17 March 2016, Renew Economy, What will shake Malcolm Turnbull from his climate coma? First, the good news. According to the International Energy Agency, energy-related carbon dioxide emissions stayed flat for the second year in a row in 2015 – a clear sign that the nexus between economic growth and increasing energy emissions has been broken.The IEA says that the two biggest economies and energy consumers, the US and China, both achieved significant cuts in the last year (by 2 per cent and 1.5 per cent respectively), as coal-fired generation was replaced by gas in the US, and by wind and solar and energy efficiency in both countries. And the world can do more, says the International Renewable Energy Agency. By doubling its capacity in renewable energy – principally wind and solar – by 2030, the world can keep on track to meet its Paris climate targets, save $4.2 trillion in fuel, boost its GDP by $1.3 trillion and generate some 9 million jobs. Too easy. But here’s the bad news. While the world’s two biggest emitters are managing to bring their energy emissions under control, those of Australia are continuing to soar – by around 4.5 per cent since the Coalition government dumped the carbon price nearly two years ago. Coal generation, declining in US and China, is rebounding in Australia. Large-scale renewable energy investment has come to a complete standstill under any policy over which the Coalition government has control. Indeed, it is nearly a year since a compromise deal was reached on the large-scale renewable energy target – cutting it from 42,000GWh to 33,000GWh, and more than six months since Malcolm Turnbull raised hopes of a turnaround when he became prime minister. Turnbull declares himself entirely satisfied with the status quo, possibly encouraged by the fact that while 47 per cent of people say that climate and clean energy policies might influence their vote, more than half say it won’t. “We have effective and responsible climate change policies that are working,” Turnbull told parliament on Wednesday. “We are on track to beat and meet our 2020 emission reduction target. Our 2030 target is responsible and in line with that of comparable countries.” Turnbull was speaking in response to a question from Greens MP Adam Bandt, who asked if Turnbull agreed with the assessment of chief scientist Alan Finkel, who on the same day that new data showed a stunning rise in average global temperatures, said that under current policies we are losing the battle against climate change?

16 March 2016, The Conversation ,Droughts and flooding rains: it takes three oceans to explain Australia’s wild 21st-century weather. Australia is a land of extremes, and famously of “droughts and flooding rains”. That’s been truer than ever in the 21st century; since 1999 the country has see-sawed from drought to deluge with surprising speed. There was the millennium drought, which lasted more than a decade and culminated in disasters such as Victoria’s Black Saturday bushfires in 2009. Then, in 2011, Cyclone Yasi struck Queensland and a large swathe of Australia exploded under a green carpet of grasses, shrubs and trees. Filming of the movie Mad Max: Fury Road was moved from outback Australia to Namibia after the big wet of 2010-11, because Australia’s luxurious growth of wildflowers and metre-high grasses didn’t quite match the post-apocalyptic landscape the movie’s producers had in mind. In Alice Springs, the Henley-on-Todd Regatta was almost cancelled in 2011 because there was water in the normally dry river. Globally, the big wet on land caused a 5 mm drop in sea levels as large amounts of rain were deposited on Australia, South America and Africa. This coincided with an unprecedented increase in carbon stored in vegetation, especially in arid and semi-arid regions of the southern hemisphere. The greening of Australia in particular had a globally significant impact. Meteorologists have struggled to explain these wild variations in Australia’s weather. Dry years with disappointing crops have been linked to the Pacific Ocean’s El Niño phase (part of a cycle called the El Niño-Southern Oscillation (ENSO)). But despite its huge influence, not even ENSO can fully account for Australia’s extreme rainfall patterns. Our research, published this week in Nature’s Scientific Reports, offers an explanation. We found that conditions in the three oceans that surround Australia – the Pacific, Indian and Southern Oceans – combine to amplify each other’s influences on Australian weather. Read More here
16 March 2016, The Conversation, Hot cities: the ‘smart’ response to urban heat threats. Significant urban policy and planning efforts have been directed at the problem of rising heat in cities. “Smart” cities create new relationships and interdependencies between people, technology and urban environments. The concept rests on the efficient, responsive and adaptive capacities of urban infrastructure. But how well does the smart city respond to the devastating scale and impact of urban heat threats such as bushfires and heatwaves? The Australian Medical Association has warned heat is a “silent killer”. It notes that more Australians die each year due to heat than on the roads. Heatwaves have contributed to more deaths in Australia than any other natural disaster. Bushfires are also expected to increase, with significant impacts on Australian cities and urban communities such as the greater Melbourne region. This is a pressing issue for Australian cities and urban regions, at a time when Australian climatologists are warning of the increasing frequency, severity and duration of heatwaves and bushfires. Smart urban infrastructure New digital technology is entering cities, homes and workplaces. These are performing complex tasks. Self-driving cars and cashless payment systems are examples of significant change. But they also increase a city’s vulnerability in the event of a system breakdown or failure. The ways that these dependencies make cities highly vulnerable during a crisis are poorly understood. For example, smartphone-enabled bushfire and heatwave warning systems are one of the key policy responses proposed and trialled as part of the smart city. But, the benefits and challenges of such responses are still largely unknown. While the invisibility of smart city technology and infrastructure may rise to the surface and become exposed in the face of urban heat-related threats and crises, an array of important considerations lurk in the shadows.

15 March 2016, Renew Economy, Hunt caught out on “peak emissions”, but he may have a cheap solution. As new NASA data reveals global temperature records were smashed by a “stunning” margin in the month of February, new research from carbon market analysts RepuTex has found that Australia’s contribution to curbing global warming could be easier and cheaper than we thought. The study, published on Tuesday has found more than half of Australia’s 2030 emissions reduction target able to be met using “cheap and abundant” domestic abatement – debunking the well established policy myth that the lowest-cost path for Australia was to buy cheap international offsets. The conclusion was reached in a new approach to modelling based on what RepuTex has dubbed the “real world supply cost curve”. It found that more than 300 million credits could be created by local Australian companies over the next seven years at around $1-$4 per credit, while more than 500 million credits could be supplied at less than $20. As RepuTex executive director Hugh Grossman told RenewEconomy in a telephone interview on Tuesday, “that’s a lot” – particularly when you consider the government’s calculations that it needs 900 million tonnes of abatement to meet its emissions reduction 2030 target. And it’s significant, he notes, in that it changes the game for how Australian policy might be designed to achieve emissions cuts: using local emissions reductions, at low cost, without relying on international offsets, all while keeping the cost of compliance low for industry……. Indeed, far from encouraging business and industry to cut emissions, federal environment minister Greg Hunt is busy reassuring us all that Australia’s greenhouse gas emissions actually “peaked” 10 years ago. “I believe that we have reached what is sometimes known as peak emissions,” Hunt told ABC Radio’s AM program. “My best estimate is that we are unlikely as a nation ever to surpass [2005 levels] … In my best judgment, the advice, the information from the department, we reached peak emissions in 2005-06 … and the course of history to come for Australia is that we will continue to be below that figure.” The comments – described by Climate Institute CEO John Connor as “extraordinary”, particularly in light of “the enormous credibility gap in the government’s current policies” – were quickly dismissed by Grossman, who says his company’s analysis of the government’s own data shows Australia’s emissions will continue to grow, with “no peak in sight”.
