    A first look at US cement manufacturers' road map to carbon neutrality - Electrek
    https://electrek.co/.../03/10/a-first-look-at-us-cement-manufacturers-road-map-to-carbon-neutrality/

    Electrek spoke with Rick Bohan, VP of sustainability at the Portland Cement Association (PCA). The Portland Cement Association represents 92% of US cement manufacturing production capacity and has distribution facilities in every continental US state. Cement is the second-most-used construction material on the planet.

    In November 2020, PCA announced an industry-wide ambition to develop a road map by the end of 2021 to help its member companies achieve carbon neutrality across the concrete value chain by 2050.

    ...

    Increasing access to alternative fuels, especially materials that otherwise end up in landfills, for cement plants to use;

    Rapidly driving the adoption of innovative products like Portland limestone cements (PLC), performance-based concrete mixtures, blended cements and more;

    Investing in carbon capture, utilization, and storage (CCUS) technology and critical infrastructure to support CCUS, including a robust and smart electric grid.

    TADEAS: vysledky pekne, kvalitu zdroje nedokazu overit. kazdopadne me to privadi k myslenkam,
    ze doomsday framing klimaticke otazky je mozna zbytecne dramaticky a presne v duchu dnes tak oblibeneho panic-capitalismu. v praxi jde mozna “jen” o přeháňku zprůmyšlnění a privatizace skoro všeho. dyť je to “jen” takova rakovina, virus co casem vychcipe. a my s nim. mno beztak bysme (chcipli taky). užíváme si to pekně a co se dá, zachraňujem/kurvíme (nehodící se škrtněte) pro naše děti.

    Defining and validating regenerative farm systems... | F1000Research
    https://f1000research.com/articles/10-115/v1

    Regenerative outcomes were strongly correlated with our approach to farm scoring. Soil organic matter, fine particulate organic matter, total soil carbon, total soil nitrogen, phosphorous, calcium and sulfur all increased alongside regenerative matrix scores in one or both of the cropping systems. Water infiltration rates were significantly faster in more regenerative almond orchards. Soil bacterial biomass and Haney soil health test scores were higher as cropland incorporated more regenerative practices. Plant species diversity and biomass increased significantly with the number of regenerative practices employed on almonds and rangelands. Invertebrate species diversity and richness were positively associated with regenerative practices in corn, almonds, and rangelands, whereas pest populations and almond yields were unaffected by the number of regenerative practices. Corn yields were negatively associated with more regenerative practices, while almond yields were unaffected by the number of regenerative practices. Profit was significantly higher on more regenerative corn and almond operations.

    Bill Gates Sounds Alarm On Bitcoin's Energy Consumption–Here's Why Crypto Is Bad For Climate Change
    https://www.forbes.com/...ciano/2021/03/09/bill-gates-bitcoin-crypto-climate-change/?sh=427574206822

    "Bitcoin uses more electricity per transaction than any other method known to mankind,” Gates told the New York Times in a recent interview, calling himself a "bitcoin skeptic," and adding that "it’s not a great climate thing.”

    To Gates' point, Alex de Vries, a data scientist at the Dutch Central Bank, estimates that each bitcoin transaction requires an average 300 kg of carbon dioxide (CO2)–equivalent to the carbon footprint produced by roughly 750,000 Visa swipes.

    Scholars believe that the coke reductant within the blast furnace can be replaced by hydrogen, which results in the only emission being water throughout the process that will not lead to any pollution. Hydrogen can also provide electricity for electric arc furnaces, which makes it more possible for a relatively cleaner steelmaking industry to happen. How is the feasibility? Mitsubishi Heavy Industries will be establishing steelmaking equipment that replace coal with hydrogen in Europe, and is currently working with major Austrian steel businesses on developing verification equipment, with operation initiating in 2021 at the earliest.

    Emerging Swedish business H2 Green Steel (H2GS) will also appropriate US$3 billion for steel refining using the hydrogen produced by the renewable energy equipment in Boden-Luleå, and plans to commence production in 2024. H2GS is expected to produce 5 million tons of steel with zero-carbon emission steel by 2030.

    DWD: Zwei-Grad-Ziel nicht mehr zu halten | MDR.DE
    https://www.mdr.de/nachrichten/panorama/dwd-warnt-vor-drastischem-temperatur-anstieg-100.html

    The German Weather Service (DWD) is sounding the alarm: According to the organization, it will no longer be possible to limit global warming to two degrees Celsius by the end of the century. The international community set the two-degree target in the 2015 Paris Climate Agreement . DWD President Gerhard Adrian said at a digital press conference on climate research in Offenbach: "Unfortunately, at the moment it even looks like a plus of three to four degrees." The two-degree target will be missed.

    TADEAS: to se asi "brzo" dozvime

    An international team of oceanographers aboard the Russian research vessel Akademik Keldysh has confirmed a large-scale, ongoing release of methane from the seabed on the East Siberian Arctic Shelf.
    The gas is believed to be released by the melting of subsea permafrost, which in turn allows the release of methane gas from previously-stable methane hydrates. The seabed of the East Siberian Arctic Shelf is unique in that large swaths contain permafrost layers built up some 20-30,000 years ago, when the area was dry land and sea levels were far lower.

    "The discovery of actively releasing shelf slope hydrates is very important and unknown until now,” chief scientist Igor Semiletov told the paper.

    Their results have not yet been peer-reviewed or published, but they represent an extension of previous observations of methane seeps in the same area. In voyages to the region in years past, Semiletov's team has discovered large craters on the seabed emitting significant quantities of methane.

    Methane Emissions Continue to Rise
    https://earthobservatory.nasa.gov/images/146978/methane-emissions-continue-to-rise

    Across the study years, wetlands contributed 30 percent of global methane emissions, with oil, gas, and coal activities accounting for 20 percent. Agriculture, including enteric fermentation and manure management, made up 24 percent of emissions, and landfills comprised 11 percent. Sixty-four percent of emissions came from tropical regions of South America, Asia, and Africa, with temperate regions accounting for 32 percent and the Arctic contributing 4 percent.

    ...

    High-latitude ecosystems are particularly vulnerable to climate change. Large amounts of carbon are stored in frozen soils (permafrost) and in forest vegetation in the Arctic. As it thaws, water-logged soil becomes an ideal environment for methane production. “However, we have yet to detect abnormal methane emissions in higher-latitude regions,” said Poulter, “despite thawing permafrost and record-breaking air temperatures year-after-year.”
