4 December 2016, University of Melbourne – Pursuit, A long climatic affair. The first extensive retrospective of our climate history has traced the human fingerprint on record-breaking hot temperatures as far back as the 1930s. In recent years climate scientists have been examining what role climate change has played in unusual extreme weather events such as Australia’s hottest summer in 2012-13 and recent heatwaves. But before now, no-one had looked at how far back in time we could go and still link weird weather and record-breaking climate extremes to our influence. Our study, published in Geophysical Research Letters, addresses the question of when exactly climate change started altering the influence of record hot years and summers in a way we can detect. We looked at five regions of the world, as well as the whole globe. Human-made climate change has been influencing heat extremes for decades, with many past records directly attributable to the effect we have had on the climate. We found the last 16 record-breaking hot years globally up to 2014 were made more likely because of climate change (we didn’t include 2015 – the current holder of the hottest year record – because we performed our analysis before the end of last year).

2 December 2016, Reuters, Biggest-Ever Coral Die-Off Reported on Australia’s Great Barrier Reef. Warm seas around Australia’s Great Barrier Reef have killed two-thirds of a 700-km (435 miles) stretch of coral in the past nine months, the worst die-off ever recorded on the World Heritage site, scientists who surveyed the reef said on Tuesday. Their finding of the die-off in the reef’s north is a major blow for tourism at reef which, according to a 2013 Deloitte Access Economics report, attracts about A$5.2 billion ($3.9 billion) in spending each year. “The coral is essentially cooked,” professor Andrew Baird, a researcher at James Cook University who was part of the reef surveys, told Reuters by telephone from Townsville in Australia’s tropical north. He said the die-off was “almost certainly” the largest ever recorded anywhere because of the size of the Barrier Reef, which at 348,000 sq km (134,400 sq miles) is the biggest coral reef in the world. Bleaching occurs when the water is too warm, forcing coral to expel living algae and causing it to calcify and turn white. Mildly bleached coral can recover if the temperature drops and the survey found this occurred in southern parts of the reef, where coral mortality was much lower. Read More here
2 December 2016, The Guardian, After 60 years, is nuclear fusion finally poised to deliver? “We are standing on the ground that could change the future of energy,” says engineer Laurent Pattison, deep in the reactor pit of the world’s biggest nuclear fusion project. Around him is a vast construction site, all aimed at creating temperatures of 150mC on this spot and finally bringing the power of the sun down to Earth. The €18bn (£14.3bn) Iter project, now rising fast from the ground under the bright blue skies of Provence, France, is the first capable of achieving a critical breakthrough: getting more energy out of the intense fusion reactions than is put in. “It is a bet that is very important for humanity,” says Johannes Schwemmer, the director of Fusion for Energy, the EU partner in the international Iter collaboration. “We need to get this energy once and for all.” The long allure of nuclear fusion is simple: clean, safe, limitless energy for a world that will soon house 10bn energy-hungry citizens. But despite 60 years of research and billions of dollars, the results to date are also simple: it has not delivered. Read More here
1 December 2016, The Guardian, Obama’s dirty secret: the fossil fuel projects the US littered around the world. Seemingly little connects a community in India plagued by toxic water, a looming air pollution crisis in South Africa and a new fracking boom that is pockmarking Australia. And yet there is a common thread: American taxpayer money. Through the US Export-Import Bank, Barack Obama’s administration has spent nearly $34bn supporting 70 fossil fuel projects around the world, work by Columbia Journalism School’s Energy and Environment Reporting Project and the Guardian has revealed. This unprecedented backing of oil, coal and gas projects is an unexpected footnote to Obama’s own climate change legacy. The president has called global warming “terrifying” and helped broker the world’s first proper agreement to tackle it, yet his administration has poured money into developments that will push the planet even closer to climate disaster. For people living next to US-funded mines and power stations the impacts are even more starkly immediate. Guardian and Columbia reporters have spent time at American-backed projects in India, South Africa and Australia to document the sickness, upheavals and environmental harm that come with huge dirty fuel developments. In India, we heard complaints about coal ash blowing into villages, contaminated water and respiratory and stomach problems, all linked to a project that has had more than $650m in backing from the Obama administration. In South Africa, another huge project is set to exacerbate existing air pollution problems, deforestation and water shortages. And in Australia, an enormous US-backed gas development is linked to a glut of fracking activity that has divided communities and brought a new wave of industrialization next to the cherished Great Barrier Reef. While Obama can claim the US is the world’s leader on climate change – at least until Donald Trump enters the White House – it is also clear that it has become a major funder of fossil fuels that are having a serious impact upon people’s lives. This is the unexpected story of how Obama’s legacy is playing out overseas. Read more here
