    New electrocatalyst converts CO2 into ethanol, acetone, and n-butanol with high efficiency - Green Car Congress
    https://www.greencarcongress.com/2021/11/20211116-electrocat.html

    The electrocatalytic conversion of CO2 using renewable energy could establish a climate-neutral, artificial carbon cycle. Excess energy produced by photovoltaics and wind energy could be stored through the electrocatalytic production of fuels from CO2. These could then be burned as needed. Conversion into liquid fuels would be advantageous because they have high energy density and are safe to store and transport.

    Now, researchers in China have developed a new electrocatalyst that yields ethanol, acetone, and n-butanol as major products with a total C2-4 faradaic efficiency of about 49 % at −0.8 V vs. reversible hydrogen electrode (RHE), which can be maintained for at least 3 months. A paper on the development is published in the journal Angewandte Chemie.

    Wildfires are erasing Western forests. Climate change is making it permanent. | Grist
    https://grist.org/climate/climate-change-forest-loss/

    Now that the winter has cooled the 2021 fire season, scientists are looking at the big burn scars across the West with the grim understanding that, in some places, the pine and Douglas fir forests will not return. 

    The driving force here is that the rising global temperature is wiping out seedlings. In many spots around the U.S. West, summer temperatures are already high enough to cook young trees before they can develop thick protective bark. Others have become so dry that seedlings shrivel before their roots can grow deep enough to reach groundwater. Both circumstances can thwart forest regeneration. Mature trees can survive in these areas long after they stop reproducing. But when fires wipe out these forests and seedings can’t get a foothold, they are replaced with grasses and dense brush. 

    Climate change has already shifted biomes. Intense fires simply clear away the last vestiges of the old regime.

    Pesticides 'cost double the amount they yield', study finds
    https://euobserver.com/climate/153671

    According to a study published on Tuesday (30 November), the cost of pesticides may far outweigh the economic benefits.

    The Bureau for the Appraisal of Social Impacts for Citizen Information (BASIC), a Paris-based NGO, found pesticide producers cost the EU €2.3bn in subsidies.

    At the same time, the sector makes about €900m in profits, and the study argues this is not an efficient way of spending agricultural funds.

    "Tripling organic farms by 2030 would cost €1.85bn per year - less than the annual subsidies being spent on pesticides," a group of researchers connected to BASIC wrote.

    Future climate change shaped by inter-model differences in Atlantic meridional overturning circulation response | Nature Communications
    https://www.nature.com/articles/s41467-021-24015-w

    In climate model simulations of future climate change, the Atlantic Meridional Overturning Circulation (AMOC) is projected to decline. However, the impacts of this decline, relative to other changes, remain to be identified. Here we address this problem by analyzing 30 idealized abrupt-4xCO2 climate model simulations. We find that in models with larger AMOC decline, there is a minimum warming in the North Atlantic, a southward displacement of the Inter-tropical Convergence Zone, and a poleward shift of the mid-latitude jet. The changes in the models with smaller AMOC decline are drastically different: there is a relatively larger warming in the North Atlantic, the precipitation response exhibits a wet-get-wetter, dry-get-drier pattern, and there are smaller displacements of the mid-latitude jet. Our study indicates that the AMOC is a major source of inter-model uncertainty, and continued observational efforts are needed to constrain the AMOC response in future climate change.

    1 Billion People At Risk From Potentially Lethal Heat If Global Warming Passes 2C, Scientists Warn

    The recent expansion of Atlantic waters into the Arctic Ocean represents undisputable evidence of the rapid changes occurring in this region. Understanding the past variability of this “Atlantification” is thus crucial in providing a longer perspective on the modern Arctic changes. Here, we reconstruct the history of Atlantification along the eastern Fram Strait during the past 800 years using precisely dated paleoceanographic records based on organic biomarkers and benthic foraminiferal data. Our results show rapid changes in water mass properties that commenced in the early 20th century—several decades before the documented Atlantification by instrumental records. Comparison with regional records suggests a poleward expansion of subtropical waters since the end of the Little Ice Age in response to a rapid hydrographic reorganization in the North Atlantic. Understanding of this mechanism will require further investigations using climate model simulations.

    Vybijeme chovy. Na každém praseti tratíme tisíc korun, tvrdí chovatelé - Seznam Zprávy
    https://www.seznamzpravy.cz/clanek/ekonomika-firmy-vybijeme-chovy-na-kazdem-kilogramu-tratime-tisic-korun-tvrdi-chovatele-182099

    Říká se, že zemědělci neustále brečí. Situace je ale vážná. Vysloveně zvažujeme, že budeme zavírat některé chovy brojlerů i prasat. Není možné, abychom takto dál fungovali,“ uvedl Zdeněk Mlázovský, místopředseda představenstva společnosti Proagro Nymburk, která se zabývá rostlinnou produkcí a chovem drůbeže, jatečných prasat a nosnic.

    „Potřebovali bychom prodávat vejce o 20 až 30 haléřů dráž, brojlery až o osm korun a skoro se to bojím říct, ale vepřové až o 15 korun dráž,“ dodal.

    Podle něj je sice dlouhodobě složité promítnout výrobní náklady do prodejních cen živočišných produktů, ale v poslední době je situace neudržitelná. „Je to extrém, není už úplně možné, abychom dokázali náklady snížit a dostali se do plusových čísel,“ upozornil.

    Za pohonné hmoty podnik platí až o 30 procent víc, za krmiva desítky procent, obaly o sedm procent a za elektřinu a plyn, které prodražují chovy kuřat, jimž se musí zatápět, troj- až čtyřnásobek

    Why the oil industry's pivot to carbon capture and storage – while it keeps on drilling – isn't a climate change solution
    https://theconversation.com/why-the-oil-industrys-pivot-to-carbon-capture-and-storage-while-it-keeps-on-drilling-isnt-a-climate-change-solution-171791

    Seven large-scale CCS projects have been attempted at U.S. power plants, each with hundreds of millions of dollars of government subsidies, but these projects were either canceled before they reached commercial operation or were shuttered after they started due to financial or mechanical troubles. There is only one commercial-scale CCS power plant operation in the world, in Canada, and its captured carbon dioxide is used to extract more oil from wells – a process called “enhanced oil recovery.”

    In industrial facilities, all but one of the dozen CCS projects in the U.S uses the captured carbon dioxide for enhanced oil recovery.

    This expensive oil extraction technique has been described as “climate mitigation” because the oil companies are now using carbon dioxide. But a modeling study of the full life cycle of this process at coal-fired power plants found it puts 3.7 to 4.7 times as much carbon dioxide into the air as it removes.
    ...
    A National Academies of Sciences study of direct air capture’s energy use indicates that to capture 1 gigaton of carbon dioxide per year, this type of direct air capture system could require up to 3,889 terawatt-hours of energy – almost as much as the total electricity generated in the U.S. in 2020. The largest direct air capture plant being developed in the U.S. right now uses this system, and the captured carbon dioxide will be used for oil recovery.
