The RFA 2020 Out-In List [科技资讯]

Editor's Note: In keeping with a long-standing RFA holiday tradition, our very own Senior Strategic Advisor offers his views on what is on the way "out" as we turn our calendars to 2020 and what will be "in" as the new year begins. The 2020 Out-In List 2019 was a very challenging year. Most in the ethanol industry will not be sad to see it give way to 2020, in part because there are so many signs of better days ahead. Positive developments with regard to how EPA will implement the RFS going forward and hints of trade battles subsiding have us all seeing the glass half full. So, as I submit this annual "tongue-in-cheek" list of things past and things coming, it is with an Irishman's optimism and a pundit's cynicism ....

Evolution of the Global Carbon Cycle and Climate Regulation on Earth [期刊论文]

Abstract The existence of stabilizing feedbacks within Earth's climate system is generally thought to be necessary for the persistence of liquid water and life. Over the course of Earth's history, Earth's atmospheric composition appears to have adjusted to the gradual increase in solar luminosity, resulting in persistently habitable surface temperatures. With limited exceptions, the Earth system has been observed to recover rapidly from pulsed climatic perturbations. Carbon dioxide (CO2) regulation via negative feedbacks within the coupled global carbon-silica cycles are classically viewed as the main processes giving rise to climate stability on Earth. Here we review the long-term global carbon cycle budget, and how the processes modulating Earth's climate system have evolved over time. Specifically, we focus on the relative roles that shifts in carbon sources and sinks have played in driving long-term changes in atmospheric pCO2. We make the case that marine processes are an important component of the canonical silicate weathering feedback, and have played a much more important role in pCO2 regulation than traditionally imagined. Notably, geochemical evidence indicate that the weathering of marine sediments and off-axis basalt alteration act as major carbon sinks. However, this sink was potentially dampened during Earth's early history when oceans had higher levels of dissolved silicon (Si), iron (Fe), and magnesium (Mg), and instead likely fostered more extensive carbon recycling within the ocean-atmosphere system via reverse weathering—that in turn acted to elevate ocean-atmosphere CO2 levels. Key Points Long term carbon sources and sinks are likely larger than traditional envisioned There is significant silicate weathering in the marine as well as terrestrial settings Ocean oxygenation and evolution of a biotic Si cycle forced a drop in reverse weathering rates and an increase in marine weathering rates

Trudeau will fuel the fires of our climate crisis if he approves Canada’s mega mine Dec 10, 2019 – The Guardian – If the Canadian government approves Teck Resources’ Frontier mine it will “effectively signal Canada’s abandonment of its international climate goals”. The mega mine would add 6 megatonnes of climate pollution every year. That’s on top of the increasing amount of carbon that Canada’s petroleum producers are already pumping out every year. +

Business Vale informs on sale of minority interest 12/27/19 [科技资讯]

Vale informs that it has entered into an agreement to sell the totality of its 25% stake in the Chinese company Henan Longyu Energy Resources to the Yongmei Group, for CNY 1.065 billion, which is equivalent to US$ 152 million, approximately. Longyu operates two coal mines in the province of Henan, producing about 3.4Mtpy of metallurgical and thermal coal. The company is controlled by Yongmei, which is a subsidiary of Henan Energy and Chemical Industry Group. The closing of the deal is expected for the first quarter of 2020, upon completion of conditions precedent to the transfer of the stake. The transaction is in line with Vale's strategy of discipline in capital allocation and business portfolio rationalization.

Climate change contributing to increase in extreme weather events, says expert report [科技资讯]

Heating up: wildfires were one extreme phenomenon that was covered in the report. (Courtesy: Shutterstock/Bruno-Ismael-Silva-Alves) Extreme weather events such as heatwaves, droughts and heavy rainfall are becoming increasingly likely to occur because of human-caused climate change. That is a conclusion of a report by climate experts that was released recently at the annual meeting of the American Geophysical Union in San Francisco. “Explaining extreme events from a climate perspective” is the eighth report in an annual series published by the Bulletin of the American Meteorological Society (BAMS). Comprising 21 peer-reviewed studies of extreme weather around the world in 2018, the report is based on the research of 121 scientists in 13 countries. Since the first report in 2011, BAMS editor-in-chief Jeff Rosenfeld says, “it feels like a century, in terms of how the science has changed.” The papers are now are much more adventurous and look to the future as much as to the past. We study extremes, he said, “because they are the way we experience climate.” This year’s paper covers not only temperature extremes, but floods, hailstorms, wildfires, rainfall, drought, and other phenomena. Stephanie Herring of the US National Oceanic and Atmospheric Administration (NOAA), the lead editor of the series, notes that the report did not attempt to be comprehensive and that some areas of the world, including South America, Africa, and the oceans are undersampled. That said, over the eight years of reports, 168 extreme events have been studied, representing 29 event types. Of those, around 73% involved a role for climate change, while around 27% did not. Over just the past two years, however, around 95% of the events studied involved human-caused climate change. Statistical approach The most common events studied over the eight years, Herring says, were temperature (50 studies) and precipitation or its lack (37 studies). Only in 2016 were scientists able to conclude for the first time that several events were not possible without human influence on climate. No events quite made that list for 2018. The way attributions are made, said Herring, draws on the statistical approach of epidemiologists who compare, for example, lung cancer levels in a group of smokers with that in a similar group of nonsmokers, to determine the increased risk attributable to smoking. Read more Arctic climate continues to concern scientists With regard to climate, we have the observable record of, for example, rainfall in a certain region over a certain period of time. But, Herring says, we have no “planet B” to use as a control study. Therefore, a modelled planet B is created, with atmospheric data based on 1850, prior to the start of the industrial revolution. By comparing observed inputs for our real planet with simulated inputs for planet B, scientists come up with a fraction of attributable risk, the likelihood that the event was contributed to by anthropogenic climate change. The reason that more and more papers in the annual reports are finding a role for climate change could be that scientists now have improved observational tools and models, allowing them to better detect the signal in the noise, Herring says. But, also, it may be that the role of climate change has become a more significant driver of events in recent years. Want to read more?
