22 August 2016, Renew Economy, Gas bubble looms as energy ministers baulk at zero emissions target. State and federal energy ministers hailed progress they made in their COAG Energy Council summit late last week, but they may have condemned Australia to another great big investment bubble – this time in gas infrastructure. The meeting of ministers – brought forward by the apparent energy “crisis” in South Australia – resulted in a couple of promising steps that may help contain price surges of the type seen in recent months, but it seems to have ducked action on the critical issues. On the plus side, there is the creation of two new gas trading hubs that might improve transparency into a notoriously opaque market, and the potential for a new electricity inter-connector linking NSW and South Australia to be bought forward. But elsewhere, not a lot of tangible progress was made. The ministers baulked at calls to write zero net carbon emissions into the electricity market goals, despite that being implicit in the Paris climate goals that Australia has signed up to.And if the energy ministers did avoid turning the meeting into an anti-renewable jihad – as they were lobbied to do and might have been tempted under a previous federal energy minister – they did come face to face with some of the significant barriers to the rapid transition to a low emissions grid that they profess to support. One such example came from the Australian Energy Market Operator, whose chairman Anthony Marxsen stunned the audience on Friday when he suggested during a presentation that battery storage technology could be up to 20 years away from making a commercial contribution. Some dismissed this as garbage and a plug for the gas industry. AEMO is 40 per cent owned by industry “players”. Another is the painfully slow progress from the main policy maker, the Australian Energy Market Commission, which has been dragging out crucial rule changes most people believe are essential to moving to new technologies.

19 August 2016, Washington Post, ‘Climate change is water change’ — why the Colorado River system is headed for major trouble. There’s good news and bad news for the drought-stricken Colorado River system, according to projections just released in a new federal report from the Bureau of Reclamation, manager of dams, power plants and canals. The report predicts that Lake Mead — the river system’s largest reservoir, supplying water to millions of people in Nevada, Arizona, California and Mexico — will narrowly escape a shortage declaration next year. But a shortage is looking imminent in 2018, and water experts are growing ever more worried about the river system’s future. The Colorado River basin has been plagued with drought for 15 years now, and the effects are starting to show. Earlier this spring, Lake Mead — which feeds 90 percent of the water supply in Las Vegas, alone — dropped to its lowest levels since the Hoover Dam was completed in 1936. In fact, the last time the lake was at full capacity, with water levels 1,225 feet above sea level, was in 1983. Since then, and particularly since the year 2000, its surface levels have been steadily dropping, leaving behind a striking white “bathtub ring” around the shoreline showing how the water levels have decreased over the years. Currently, demand on Lake Mead has been removing more water than is being replenished, resulting in a deficit of about 1.2 million acre-feet, or about 400 billion gallons, each year. According to federal guidelines, a shortage is to be declared at the start of any given year if Lake Mead’s water levels have sunk below 1,075 feet above sea level. The new federal projections, spanning the next 24 months, suggest that the elevation will be hovering just below 1,079 feet at the end of this December. Read More here
19 August 2016. Climate News Network, Internet energy impacts on climate. New research warns that the growing reliance on smart technologies is leading to a rapid rise in internet energy demand that will push up carbon dioxide emissions. Switch off your computer, dust off your old typewriter, sharpen all the pencils you can find, lay in stocks of postage stamps − and that’s just the start. Our immersion in the digital society – and particularly our growing reliance on the Internet of Things – could mean uncontrolled demand for energy and spiralling emissions of carbon dioxide and the other greenhouse gases that are driving climate change. Researchers from the School of Computing and Communications (SCC) at the University of Lancaster, UK, say the growth of remote digital sensors and devices connected to the internet – the Internet of Things – can cause unprecedented and, in principle, almost unlimited rises in the energy consumed by smart technologies. They warn that the world now needs to consider how to limit data growth on the internet. Read More here
18 August 2016, New Internationalist, Climate change and colonial history make a toxic combination. New research points to a powerful link between climate change and armed conflict. It also finds that countries that are ethnically mixed are more likely to experience this kind of conflict. But their results may actually tell us more about the consequences of colonialism than ethnic diversity. This new research joins a raft of existing research on climate change and conflict – often reaching competing conclusions. What is the link between climate change and conflict? This isn’t an issue that can be solved with one study. There are in fact hundreds of studies looking at this issue. And they don’t all reach the same conclusion. Some studies do show that climate impacts lead to increased violence. But some studies find that there was actually no connection at all. Being hit by a disaster or climate change impacts didn’t make any difference to levels of violence. Some studies even found the opposite. Climate change impacts actually reduced some kinds of violence. So what happens when we look at all this research as a whole? Yes, some of the studies point in different directions. But what about when we consider all the research together? Does it point to powerful climate – conflict connection, or not? It still isn’t clear. Read More here
