31 July 2016, Scientific American, The Sticky Truth about Economic Growth and Climate Change. Why we need to talk about the costs of mitigation. That averting climate change will save us money should be a tautology, but for reasons including entrenched interests, it is not. The pre-cautionary principle alone would tell us that we do not want to learn what costs climate change will incur, so better to pay a small premium to avoid the risk at all. Instead, calculated estimates pin the cost of avoiding catastrophic effects from climate change at something like 1% of global GDP. So who will pay for it, and who loses from a more sustainable economy? In recent years, several studies have come out running cost-benefit analysis on a policy switch to a clean energy system. Yet, besides governmental ‘push’ factors, we should not forget market ‘pull’ factors. Even if there was less of a push by the government to clean up our air and water supply, as well as mitigate climate change, the coal industry is for example changing regardless thanks to cheap natural gas as well as self-inflicted wounds. While coal mine employment in the U.S. did drop 91,600 in 2011 to 74,900 in 2014, there are now more workers in the solar sector than in oil and gas. So overall, not counting the benefits of lowered air pollution and avoiding climate change, the overall job situation seems to be moving towards net positive. So, case closed? Not quite.

19 July 2016, Renew Economy, Frydenberg’s choice: Make a big step forward, or a big step back. The make-up of Australia’s new parliament cut a depressing vista on Monday. There was Pauline Hanson, demanding royal commissions into Islam and climate science, who along with other minor party and independent Senators will most likely hold the balance of power in the Senate, with as many as 7 seats but a minimum of 3. In the government, the Coalition led by Malcolm Turnbull has elevated more conservatives to the front bench. Zed Selseja, a conservative who opposes gay marriage and weekend penalty rates, is minister assisting social services.Hanson gave us a taste of what is to come in an extraordinary debate on ABC’s Q&A, which was punctuated with the sort of ignorance and ideology we often see in the energy sector – see South Australia. Matt Canavan, a conservative who dismisses climate science, is appointed resources minister responsible for the coal industry and building dams in northern Australia. Be under no doubt about Canavan: the only energy that matters to him, he has said often, is cheap energy, dirty or not. Read More here
16 July 2016, Climate News network, Cyclones set to get fiercer as world warms. New analysis of cyclone data and computer climate modelling indicates that global warming is likely to intensify the destructive power of tropical storms. Powerful tropical storms − known variously as cyclones, typhoons and hurricanes − bring death and destruction to huge swathes of the Earth’s surface. And new research suggests that they are likely to become even stronger. Storms such as the super-typhoon Nepartak that scoured Taiwan earlier this month with winds of 150 miles per hour and then flooded parts of China, are expected to grow even fiercer as the planet warms. That trend is not clear yet, but scientists in the US say it soon will be. Ironically, one of the main reasons why these storms will gain in power is theeffort in many countries to reduce air pollution. Damaging as it is in stunting and shortening lives, the one arguable benefit of filthy air is its ability to dampen the effects of greenhouse gases (GHGs) on cyclones and their like. Over the last century, tiny airborne particles called aerosols, which cool the climate by absorbing and reflecting sunlight, have largely cancelled out the effects of GHG emissions on tropical storm intensity, according to a new scientific review paper published in Science journal.

5 July 2016, Renew Economy, Hidden climate report could help Malcolm find the middle. The Climate Change Authority report that some suspected was buried by the Australian government to save it from policy embarrassment during the election campaign, could now make it easier for prime minister Malcolm Turnbull to find the middle ground in a minority government, or one ruling with a razor-thin majority. The CCA report had been expected to be released in late June, but was delayed until after the election, to the obvious relief of the government. So, too, was a report on options for the electricity sector, which had been due for release in April or May, and which leaked reports suggest strongly supported some form of mandatory carbon price. Those reports by the CCA, despite its board being stacked by Turnbull government appointees following the resignation of former chairman Bernie Fraser and other directors, would not have suited the Coalition election platform. They were expected to reaffirm the position that Australia was trailing the world in emission reductions, needed to do more, and would need to adopt a carbon price. And, they would likely note, this would not be anywhere near as expensive as many suggest. That, of course, would not have helped the Coalition election platform, which was to continue with its much criticised Direct Action program, and to lambast any proposals by Labor and the Greens for an economy-wide carbon price and higher renewable energy targets.
