15 November 2016, Energy Post, Biofuels turn out to be a climate mistake. Biofuels are usually regarded as inherently carbon-neutral, but once all emissions associated with growing feedstock crops and manufacturing biofuel are factored in, they actually increase CO2 emissions rather than reducing them, writes John DeCicco of the University of Michigan. According to DeCicco, biofuels are actually more harmful to the climate than gasoline. Ever since the 1973 oil embargo, U.S. energy policy has sought to replace petroleum-based transportation fuels with alternatives. One prominent option is using biofuels, such as ethanol in place of gasoline and biodiesel instead of ordinary diesel. Transportation generates one-fourth of U.S. greenhouse gas emissions, so addressing this sector’s impact is crucial for climate protection. Many scientists view biofuels as inherently carbon-neutral: they assume the carbon dioxide (CO2) plants absorb from the air as they grow completely offsets, or “neutralizes,” the CO2 emitted when fuels made from plants burn. Many years of computer modeling based on this assumption, including work supported by the U.S. Department of Energy, concluded that using biofuels to replace gasoline significantly reduced CO2 emissions from transportation.Biofuels are far from inherently carbon-neutral Our new study takes a fresh look at this question. We examined crop data to evaluate whether enough CO2 was absorbed on farmland to balance out the CO2 emitted when biofuels are burned. It turns out that once all the emissions associated with growing feedstock crops and manufacturing biofuel are factored in, biofuels actually increase CO2 emissions rather than reducing them.

15 November 2016, DESMOG, Meet the Fossil Fuel Lobbyists and Climate Science Deniers at the Marrakech COP22 Talks. It’s no secret fossil fuel companies will have to fundamentally change their business models if countries are serious about tackling climate change. With so much skin in the game, it’s no surprise they find ways to try and influence climate policy at the highest level. The international climate talks in Marrakech this week has provided the perfect opportunity for corporate lobbyists and climate science deniers to push their high carbon agendas. Who’s who Prior to the COP22 negotiations currently underway in Marrakech, Corporate Accountability International released a mapshowing how fossil fuel representatives can get access at the highest level. Many of the groups they identify do indeed have a presence in the inner ‘blue zone’ of the talks, where negotiators meet to hammer out the details of global climate policy. (Most non-state actors and companies are officially consigned to the ‘green zone’ in a separate section of the venue). Read More here
15 November 2016, Scientific American, Military Leaders Urge Trump to See Climate as a Security Threat. It may well end up in the paper shredder, but a bipartisan group of defense experts and former military leaders sent Donald Trump’s transition team a briefing book urging the president-elect to consider climate change as a grave threat to national security. The Center for Climate & Security in its briefing book argues that climate change presents a risk to U.S. national security and international security, and that the United States should advance a comprehensive policy for addressing the risk. The recommendations, released earlier this year, were developed by the Climate and Security Advisory Group, a voluntary, nonpartisan group of 43 U.S.-based senior military, national security, homeland security and intelligence experts, including the former commanders of the U.S. Pacific and Central commands. The briefing book argues that climate change presents a significant and direct risk to U.S. military readiness, operations and strategy, and military leaders say it should transcend politics. It goes beyond protecting military bases from sea-level rise, the military advisers say. They urge Trump to order the Pentagon to game out catastrophic climate scenarios, track trends in climate impacts and collaborate with civilian communities. Stresses from climate change can increase the likelihood of international or civil conflict, state failure, mass migration and instability in strategically significant areas around the world, the defense experts argue.

14 November 2016, The Conversation, Fossil fuel emissions have stalled: Global Carbon Budget 2016. For the third year in a row, global carbon dioxide emissions from fossil fuels and industry have barely grown, while the global economy has continued to grow strongly. This level of decoupling of carbon emissions from global economic growth is unprecedented. Global CO₂ emissions from the combustion of fossil fuels and industry (including cement production) were 36.3 billion tonnes in 2015, the same as in 2014, and are projected to rise by only 0.2% in 2016 to reach 36.4 billion tonnes. This is a remarkable departure from emissions growth rates of 2.3% for the previous decade, and more than 3% during the 2000’s. Given this good news, we have an extraordinary opportunity to extend the changes that have driven the slowdown and spark the great decline in emissions needed to stabilise the world’s climate. This result is part of the annual carbon assessment released today by the Global Carbon Project, a global consortium of scientists and think tanks under the umbrella of Future Earth and sponsored by institutions from around the world.
