26 October 2016, Bloomberg, Magical Thinking Won’t Stop Climate Change. World leaders have started to generate some real optimism with their efforts to address global climate change. What’s troubling, though, is how far we remain from getting carbon emissions under control — and how much wishful thinking is still required to believe we can do so. The Paris agreement on climate change has garnered the national signatories needed to go into force on Nov. 4. Some economists see it as a promising framework for cooperation among many different countries, especially if those not pulling their weight suffer penalties such as trade sanctions. There’s even talk of aiming for the more ambitious goal of keeping global temperatures within 1.5 degrees Celsius or less of their pre-industrial level, as opposed to the currently agreed 2 degrees. Meanwhile, another major international deal has been reached to phase out greenhouse gases used in refrigeration systems, and solar energy technology continues its rapid advance. For all the progress, though, the gap between what needs to happen and what is happening remains large. Worse, it’s growing. Consider, for example, how far the planet remains from any of the carbon emission trajectories in which — according to the Intergovernmental Panel on Climate Change — global warming would remain below 2 degrees. Even in the most lenient scenarios, we would have to be cutting net emissions already. Yet under the pledges countries have made in the Paris framework, emissions will keep increasing sharply through at least 2030, as this chart from a recent commentary in the journal Science illustrates….. The gap is probably even bigger than the chart suggests. As climate scientists Kevin Anderson and Glen Peters argue, an element of magical thinking has crept into the IPCC projections. Specifically, they rely heavily on the assumption that new technologies will allow humans to start sucking carbon out of the atmosphere on a grand scale, resulting in large net negative emissions sometime in the second half of this century. This might happen, but we don’t know how to do it yet. The assumptions about negative emissions amount to a bizarre step in what ought to be a cautious and conservative analysis. The IPCC scenarios essentially ignore the vast uncertainty surrounding a technology that does not yet exist, and about our ability to ramp it up to the required scale. To eliminate that much atmospheric carbon, as geophysicist Andrew Skuce estimates, we would need an industry roughly three times as big as the entire current fossil fuel industry — and we would need to create it fast, building something like one new large plant to capture and store carbon every day for the next 70 years. Does that sound likely? Read More here

17 October 2016, Renew Economy, Historic climate deal reached on potent refrigerant gases. After almost a decade of efforts to achieve a climate benefit of up to 0.5°C reduction in global temperature by the end of the century, 197 nations have finally reached agreement on the Kigali Amendment to the Montreal Protocol. At the conclusion of unprecedented overnight negotiations extending past 7am last Saturday in the Rwandan capital, a face-saving compromise was finally achieved. Negotiations at the Montreal Protocol on an amendment to include the hydrofluorocarbons or HFCs, potent synthetic greenhouse gases used primarily as refrigerants, began in earnest in 2009. But the first concerted efforts to draw international attention to the problem of projected rapid growth in HFC emissions began at the UNFCCC COP13 in Bali in 2007, where the London and Washington based Environmental Investigation Agency worked for two weeks with several large boxes of briefing notes to teach observers and negotiators alike to speak about the “F for Forgotten” F-gases.Highly regarded scientific papers by the Dutch climate scientist Guus Velders (et. al.) in the Proceedings of the National Academy of Sciences (PNAS) in 2007 and 2009 were crucial in gaining the attention of the highest levels of the Obama administration, and so the long road to the historic agreement in Kigali last week began. As Obama’s Presidential statement on the agreement concludes, “diplomacy is never easy”. In spite of its flaws and shortcomings, the compromise brokered to deliver the climate legacy sought by the US is a significant achievement. Jubilation that might have been expected by the achievement of the “largest temperature reduction ever achieved by a single agreement” (according to one seasoned observer) has been tempered by delays in implementation of restrictions on use of HFCs granted to a block of recalcitrant developing countries including India, Pakistan, Iran, Iraq and Arab Gulf states.

20 October 2016, Climate Home, UN approves plans for new IPCC global warming report. Governments have approved plans for a new UN report to explore the impacts of warming of 1.5C above pre-industrial levels at a meeting in Bangkok, Thailand. The head of the Intergovernmental Panel on Climate Change (IPCC) Hoesung Lee said the study will be delivered by 2018 ahead of a global review into efforts to tackle climate change. An outline of the study released on Thursday revealed the IPCC will explore development pathways compatible with limiting warming to 1.5C and their economic implications. Scientists will also examine the global and regional changes that can be expected under warming up to and above 1.5C. So far, the world has heated to around 1C above 1850 levels…. In contrast with previous IPCC publications this will be “succinct and objective to provide policymakers with guidance to act,” she added. Still, some commentators noted that a draft plan for the report approved by scientists had been watered down after the Bangkok meeting, specifically areas focused on strengthening global efforts to tackle climate change. “The material that was removed relates to increasing ambition, policy, institutions,” said Glen Peters, a senior researcher at Oslo-based CICERO. “These are all the areas that are critical to understand if we want to get to 1.5C, but also the areas the governments seemingly want to keep off limits.” Read More here
17 October 2016, Climate Home, Rich nations on course to miss 2020 climate finance goal. The world’s richest countries are on course to miss a target to mobilise US$100 billion of climate funds a year by 2020, a new report by the UK and Australian governments has revealed. It forecasts a total of $93 billion a year will be delivered by the end of the decade to help poorer nations invest in green energy and prepare for future climate change impacts. The 27-page report, released on Monday, says that figure could soar to a best-case scenario of $133 billion if public funds start to leverage more private sector support in the coming years. “The projection should be considered a conservative, indicative aggregation of public climate finance levels in 2020, rather than a firm prediction,” say the governments. The figures are based on analysis of global climate finance flows by the Paris-based Organisation for Economic Co-operation and Development (OECD). It comes just under a month before the UN’s major climate summit of 2016 opens for business in Marrakech, Morocco, with finance high on the agenda. Last week, UN climate chief Patricia Espinosa urged the world’s rich nations to come prepared with a plan to make good their 2009 promise to deliver $100 billion a year by 2020. While small compared to the $286 billion renewables investments through 2015, the $100 billion number is seen as a barometer for the commitment of wealthy governments to meet their promises. Under the OECD’s new projections, funding solely from governments including the US and EU-28 and development banks will tip $67 billion by 2020, up from $41bn in 2014. It then adds the amount of green finance from banks, funds and pensions that this could unlock, leading to a final figure closer to $100 billion. Read More here
