    Paleotemperature proxy data form the cornerstone of paleoclimate research and are integral to understanding the evolution of the Earth system across the Phanerozoic Eon. Here, we present PhanSST, a database containing over 150,000 data points from five proxy systems that can be used to estimate past sea surface temperature. The geochemical data have a near-global spatial distribution and temporally span most of the Phanerozoic. Each proxy value is associated with consistent and queryable metadata fields, including information about the location, age, and taxonomy of the organism from which the data derive. To promote transparency and reproducibility, we include all available published data, regardless of interpreted preservation state or vital effects. However, we also provide expert-assigned diagenetic assessments, ecological and environmental flags, and other proxy-specific fields, which facilitate informed and responsible reuse of the database. The data are quality control checked and the foraminiferal taxonomy has been updated. PhanSST will serve as a valuable resource to the paleoclimate community and has myriad applications, including evolutionary, geochemical, diagenetic, and proxy calibration studies.

    TADEAS: "Vstřícnější pohled na ni mají české firmy, obce a odborníci. Veřejná debata se proměňuje zejména vlivem války na Ukrajině ve prospěch energetické bezpečnosti a urychlení zelené transformace." .. vstricnejsi pohled na ni maji leda odbornici na medialni diskurz a energeticka bezpecnost rozhodne nejde ruku v ruce s zelenou transformaci, naopak zavislost na plynu jako tranzitivnim palivu je vyslovene nebezpecna.

    YMLADRIS: podle electricity map zatím vyrábí kolem 50-60MW a občas se vypne úplně, probíhají testy. Myslím že tak od půlky března by měl běžet naplno.

    KEB: dělám si legraci maximálně z lidí, který se nad tím pohoršujou, protože jsou na tom o level hůř než ty co se lepěj a pak jedou na bali. jinak to beru smrtelně vážně.

    vzít to skutečně vážně by znamenalo obětovat se, obětovat celej životní způsob, transfírmívat tu libidinální strukturu, jak tu někdo psal. chce to někdo? asi tak jeden z bambiliónu

    TADEAS: můžeš si z toho dělat legraci, ale celý LG se tím krásně zdiskreditoval. I ta praštěná greta použila do států plachetnici. Právě proto, aby ukázala, že to jde. Lepit se jeden den k silnici a blokovat lidi co jedou do práce a pak letět letadlem na druhý konec světa a tvářit se, že je to něco úplně jiného, je prostě chucpe

    2022 Persistent soil carbon enhanced in Mollisols by well-managed grasslands but not annual grain or dairy forage cropping systems
    https://www.pnas.org/doi/10.1073/pnas.2118931119

    Intensive crop production on grassland-derived Mollisols has liberated massive amounts of carbon (C) to the atmosphere. Whether minimizing soil disturbance, diversifying crop rotations, or re-establishing perennial grasslands and integrating livestock can slow or reverse this trend remains highly uncertain. We investigated how these management practices affected soil organic carbon (SOC) accrual and distribution between particulate (POM) and mineral-associated (MAOM) organic matter in a 29-y-old field experiment in the North Central United States and assessed how soil microbial traits were related to these changes. Compared to conventional continuous maize monocropping with annual tillage, systems with reduced tillage, diversified crop rotations with cover crops and legumes, or manure addition did not increase total SOC storage or MAOM-C, whereas perennial pastures managed with rotational grazing accumulated more SOC and MAOM-C (18 to 29% higher) than all annual cropping systems after 29 y of management. These results align with a meta-analysis of data from published studies comparing the efficacy of soil health management practices in annual cropping systems on Mollisols worldwide. Incorporating legumes and manure into annual cropping systems enhanced POM-C, microbial biomass, and microbial C-use efficiency but did not significantly increase microbial necromass accumulation, MAOM-C, or total SOC storage. Diverse, rotationally grazed pasture management has the potential to increase persistent soil C on Mollisols, highlighting the key role of well-managed grasslands in climate-smart agriculture

    A ​93km air conditioned covered cycleway has been proposed for Dubai, with the planning firm behind the idea claiming it could make cycling and walking the main mode of transport for 80 per cent of the city’s 3 million residents by 2040.

    US takes action to avert human existential catastrophe: The Global Catastrophic Risk Management Act (2022)
    https://adaptresearchwriting.com/2023/02/05/us-takes-action-to-avert-human-existential-catastrophe-the-global-catastrophic-risk-management-act-2022/

    TLDR:

    - Global catastrophic risks (GCRs) include those events or incidents consequential enough to significantly harm or set back human civilization at the global scale (including: severe global pandemics, nuclear war, asteroid and comet impacts, supervolcanoes, sudden and severe changes to the climate, and intentional or accidental threats arising from the use and development of emerging technologies).

    - Recognising the potentially unbearable impact of global catastrophic risks, the US has just passed the Global Catastrophic Risk Management Act.

    - The Act requires the Secretary of Homeland Security and the Administrator of the Federal Emergency Management Agency to coordinate an assessment of GCRs within one year, and every ten years thereafter.

    - The report must be coordinated with senior officials from 16 other specified national agencies.

    - Each Federal Interagency Operational Plan will then be updated to include an annex containing a strategy to ensure basic needs are met in the aftermath of global catastrophe.
