    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).

    Europe unprepared for rapidly growing climate risks, report finds | Climate crisis | The Guardian
    https://www.theguardian.com/environment/2024/mar/10/europe-unprepared-for-climate-risks-eea-report

    The report looks at how severe the climate threats are and how well prepared Europe is to deal with them. It says the most pressing risks – which are growing worse as fossil fuel pollution heats the planet – are heat stress, flash floods and river floods, the health of coastal and marine ecosystems, and the need for solidarity funds to recover from disasters.

    When the researchers reassessed six of the risks for southern Europe, which they described as a “hotspot” region, they found urgent action was also needed to keep crops safe and to protect people, buildings and nature from wildfires.

    There is increasing evidence of adaptation but “it’s certainly not enough”, said Robbert Biesbroek, a report author from Wageningen University, who also co-led the chapter on Europe in the latest Intergovernmental Panel on Climate Change (IPCC) report on adaptation.

    “It’s not going quickly enough and it’s not reaching the ones that need it most,” he said. “It’s quite scary in that sense.”

    The report also warns of “cascading and compounding” risks, which it says current stress tests in the financial sector are likely to underestimate. Hot weather will dry out southern Europe, for instance, killing crops and shrinking water supplies, but will also harden soils, making flash floods more likely, and dry out vegetation, meaning wildfires can spread faster
