20 July 2016, CSIRO Blog, Supersonic magnesium. It’s used to make our smartphones and cars, and it makes our fireworks go off with a brilliant bang. It’s the third most commonly used structural metal and comprises 2% of Earth’s crust. We are of course talking about magnificent magnesium. Why do we think it’s so magnificent? Well, when magnesium is mixed with other metals it makes stable, super-strong alloys. Not only are these alloys used in our mobile phones and laptops, they are also highly sought after by car manufacturers who are turning to the metal as a solution for making lightweight, low-emission vehicles. Australia is sitting in the driver’s seat to deliver new, improved, ‘supersonic’ magnesium metal and take advantage of our vast untapped reserves of magnesite. So we’ve decided to take the wheel and develop an innovative technology, known as MagSonic, which produces magnesium using up to 80 per cent less energy and up to 60 per cent less carbon dioxide emissions than traditional processes. The process involves heating magnesia (magnesium oxide) with carbon to extreme temperatures to produce magnesium vapour and carbon monoxide. The gases are then passed through a supersonic nozzle – similar to a rocket engine – at four times the speed of sound. This cools the gases in milliseconds, condensing and solidifying the magnesium vapour to magnesium metal. Read More here

20 July 2016, The Guardian, Why is the World Bank backing coal power in Europe’s youngest country? In the early days of December 2015, as the Paris climate talks veered off course and off schedule, the US secretary of state John Kerry left his team of negotiators and flew to Kosovo to voice his support for a proposed US-built, World Bank-sponsored coal power station. Speaking alongside the prime minister, Isa Mustafa, Kerry told reporters at Pristina airport that the Kosovo e re (New Kosovo) plant would help the tiny, impoverished country do “its part to contribute to this global effort of nations who are committed to dealing with climate change” by replacing an extremely high-polluting cold war-era power plant. Kerry then returned to Paris and helpedland a deal intended to bring the fossil fuel era to an end. While many countries, including the US, continue to build coal plants at home, the fuel is increasingly a pariah in the world of development finance. Both the USand the World Bank have limited international finance for new coal power to exceptional circumstances – so rare that Kosovo’s is the only coal plant being considered for World Bank support anywhere on Earth. Despite this, Kosovan government officials are confident they will receive final approval from the World Bank when the project goes before its board, likely later this year. Strong advocacy is expected from the US delegation. Read More here
20 July 2016, Carbon Brief, In the latter half of the 20th century, the tip of the Antarctic Peninsula was among the fastest warming places on Earth. But since the late 1990s, this fast-paced warming has been tempered by extreme natural forces, according to new research. So much so, that some parts have switched to cooling. In many ways, the results are unsurprising. Scientists know that natural variability superimposes temporary ups and downs on top of greenhouse gas-induced warming everywhere on Earth. Prof Robert Mulvaney, part of the team of British Antarctic Survey scientists who carried out the research, tells Carbon Brief: “The results are as we would expect.” The authors of the study, published today in Nature, also stress their findings are restricted to a small part of the Antarctic Peninsula, and do not imply cooling across the ice sheet as a whole.

20 July 2016, Climate News Network, Humans play high-risk ecological roulette. Analysis of millions of records by thousands of scientists across the world shows that human impacts have helped push the planet’s vital biodiversity into the danger zone. Humans have reduced biodiversity – the teeming variety of plant and animal life that competes and co-operates in every ecosystem – tobelow safe levels across more than 58% of the planet’s land surface. This is ultimately bad news for human food security because biological diversity underwrites what naturalists call the resilient ecosystem services on which humans and all higher animals depend – crop pollination and pest control, nutrient decomposition and recycling, water and air purification − and because that 58% of the terrestrial planet is home to 71% of all humans, That humans are reducing biodiversity − and at a cost to the disturbed ecosystems − is not news. Separate research teams have repeatedly warned of thedangers of extinction of species. Biggest picture But Tim Newbold, a bioscience research associate at University College London, and colleagues report in Science journal that instead of drawing conclusions from one or a series of studies, they looked at the biggest picture available. The research, which is part of a British partnership study called PREDICTS, analysed 2.38 million records made by other scientists of 39,123 species at 18,659 places. Read More here
