14 January 2016, Climate News Network. Science opens routes to energy recycling. From turning carbon dioxide into a fuel to enabling cars to run on water, scientific researchers worldwide are unlocking the potential of new energy sources. Molecular biology has been used by scientists in the US to make a catalyst that can split water into hydrogen and oxygen. It means that a truly renewable biotechnological material could be used to help cars run on water. In China, chemists have announced a nanofabric – a catalyst put together atoms at a time – that could begin the process of turning the greenhouse gas carbon dioxide back into fuel. And with what seems like perfect timing, a new technological venture in Switzerland hopes to be the first commercial plant to harvest carbon dioxide from the air. The first two propositions are still in the laboratory stage, and the third has yet to prove its viability. But the laboratory advances keep alive the hopes of the ultimate in energy recycling. In the first process, water provides the energy for a chemical reaction that propels a vehicle, and then ends up again as water from the exhaust pipe of a car. And in the second, a gas released as emissions from fossil fuel could get turned back into fuel. Read more here

14 January 2016, The Guardian, Climate change disaster is biggest threat to global economy in 2016, say experts. Global warming heads top economists’ concerns for first time but large-scale forced migration seen as most likely risk to materialise. A catastrophe caused by climate change is seen as the biggest potential threat to the global economy in 2016, according to a survey of 750 experts conducted by the World Economic Forum. The annual assessment of risks conducted by the WEF before its annual meeting in Davos on 20-23 January showed that global warming had catapulted its way to the top of the list of concerns. A failure of climate change mitigation and adaptation was seen as likely to have a bigger impact than the spread of weapons of mass destruction, water crises, mass involuntary migration and a severe energy price shock – the first time in the 11 years of the Global Risks report that the environment has been in first place. The report, prepared by the WEF in collaboration with risk specialists Marsh & McLennan and Zurich Insurance Group, comes a month after the deal signed in Paris to reduce carbon emissions. The WEF said evidence was mounting that inter-connections between risks were becoming stronger. It cited links between climate change and involuntary migration or international security, noting that these often had “major and unpredictable impacts”. Espen Barth Eide, the WEF’s head of geopolitical affairs, said there was a risk of Europe fragmenting as a result of “people on the move”. Speaking at a press conference in London to launch the report, Eide said: “I am concerned about the continued support in national politics for keeping Europe together.” Read More here

5 January 2016, YALE Climate connections, Managing Climate Information Overload. After more than 15,000 volunteer hours of development, a climate change expert here describes a sophisticated knowledge-management tool to provide ‘actionable’ climate change information to those most needing it … all of us. Many of us over recent years have become all too familiar with the term “too big to fail.” But what about “too big to follow?” That term applies well to the issue of global climate change, where the daily flood of new and worthwhile information and data can easily swamp even the most sophisticated library database information aficionado. What a waste, what a pity. What if policy makers, legislators, educators, and media just plain engaged citizens were more able to gather and digest the vast volumes of authoritative information on the issue, and make it “actionable”? What if we all were able to find that proverbial needle in the haystack that could lead to informed and cost-effective decision making both individually and globally? A pipe dream? Not so fast. ‘If only we knew what we know …’ The recent release of the Climate Knowledge Brokers Manifesto made clear the challenge of the “too big to follow” situation. We’re engulfed by a cacophony of “climate noise.” As John Naisbitt puts it, “we are drowning in information but starved for knowledge.” It’s far more than an academic or theoretical concern: Climate-related decision-making is becoming much more important throughout broad segments of society, nationally and internationally.

4 January 2015, Washington Post, Here’s how scientific misinformation, such as climate doubt, spreads through social media. Social media is no doubt a powerful force when it comes to the sharing of information and ideas; the problem is that not every article shared on Facebook or Twitter is true. Misinformation, conspiracy theories and rumors abound on the Internet, helping to propagate and support sentiments such as climate doubt and other forms of environmental and scientific skepticism. Figuring out how such ideas diffuse through social media may be key to scientists and science communicators alike as they look for ways to better reach the public and change the minds of those who reject their information. A study published Monday in Proceedings of the National Academy of Sciences sheds new light on the factors that influence the spread of misinformation online. The researchers conclude that the diffusion of content generally takes place within clusters of users known as “echo chambers” — polarized communities that tend to consume the same types of information. For instance, a person who shares a conspiracy theory online is typically connected to a network of other users who also tend to consume and share the same types of conspiracy theories. This structure tends to keep the same ideas circulating within communities of people who already subscribe to them, a phenomenon that both reinforces the worldview within the community and makes members more resistant to information that doesn’t fit with their beliefs.
