12 October 2017, WIRED, The Dirty Secret of the World’s Plan to Avert Climate Disaster. IN 2014 HENRIK Karlsson, a Swedish entrepreneur whose startup was failing, was lying in bed with a bankruptcy notice when the BBC called. The reporter had a scoop: On the eve of releasing a major report, the United Nation’s climate change panel appeared to be touting an untried technology as key to keeping planetary temperatures at safe levels. The technology went by the inelegant acronym BECCS (Bio-Energy with Carbon Capture and Storage), and Karlsson was apparently the only BECCS expert the reporter could find. Karlsson was amazed. The bankruptcy notice was for his BECCS startup, which he’d founded seven years earlier after an idea came to him while watching a late-night television show in Gothenburg, Sweden. The show explored the benefits of capturing carbon dioxide before it was emitted from power plants. It’s the technology behind the much-touted notion of “clean coal,” a way to reduce greenhouse gas emissions and slow down climate change…..But here’s where things get weird. The UN report envisions 116 scenarios in which global temperatures are prevented from rising more than 2°C. In 101 of them, that goal is accomplished by sucking massive amounts of carbon dioxide from the atmosphere—a concept called “negative emissions”—chiefly via BECCS. And in these scenarios to prevent planetary disaster, this would need to happen by midcentury, or even as soon as 2020. Like a pharmaceutical warning label, one footnote warned that such “methods may carry side effects and long-term consequences on a global scale.” …… Still, negative emissions are not mentioned in the Paris Climate Agreement or a part of formal international climate negotiations. As Peters and Geden recently pointed out, no country mentions BECCS in its official plan to cut emissions in line with Paris’s 2°C goal, and only a dozen mention carbon capture and storage. Politicians are decidedly not crafting elaborate BECCS plans, with supply chains spanning continents and carbon accounting spanning decades. So even if negative emissions of any kind turns out to be feasible technically and economically, it’s hard to see how we can achieve it on a global scale in a scant 13 or even three years, as some scenarios require.

28 September 2017, Australian Institute, Climate outliers: Australia and Turkey the only developed nations breaking emissions records. The Australia Institute’s new Climate & Energy Program has released the National Energy Emissions Audit. The Audit, compiled by renowned energy specialist Dr Hugh Saddler, provides a comprehensive, up-to-date indication of key greenhouse gas and energy trends in Australia. “The report finds, disturbingly, that Australia’s annual emissions from energy use have increased to their highest ever level, higher than the previous peak seen eight years ago, in 2009,” Dr Saddler said. “Australia’s failure to invest in efficient transport infrastructure, such as rail, has led to emissions from transport fuels continuing to grow, again, unlike the rest of the developed world. “The continued rise in fuel emissions demonstrates why requiring a reduction for the electricity sector that is only equal to the Paris target would likely see Australia fail to meet its international commitment,” Dr Saddler said. Key findings:
- Australia’s energy emissions continue to increase, breaking all-time record
- Among developed nations, only Australia and Turkey are breaking emissions records
- Petroleum, in particular diesel consumption is the main driver of emission increases
- There is no indication of when or if growth in petroleum emissions will stop Read More here
7 August 2017, New York Times, Scientists Fear Trump Will Dismiss Blunt Climate Report. The average temperature in the United States has risen rapidly and drastically since 1980, and recent decades have been the warmest of the past 1,500 years, according to a sweeping federal climate change report awaiting approval by the Trump administration. The draft report by scientists from 13 federal agencies concludes that Americans are feeling the effects of climate change right now. It directly contradicts claims by President Trump and members of his cabinet who say that the human contribution to climate change is uncertain, and that the ability to predict the effects is limited. “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans,” a draft of the report states. It was uploaded to a nonprofit internet digital library in January but received little attention until it was published by The New York Times. The authors note that thousands of studies, conducted by tens of thousands of scientists, have documented climate changes on land and in the air. “Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change,” they wrote.

4 August 2017, The Conversation, Australia’s greenhouse gas emissions soar in latest figures. Figures reveal trend of increasing emissions since the carbon tax was repealed in 2014 and cast doubt on whether Australia can meet cuts in Paris agreement. Australia’s greenhouse gas emissions are rising to the highest figures seen in years, according to official government figures, increasing 1.6% in the last quarter and 1% in the past year. The country’s emissions in the year to March 2017 are the highest on record at 550.3m tonnes of CO2 equivalent when emissions from land use change are excluded – a sector where the government says its figures have a high degree of uncertainty. The country’s emissions rose by 1.6m tonnes in the quarter to March 2017, or by 1.1% – a figure that is the same whether estimations of land use emissions are taken into account or not. After adjusting for seasonal effects, the department of environment and energy says the rise amounts to a 1.6% rise in the quarter. The rise is particularly striking given emissions almost always drop in the March quarter. The only other March rise was more than a decade ago and by 0.4m tonnes. The figures reveal a clear trend of increasing greenhouse gas emissions since the carbon tax was repealed in 2014 – a trend that runs counter to Australia’s international commitments. Superimposed on promised cuts to emissions made after the Paris climate agreement, Australia appears to be moving further away from being able to meet them – a trend that was predicted by the government’s own projections earlier in the year, which found emissions would continue to rise for decades to come.
