16 March 2017, The Conversation, Year-on-year bleaching threatens Great Barrier Reef’s World Heritage status. The Great Barrier Reef has already been badly damaged by global warming during three extreme heatwaves, in 1998, 2002 and 2016. A new bleaching event is under way now. As shown in a study published in Nature today, climate change is not some distant future threat. It has already degraded large tracts of the Great Barrier Reef over the past two decades. The extreme marine heatwave in 2016 killed two-thirds of the corals along a 700km stretch of the northern Great Barrier Reef, from Port Douglas to Papua New Guinea. It was a game-changer for the reef and for how we manage it. 

 

Bleaching caused by extreme heat in summer 2016, based on extensive aerial surveys. Category 4 in red: 60-100% of colonies were bleached; Category 3 in orange: 30-60% bleached. Author provided Our study shows that we cannot climate-proof coral reefs by improving water quality or reducing fishing pressure. Reefs in clear water were damaged as much as muddy ones, and the hot water didn’t stop at the boundaries of no-fishing zones. There is nowhere to hide from global warming. The process of replacement of dead corals in the northern third of the reef will take at least 10-15 years for the fastest-growing species. The Great Barrier Reef is internationally recognised as a World Heritage Area. In 2015 UNESCO, the world body with oversight of World Heritage Areas, considered listing the reef as a site “in danger” in light of declines in its health. Australia’s response falling short.

15 March 2017, The Guardian, Renewables roadshow: how Daylesford’s windfarm took back the power. From the fertile spud-growing country of Hepburn Shire, 90km northwest of Melbourne, has sprung what many hope will become a revolution in renewable energy in Australia. On Leonards Hill, just outside the town of Daylesford – famed for its natural springs – stand two wind turbines that not only power the local area, but have also added substantial power to the community-owned renewable energy movement in Australia. The turbines, cheesily called Gusto and Gale, constitute the very first community-owned windfarm in Australia. It borrows the idea from a long tradition of community-owned power that was forgotten in Australia, but lives on strongly in Denmark. “In Denmark there’s over 2,100 versions of this,” says Taryn Lane, the community manager for Hepburn Wind, the cooperative that owns and operates the windfarm. “Their model – this way of owning your own energy generator locally – emerged in the late 70s, so they have been doing it for decades.” It was at a community meeting for a large corporate-owned windfarm, like the one near Hepburn, that the idea for Hepburn Wind emerged. Strong community opposition, often encouraged by the fossil fuel industry, has at times been a roadblock for large windfarms built by traditional energy companies. Lane says the Danish founder of Hepburn Wind, Per Bernard, attended the meeting with a few people from Daylesford, and they saw the community express a lot of opposition to one of those projects. “They were quite disappointed that that was our local area’s first response to large-scale renewables development in the area,” Lane says. Bernard figured that if they adopted the Danish model, where the windfarm was smaller, and the local community owned it, support for clean, clean wind energy would grow. The idea of communities owning their own power generators is not new in Australia, according to Lane, it’s just been forgotten. That was the way electricity was first introduced into much of the country, with smaller decentralised generators, owned by the local communities. The mayor of Hepburn Shire, Sebastian Klein agrees. “Hepburn actually used to own its own power generating sources. We used to have our own generator in the main street of Daylesford [and] we used to have our own hydro station down at the lake,” he says. Read More here

9 March 2017, The Guardian, Renewable energy spike led to sharp drop in emissions in Australia, study shows. A sharp drop in Australia’s greenhouse gas emissions at the end of last year came courtesy of a spike in renewable energy generation in a single month, according to a new study. Australia’s emissions fell by 3.57m tonnes in the three months to December, putting them back on track to meet quarterly commitments made in Paris after a blowout the previous quarter. The fall is the largest for the quarter since the government began recording emissions in 2001. The report’s authors said this was entirely due to record levels of hydro and wind generation in October. This brought emissions for the year to December to below the year to December 2015. But projected emissions for the December quarter were still 6.89m tonnes over levels demanded by scientifically based targets set by the government’s Climate Change Authority. And, long term, the results show Australia is set to run more than 300m tonnes over what is required to meet its Paris targets in 2030.
