    BP imposes hiring freeze and halts new offshore wind projects | BP | The Guardian
    https://amp.theguardian.com/business/article/2024/jun/27/bp-imposes-hiring-freeze-and-halts-new-offshore-wind-projects

    New boss Murray Auchincloss reverses move away from fossil fuels, which had weighed on company’s share price

    The head of BP has imposed a hiring freeze and halted new offshore wind projects, in an apparent attempt to placate investors who are unhappy with the oil company’s green targets.
    ...
    Looney, who had committed BP to some of the industry’s greenest climate goals, was ousted last September for failing to disclose relationships with colleagues.

    The decision to slow BP’s green ambitions has stoked concerns that Looney’s plan to move the company away from fossil fuels, with a pledge to “become a net zero company by 2050 or sooner”, may soon be derailed.

    BP has come under pressure from shareholders over its green targets because some renewable projects have proved more costly than expected, and profits from oil and gas have soared after Russia’s invasion of Ukraine more than two years ago.

    In response, the company set out plans earlier this year to cut oil and gas production by just 25% between 2019 and 2030 – well short of its previous target of a 40% reduction over the same timeframe.
    ...
    Earlier this month BP’s rival Shell set out its own plans to scale back its green growth ambitions, reducing the number of staff working on low-carbon solutions by about 200 roles while shifting the focus towards high-profit oil projects and expanding its gas business.

    SHEFIK: Biden má demenci, ví se to minimálně rok. Demokrati ale jeli linku že to jsou pomluvy protistrany. Dnes v noci měli debate a náhle to ví všichni (catastrophic outcome). Národ má šok. Z nějakého mi nepochopitelného důvodu nemají náhradního kandidáta a už je málo času do voleb.

    YMLADRIS: Škoda že US vynalezlo demokracii aby se dala mírově předávat moc, ale že by se mírově vyměnil running prezident když má Alzheimera, to je nemožné.

    LOL:

    Former President Donald Trump has indicated that he would seek to dismantle President Biden's climate programs if re-elected. Trump has repeatedly criticized Biden’s climate policies, particularly the Inflation Reduction Act (IRA), which he has vowed to repeal. The IRA includes various provisions aimed at reducing carbon emissions, such as tax credits for electric vehicles and renewable energy projects, and incentives for improving energy efficiency in homes and businesses.

    Trump's plan involves a significant rollback of these measures, including halting new regulations on greenhouse gas emissions, ending subsidies for renewable energy, and promoting increased drilling for oil and gas. He aims to restore what he terms "energy dominance" by expanding fossil fuel production and reducing the regulatory burden on energy companies. This approach is expected to increase U.S. carbon emissions significantly, potentially adding an extra 4 billion tonnes of emissions by 2030 compared to Biden's policies (MIT Technology Review) (Home) (Mother Jones) (Carbon Brief).

    Furthermore, Trump’s agenda includes dismantling various climate-focused offices and programs within federal agencies, reducing the size and influence of the Environmental Protection Agency (EPA), and removing the U.S. from the Paris Agreement again (Home) (Mother Jones).

    These proposed changes have raised concerns among climate scientists and advocates, who warn that such actions could have dire consequences for both national and global efforts to combat climate change. The rollback of Biden’s climate initiatives could slow down the transition to cleaner energy sources and undermine international climate commitments (Home) (Mother Jones) (Carbon Brief).

    YMLADRIS: Mnohé z těchto odvětví AI (i když se tomu tak dříve neříkalo) používají už dlouho, ale jo těch pár dobrých využití se dá najít, třeba to skládání proteinů by byl obrovský pokrok. Nicméně je pro to potřeba tvořit obrovské LLM, aby to každý měl v mobilu, zaplavily se tím sociální sítě,.. což není potíž technologie, ale jako v mnoha dalších případech - náš.

    ERGOSUM: Jedná se hlavně o SO2, je ve všech fosilních palivech, také způsobuje (společně s NO2) kyselé deště.
    Pro běžný transport se používá odsiřené palivo (používá se na to 30% světové produkce vodíku), ale např. v lodním průmyslu se stále používá tzv. HFO - heavy fuel oil, lodě na něj plujou a je znatelně levnější.

    Jak už ti tu psali, "Global dimming", já bych opravil, pokud někdo nemá aktuálnější data, že lidskou činností maskujeme v rozsahu 0.5-1.5C, přesné číslo nemáme, pokud se něco po letošních zkušenostech nezměnilo.

    Možná jsi slyšel o rekordních teplotách v Severním atlantickém oceánu, z části se to přičítá regulaci paliva v lodní dopravě, která mimochodem má smysl.

    Zrtrátu tohoto maskování za pomoci fosilních paliv pocítime dříve či později, ale určitě roste diskuze ohledně cloud-seedingu a dalších možnostech jak alespoň krátkodobě oteplení snížit. Otázkou jsou nežádané efekty, enegetická a technologická náročnost, a další, ale cokoliv pro prodloužení BAU, I guess.

