21 January 2016, Reuters, U.S. appeals court declines to block Obama carbon emissions plan. In a big victory for the Obama administration, a U.S. federal court on Thursday rejected a bid by 27 states to block its Clean Power Plan, the centerpiece of its strategy to combat climate change by reducing carbon emissions from power plants. A three-judge panel of the U.S. Court of Appeals for the District of Columbia Circuit issued a brief order denying an application seeking to stay the rule while litigation continues. The states, led by West Virginia, and several major business groups in October launched the legal challenges seeking to block the Obama administration’s proposal to curb carbon dioxide emissions from power plants. More than a dozen other states and the National League of Cities, which represents more than 19,000 U.S. cities, filed court papers backing the Environmental Protection Agency’s rule. The rule aims to lower carbon emissions from the country’s power plants by 2030 to 32 percent below 2005 levels. It is the main tool for the United States to meet the emissions reduction target it pledged at U.N. climate talks in Paris last month. For President Barack Obama, executing his climate change strategy would be a legacy-defining accomplishment. “We are confident that the plan will reduce carbon pollution and deliver better air quality, improved public health, and jobs across the country,” the White House said in a statement on Thursday. The court action means the regulation remains in place but it is not the final word in the legal fight. The appeals court still has to hear oral arguments on June 2 and decide whether the regulation is lawful. Read More here

21 January 2016, Climate News Network, Carbon capture plans need urgent aid. Call for governments to give financial backing for technology that could help save the world from overheating by preventing CO2 escaping into the atmosphere. Governments may no longer be investing in the capture of carbon dioxide in the atmosphere. But a new study says that doesn’t mean it’s a bad idea. It argues that the world just needs to think harder and spend more to make the technology work because, to contain climate change, it may prove the only realistic and affordable way to dramatically reduce carbon emissions. Many governments appear to agree, and include carbon capture and storage in their plans to keep the world from dangerous climate change, But, at the same time, many are abandoning many trials that are needed to make it work. David Reiner, senior lecturer in technology policy at the University of Cambridge Judge Business School, argues in the new journal Nature Energy that stopping trials is foolish. Effective answer In a world addicted to fossil fuel energy, but threatened with catastrophic climate change driven by the greenhouse gas emissions from those same fossil fuels, he says that one effective answer would be to capture the carbon dioxide before it gets into the atmosphere, and then store it. He writes that the only way to find out how to do this is to spend billions on a range of possible attempts at carbon capture and storage (CCS), and then choose the best one. “If we are serious about meeting aggressive national or global emissions, the only way to do it affordably is with CCS,” Dr Reiner says. “But, since 2008, we have seen a decline in interest in CCS, which has essentially been in lock step with our declining interest in doing anything serious about climate change.” Just before the UN climate change summit in Paris last December, the UK government cancelled a £1 billion competition to support large-scale demonstration projects. Since 2008, other projects have been cancelled in the US, Canada, Australia and Europe. Read More here
20 January 2016, Science Daily, Impact of human activity on local climate mapped. Earth’s temperature has increased by 1°C over the past century, and most of this warming has been caused by carbon dioxide emissions. But what does that mean locally? A new study published in Nature Climate Change pinpoints the temperature increases caused by CO2 emissions in different regions around the world. Using simulation results from 12 global climate models, Damon Matthews, a professor in Concordia’s Department of Geography, Planning and Environment, along with post-doctoral researcher Martin Leduc, produced a map that shows how the climate changes in response to cumulative carbon emissions around the world. They found that temperature increases in most parts of the world respond linearly to cumulative emissions. “This provides a simple and powerful link between total global emissions of carbon dioxide and local climate warming,” says Matthews. “This approach can be used to show how much human emissions are to blame for local changes.” Read More here
19 January 2016, Science Daily, One-stop shop for biofuels. First high-gravity one-pot process for producing cellulosic ethanol developed. The falling price of gasoline at the pumps may warm the hearts of consumers but it chills the souls of scientists who recognize that humankind must curtail the burning of fossil fuels to reduce the threat of climate change. Biofuels can help mitigate climate change and provide us with a sustainable source of transportation energy if yields and production costs are economically competitive. A major step towards achieving this goal has been achieved by researchers with the U.S. Department of Energy (DOE)’s Joint BioEnergy Institute (JBEI). Led by Seema Singh and Blake Simmons, JBEI researchers have developed a “high-gravity” one-pot process for producing ethanol from cellulosic biomass that gives unprecedented yields while minimizing water use and waste disposal. The process utilizes a combination of ionic liquid pretreatment, enzymatic saccharification, and yeast fermentation for the production of concentrated fermentable sugars that result in high-titer cellulosic ethanol. “High gravity” means high biomass loading — the higher the biomass loading, the lower the costs for converting it to fuels.
