step on a long, hard road. The targets that each country set themselves do not go nearly far enough. Now the gap between reality and the ambition of holding global warming below 2C needs addressing. In Churchillian rhetoric, this is not the end, nor the beginning of the end, but it is the end of the beginning. Read More here

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.

21 April 2016, The Conversation, Limits to growth: policies to steer the economy away from disaster. If the rich nations in the world keep growing their economies by 2% each year and by 2050 the poorest nations catch up, the global economy of more than 9 billion people will be around 15 times larger than it is now, in terms of gross domestic product (GDP). If the global economy then grows by 3% to the end of the century, it will be 60 times larger than now. The existing economy is already environmentally unsustainable. It is utterly implausible to think we can “decouple” economic growth from environmental impact so significantly, especially since recent decades of extraordinary technological advancement have only increased our impacts on the planet, not reduced them. Moreover, if you asked politicians whether they’d rather have 4% growth than 3%, they’d all say yes. This makes the growth trajectory outlined above all the more absurd. Others have shown why limitless growth is a recipe for disaster. I’ve argued that living in a degrowth economy would actually increase well-being, both socially and environmentally. But what would it take to get there? In a new paper published by the Melbourne Sustainable Society Institute, I look at government policies that could facilitate a planned transition beyond growth – and I reflect on the huge obstacles lying in the way. Measuring progress First, we need to know what we’re aiming for. It is now widely recognised that GDP – the monetary value of all goods and services produced in an economy – is a deeply flawed measure of progress.Read More here
18 April 2016, The Conversation, Australia’s carbon emissions and electricity demand are growing: here’s why. Australia’s greenhouse gas emissions are on the rise. Electricity emissions, which make up about a third of the total, rose 2.7% in the year to March 2016. Australia’s emissions reached their peak in 2008-2009. Since then total emissions have barely changed, but the proportion of emissions from electricity fell, largely due to falling demand and less electricity produced by coal. But over the last year demand grew by 2.5%, nearly all of this supplied by coal. In 2015 I wrote about concerns that Australia’s electricity demand and emissions would start increasing again. This has now come true. So what’s driving the trend? Why did demand fall? To understand this trend we need to look at data from Australia’s National Electricity Market (NEM), which accounts for just under 90% of total Australian electricity generation. While the NEM doesn’t include Western Australia or the Northern Territory, it has much better publicly available data. The chart below shows electricity generation from June 2009 to March 2016.
The most important things to note are that, until February 2015, overall generation fell and the amount of electricity supplied by coal also fell. These two trends are closely related. Read More here