    ERGOSUM: to se tu celkem řeší už déle. Můj postoj je že se bude střílet sira, geoinzenyring. Je to mnohem levnější než dekarbonizace, tak jak to asi dopadne. Když kurzgesagt má video Geoengineering na YT kde je rozebráno v celé děsivosti

    Jinak zvyšování teploty protože jsou ekologičtější lodě, elektrárny, .. ano. Můžeš googlit global dimming, mělo to zamaskovat půl stupně, teď se to odmaskovava

    Narazil jsem na článek, podle kterého lze snížit zahřívání planety vyšší odrazivostí mraků.
    Například přidáním prachových částic a aerosolů.

    Pak mě ovšem napadlo, že jestli tomu tak je, může být příčinou oteplování i snížení smogu. A tedy naše snaha o čistčí životní prostředí.

    Budeme tedy kromě snižování CO2 vracet i popílek?

    Fostering Effective Energy Transition 2024
    https://www.weforum.org/publications/fostering-effective-energy-transition-2024/

    In the 14th edition of the Fostering Effective Energy Transition report, the WEF noted that its benchmarks for 107 of the 120 countries surveyed indicated they had made advances in their transitions towards clean and sustainable energy systems over the last decade.

    But it said that the slowdown in the pace of the global energy transition, first identified in its 2022 data, had intensified in the past year. The survey found that more than 80% of countries had moved backwards compared to the previous report in at least one of the three main energy system performance dimensions it benchmarks, namely security, equity (meaning equitable energy distribution, access and cost) and sustainability.

    ...

    the WEF reports that the gap in overall scores has narrowed between advanced and developing economies and says that the “centre of gravity” of the transition is shifting towards developing countries. Nevertheless, developed countries and China have attracted almost 90% of the growth in clean energy investment since 2021.

    YMLADRIS: Všechny ty jmenovaný věci jsou daleko komplexnější než že "někam dáme gen" a bude to v pohodě.. Samozřejmě to pomůže, ale ty implikace jsou asi jako psát po vynálezu vrtule - budeme mít lítací města, auta a kola..

    kdyztak at mi to uz TUHO smaze jako off topic, ale jeste priklad k tomu AI potencialu. je na svete nova stavebnice, geneticka, s potencialem. Kdby se to napojilo na nejake ML, ktere fakt dokaze uvazovat a delat research, tak... (optimalizace managementu nasich ekosystemu and whatnot, rychle).

    The implications of this are staggering. Here are just a few possibilities:

    • Gene Therapy 2.0: Current gene therapy approaches often rely on somewhat random insertion of therapeutic genes. With bridge recombination, we could insert corrective genes exactly where they need to go, without risking disruption of other important genes.

    • Synthetic Biology: Want to give an organism a completely new capability? Just design the gene and insert it precisely where you want it.

    • Evolutionary Biology: We could insert reporter genes at specific locations across the genome, allowing us to watch evolution happen in real time.

    • Agricultural Improvements: We could insert beneficial genes into crops with unprecedented precision, potentially revolutionizing our ability to create drought-resistant or nutrient-enhanced plants.

    • Bioengineering: Imagine being able to design and build entire genetic circuits, inserting each component exactly where it needs to be for optimal function.

    Friends,

    This new paper presents an excellent summary of many of the present misunderstandings concerning soil carbon drawdown.

    How farming could become the ultimate climate-change tool
    Nogrady 2024
    https://www.nature.com/articles/d41586-024-02036-x


    Contrary to what is claimed in this paper:

    The production and release of root exudates — not, as often mistakenly believed, plant decomposition — is the primary way carbon is transferred from the atmosphere into soil.

    Under proper management, significant changes in soil carbon can be achieved in a single growing season.

    MINER: Ano nelze to srovnat přímo, spíše podkládá práci J. Hansena.

    Sdílel jsem tu pre-print před pár týdny.

    Equilibrium global warming – a scaling perspective
    https://egusphere.copernicus.org/preprints/2024/egusphere-2024-938/
    For an initial CO2 doubling forcing of 4 W m-2 this yields a total forcing of (4+2)1.25 = 7.5 W m-2. Together with an ECS of 4.8°C, this results in an ESS of (7.5/4)4.8°C = 9°C.

    As demonstrated in the feedback analysis in Section 2.3, the scale factor of 7.5/4 between ESS and ECS is in principle only
    valid for the particular value of ECS under consideration, in this case the recent ‘Hansen value’ of 4.8°C.

    In total, the above analysis leads to a 4°C future warming in the pipeline on top of the 2°C ‘Paris’ setpoint, resulting in an
    Equilibrium global warming of about 6°C. This value sits more or less in between today’s actual warming of 1.2°C and the
    expected 10°C warming for today’s GHGs concentrations in the atmosphere reported in the recent Hansen study
