    POLITICO:

    „EU UNLIKELY TO RESCUE DYING SOLAR INDUSTRY: European solar producers are hurtling toward extinction after the European Union hinted Tuesday that it wouldn’t bail out ailing manufacturers, POLITICO’s Victor Jack reports. That’s putting thousands of jobs at risk and deals a blow to Europe’s clean-tech ambitions. 
    In a private meeting between the solar industry and the European Commission, the bloc’s competition officials said they wouldn’t change subsidy rules to support the industry without a strong push from the EU governments, a person familiar with the talks told Victor. The person was granted anonymity to speak freely about confidential talks.
    EU solar manufacturers have warned for months that they face an existential crisis with respect to China’s near-total dominance over global supply lines, which has caused a supply glut of dirt-cheap solar panels inside the bloc and left them unable to compete. In the coming week, companies are set to begin laying off the roughly 4,000 skilled workers in the sector.„

    YMLADRIS: Jsem zvědavej, kolik neočekávaných problémů se pak objeví. Já se asi nejvíce teď obávám toho, že to bude argument pro další pálení fosilních paliv. Bude to vycházet nejlevněji - alespoň dokud se neprojeví ty neočekávané následky. Pak přibude kromě fosilní lobby i lobby stříkačů sajrajtu to atmosféry. Nedivil bych se, kdyby to byl nakonec stejný kapitál ...

    dvě studie

    1. že když se aerosol engineering začne až při vysoké globální teplotě, už to nepomůže na ten AMOC problém a celkově oceány, protože vodě trvá dlouho než se přizpůsobí změnám v teplotě vzduchu. Jako že "start soon".

    2. dehydratace atmosféry, seeding clouds / změny ve vodní páře vyšly v nové studii jako že by měly jen malý efekt (je to druhá metoda o které se uvažuje)

    takže "je to špatný nápad (aerosols injection), ale udělá se to, protože je to nejlevnější. Odclonit antropo přírustek teploty by stálo 30 miliard dolarů ročně, tj částku kterou američani vydávají na žrádlo pro domácí mazlíčky."

    We Need to Start Climate Engineering Soon, New Study Says

    PETER_PAN: UN mělo teď setkání v Nairobi na téma climate engineering without reaching any conclusions (research, ban or just do it?).
    Jak jsi psal že není pravděpodobné, že by se to povolilo.

    SEJDA: jde o geologicky pocitani casu, prlto jsem citoval tu myslenku o eventu. epocha je mnohem vetsi celek.. priklad epochy je treba svrchni jura (malm; cca 18mio let) a to my z dnesniho pohledu nemuzem vedet, jak to bude probihat. zatim jsme v geologickym case takovy uprdnuti ve vetru. celej holocen zatim pripomina spis anomalii v ramci pleistocenu.. bavime se o uplne jinejch radech

    PALEONTOLOG: ja jenom rikam, pockejme si jeste 20 let a podom se museze 50 let hadat, jestli Antropocen zacal s objevem parniho stroje anebo az kdyz rupl prah XYZ.
    Podle mne, klimaticky v antropocenu jsme. Gologicky potrebujeme jeste masivnejsi efekt.

    SEJDA: One emerging argument is that the Anthropocene should be defined as an event in geological history — similar to the rise of atmospheric oxygen just over two billion years ago, known as the Great Oxidation Event — but not as a formal epoch. This would make more sense because geological events unfold as transformations over time, such as humans industrializing and polluting the planet, rather than as an abrupt shift from one state to another, says Erle Ellis, an ecologist at the University of Maryland Baltimore County in Baltimore.

    Von der Leyen heads to Greenland as EU seeks materials for green transition | Greenland | The Guardian
    https://www.theguardian.com/world/2024/mar/14/von-der-leyen-greenland-office-eu-green-transition

    She said the minerals agreement is about “benefits on both sides”. Greenland needs bilateral cooperation to develop its mineral sector, she said, which requires significant capital and long-term investment.

    “Development of mines, exports of minerals is of course an important issue for the diversification of the Greenlandic economy,” she said. While fishing, the current top source of income, is not expected to be overtaken for many years, the tourism and minerals sectors are important focuses for growth.

    “If the western world wants sustainable diversified secure value chains, some of these minerals will need to come from countries that are smaller, like Greenland. We don’t have the economic muscles to invest ourselves in the mineral sector,” she said.

    In order to enable the green transition, a “helping hand” from larger economies would be needed, she added.

    TADEAS: tenhle graf absolutně nechápu, ty hodnoty iradiace jsou standardně řádově jiný a mění se zákonitě s albedem. jestli je to je nějaká delta v iradiace z popisu grafu nevyčtu.

    Of the ~340 W/m2 of solar radiation received by the Earth, an average of ~77 W/m2 is reflected back to space by clouds and the atmosphere and ~23 W/m2 is reflected by the surface albedo, leaving ~240 W/m2 of solar energy input to the Earth's energy budget. This amount is called the absorbed solar radiation (ASR).
