    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.

    the question is what brings us back [ from over 1.5C warming ] and the only chance of coming back is the biosphere

    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).

    JIMIQ: jo, mraky, aerosoly, snih, znecisteni oceanu, zmeny vegetace.

    tak snad se toho nechytnou dezoláti a nehoděj to na solární panely :)
    asi je to snížením ledové/sněhové plochy, ne?

    JIMIQ: albedo = odrazivost. tedy snizuje se albedo = snizuje se odrazivost = zvysuje se mnozstvi pohlcene energie = zvysuje se teplota. blby

    JIMIQ: outgoing je odrazene .. takze klesa podil odrazeneho. Tak jako na druhem grafu roste pohlceny plosny vykon.

    SEJDA: jo já vím jak v principu funguje albedo, ale zajímá mě jestli se zhoršuje nebo zlepšuje, protože to z těch čísel grafu nepoznám :D jsou to % odrazivosti, nebo % pohlcení?

    JIMIQ: ze se Zeme ohriva nejen sklenikovym plyny (ktere pohlcuji infracervene zahreni Zeme), ale i ze Slunce, tim jak Zeme meni svoji odrazivost.
    Jako by bylo mene bilych mraku ve vysokych vrstvach atmosfery ale vice tech sedych v nizsich vrstvach (ktere jsou pri pohledu ze shora namodrale).
