27 March 2017, The Guardian, Trump presidency ‘opens door’ to planet-hacking geoengineer experiments. As geoengineer advocates enter Trump administration, plans advance to spray sun-reflecting chemicals into atmosphere. Harvard engineers who launched the world’s biggest solar geoengineering research program may get a dangerous boost from Donald Trump, environmental organizations are warning. Under the Trump administration, enthusiasm appears to be growing for the controversial technology of solar geo-engineering, which aims to spray sulphate particles into the atmosphere to reflect the sun’s radiation back to space and decrease the temperature of Earth. Sometime in 2018, Harvard engineers David Keith and Frank Keutsch hope to test spraying from a high-altitude balloon over Arizona, in order to assess the risks and benefits of deployment on a larger scale. Keith cancelled a similar planned experiment in New Mexico in 2012, but announced he was ready for field testing at a geoengineering forum in Washington on Friday. “The context for discussing solar geoengineering research has changed substantially since we planned and funded this forum nearly one year ago,” a forum briefing paper noted. While geoengineering received little favour under Obama, high-level officials within the Trump administration have been long-time advocates for planetary-scale manipulation of Earth systems. David Schnare, an architect of Trump’s Environmental Protection Agency transition, has lobbied the US government and testified to Senate in favour of federal support for geoengineering. He has called for a multi-phase plan to fund research and conduct real-world testing within 18 months, deploy massive stratospheric spraying three years after, and continue spraying for a century, a duration geoengineers believe would be necessary to dial back the planet’s temperature. Geoengineers argue that such methods would be an inexpensive way to reduce global warming, but scientists have warned it could have catastrophic consequences for the Earth’s weather systems. Scientific modelling has shown that stratospheric spraying could drastically curtail rainfall throughout Asia, Africa and South America, causing severe droughts and threatening food supply for billions of people.

24 March 2017, Climate News Network, World’s reefs damaged beyond repair. Australia’s Great Barrier Reef and reefs in the Maldives have been dangerously weakened by coral bleaching caused by global warming and El Niño events. The Great Barrier Reef, one of the wonders of the Pacific Ocean, may never fully recover from the combined effects of global warming and an El Niño year, according to a new study in one of the world’s leading science journals. And a second study, in a second journal, warns that increased sea surface temperatures have also caused both a major die-off of corals and the collapse of reef growth rates in the Maldives, in the Indian Ocean. Corals are very sensitive to ocean temperatures, and in unusually hot years – and these have recurred naturally and cyclically since long before humans started burning coal, oil and gas, to accelerate the build-up of greenhouse gases in the atmosphere – the corals react to stress by bleaching. That is, they eject the photosynthesising algae that live with them in symbiosis, to the advantage of both creatures. Hotter oceans But the world’s oceans are becoming hotter anyway, because of global warming driven by greenhouse gas concentrations in the atmosphere. The seas are becoming ever more acidic as atmospheric carbon dioxide reacts with the water. And the periodic return of a blister of oceanic heat in the eastern Pacific called El Niño – Spanish for “The Child”, because it becomes most visible around Christmastime – has begun to put the world’s reefs at risk. The El Niño of 2015-16 triggered a massive episode of bleaching throughout the tropics. And, Australian researchers say in Nature, the bleaching continues. “We’re hoping that the next two to three weeks will cool off quickly, and this year’s bleaching won’t be anything like last year. The severity of the 2016 bleaching was off the chart,” says Terry Hughes, of Australia’s Centre of Excellence for Coral Reef Studies, at James Cook University in Queensland. “It was the third major bleaching to affect the Great Barrier Reef, following earlier heatwaves in 1998 and 2002. Now we’re gearing up to study a potential number four. “We have now assessed whether past exposure to bleaching in 1998 and 2002 made reefs any more tolerant in 2016. Sadly, we found no evidence that past bleaching makes the corals any tougher.” Read More here
24 March 2017, Renew Economy, Fear and loathing about renewable grid in Coober Pedy. There is uproar in Coober Pedy, the iconic mining town deep in the South Australian desert that is known as the Opal Capital of the world. What should have been a positive story about a project to shift the town from diesel to a renewable-focused mini-grid based around wind and solar and storage is causing outrage among consumers and councillors, and embarrassment to the developer and the federal agency that backed it. Last year, as we reported at the time, the final plan for the Coober Pedy Renewable Diesel Hybrid project was unveiled, featuring 4MW of wind, 1MW of solar and a 1MW/250kWh battery to provide up to 70 per cent of the power needs of Coober Pedy. The idea was that it would dramatically reduce the amount of diesel consumed from the existing 3.9MW diesel power station, reduce costs, and provide a possible blueprint for the rest of Australia to follow. But what should have been a flagship project for the country – as ARENA CEO Ivor Frischknecht touted it at the time – looks like turning into a disaster for the town and an embarrassment for the renewable energy industry; and a legal dispute between the council and the developers. It has now emerged that the cost that will be charged to the council, which owns the local grid, and which will subsidised by the government, will be more than double other alternatives. Graham Davies, from Adelaide-based Resonant Solutions, who completed an assessment on behalf of council last year, says that the average cost of generating electricity, not including distribution but including rebates, will be 48c/kWh. The deal signed by council will translate to total cost of $192 million over 20 years, a saving of a dismal $5 million over the diesel only grid staying as is for 20 years – which would simply not happen. The company’s own presentation on the project, made last May, appears to confirm that there is little difference between the ongoing cost of diesel and the solar, wind and storage grid.

24 March 2017, Renew Economy, Coalition sets climate parameters, as two more quit key advisory body. Stage one of the federal government’s 2017 review of climate change policies is finally underway, with the release on Friday of a 40-page discussion paper for public consultation. The Coalition’s climate review, announced by the Turnbull government in December 2016 and due for completion by the end of the year, was seen by some – at the time – as a positive development; an opportunity for it to get serious about its climate change policy, both current and future. But the publication of the discussion paper – almost two months behind schedule and amid claims from the federal government’s own Climate Change Authority that it “doesn’t take the issue seriously” – does not immediately inspire confidence. This week has seen not one, but two resignations from the CCA – the first being former Coalition energy advisor Danny Price, followed on Thursday by University of Queensland professor John Quiggin. The departures follow that, a month ago, of Australian ethics professor Clive Hamilton, who cited his reasons for quitting the body as the Coalition’s “perverse” and “deeply dishonest” approach to climate and energy policy. In a letter posted on his blog on Thursday, Quiggin was less diplomatic, broadly attributing his own reasons for leaving to the fact that “the (Turnbull) government is beholden to right wing anti-science activists in its own ranks and in the media.” Read More here
