    TUHOKlimaticka zmena / Thank you so much for ruining my day


    "Given the sheer enormity of climate change, it’s okay to be depressed, to grieve. But please, don’t stay there too long. Join me in pure, unadulterated, righteous anger."


    "I don’t want your hope. I don’t want you to be hopeful. I want you to panic. I want you to feel the fear I feel every day. And then I want you to act. Once you start to act, the hope is everywhere."

    "Our best scientists tell us insistently that a calamity is unfolding, that the life-support systems of the Earth are being damaged in ways that threaten our survival. Yet in the face of these facts we carry on as usual."

    “We’ve got to stop burning fossil fuels. So many aspects of life depend on fossil fuels, except for music and love and education and happiness. These things, which hardly use fossil fuels, are what we must focus on.”

    A nejde o to, že na to nemáme dostatečné technologie, ty by na řešení použít šly, ale chybí nám vůle a představivost je využít. Zůstáváme při zemi, přemýšlíme až moc rezervovaně. Technologický pokrok to sám o sobě nevyřeší. Problém jsme my, ne technologické nástroje.

    Rostouci hladiny oceanu, zmena atmosferickeho proudeni, zmeny v distribuci srazek a sucha. Zmeny karbonoveho, fosforoveho a dusikoveho cyklu, okyselovani oceanu. Jake jsou bezpecnostni rizika a jake potencialni klady dramatickych zmen fungovani zemskeho systemu?
    Ale take jak funguji masove dezinformacni kampane ropneho prumyslu a boj o verejne mineni na prahu noveho klimatickeho rezimu post-holocenu.

    TUHO: Cely rozhovor s Pokornym je tady http://www.cts.cuni.cz/soubory/Media/Pokorny_Nas%20boj%20s%20klimatickou%20zmenou.pdf . Procetl jsem si to, peclive. On tam vlastne nakonec priznava, ze to dost mozna problem je, akorat muj dojem je, ze si vybral proste nejakou pozu (skeptickou) a tu ted bude uz jen tezko snimat - obzvlaste, kdyz mu prinasi medialni pozornost. V rozhovoru napr priznava, ze okyselovani oceanu je problem. Zrovnatak priznava, ze je treba najit nahradu za fosilni paliva. On vlastne jen proste nema rad ten hype a zatvrzele jede ve svych scholastickych schematech a la "nevime to presne" (to nebudeme vedet nikdy), nebo "1.5C je jeste snesitelne" (to ano, ale to dame do konce teto dekady, a potom?) ... Nejsem si jist, nakolik ma smysl ty jeho kecy debunkovat. Mu totiz jde o tu pozornost. IMHO je efektivnejsi proste jen dokola opakovat ve strucnosti zavery IPCC. To delam ja v rodine - rikam lidem: okay, ty si myslis toto, to je v pohode. Ja cerpam z IPCC a ti rikaji toto. Nema smysl se hadat z plochozemci ...

    Dale od ni zajimave:

    A major cause of uncertainties in climate projections is our imprecise knowledge of how much warming should occur as a result of a given increase in the amount of carbon dioxide in the atmosphere. Paleoclimate records have the potential to help us sharpen that understanding because they record such a wide variety of environmental conditions. Tierney et al. review the recent advances in data collection, statistics, and modeling that might help us better understand how rising levels of atmospheric carbon dioxide will affect future climate.

    The Detection and Attribution of Northern Hemisphere Land Surface Warming (1850–2018) in Terms of Human and Natural Factors: Challenges of Inadequate Data
    Climate | Free Full-Text | The Detection and Attribution of Northern Hemisphere Land Surface Warming (1850–2018) in Terms of Human and Natural Factors: Challenges of Inadequate Data

    The IPCC AR6 concluded that “climate models can only reproduce the observed warming […] when including the effects of human activities […], in particular the increasing concentration of greenhouse gases”, and that “simulations that include only natural process, including internal variability related to El Niño and other similar variations, as well as variations in the activity of the sun and emissions from large volcanoes […], are not able to reproduce the observed warming” (AR6, FAQ 3.1, p. 515) [1]. Largely on this basis, AR6 concluded that contemporary climate change is “overwhelmingly due to human influence” (Technical Summary, p. 11). However, in this article, we argue that this confident “detection and attribution of climate change” statement was unjustified because it failed to satisfactorily assess two key ongoing scientific debates:

    1. How much of the warming since the 19th century implied by current global temperature estimates is an artifact of urbanization biases?
    2. Have we established a reliable solar forcing dataset for estimating the solar contribution to these trends?

    Empirical assessment of the role of the Sun in climate change using balanced multi-proxy solar records
    https://www.sciencedirect.com/science/article/pii/S1674987123001172

    • Factors other than direct TSI forcing account for around 80% of the solar influence on the climate.
    • Important solar-climate mechanisms to be investigated before developing reliable GCMs.


    ...empirical studies often found that the solar contribution to climate changes throughout the Holocene has been significant, whereas GCM-based studies, which only adopt radiative forcings, suggest that the Sun plays a relatively modest role.

    The CMIP6 GCMs appear to greatly underestimate the Sun’s role in climate change because of two major limitations: erroneous solar forcings have likely been integrated into the models; and TSI alone appears to likely be not the most important solar forcing. Additional solar-magnetism related forcings and associated mechanisms are not included in the GCMs because they are currently poorly understood, despite the fact that there are several empirical indications that they might sufficiently modulate the cloud cover system (by 5% or less) to explain a significant component of the observed climatic changes.

    At least about 80% of the solar influence on the climate could be generated by processes other than direct TSI forcing. If this result is correct, several solar-climate mechanisms must be thoroughly investigated and fully understood before reliable GCMs can be developed.

    Europe could become energy self-sufficient in $2 trillion push, study says | Reuters
    https://www.reuters.com/markets/europe/europe-could-become-energy-self-sufficient-2-trillion-push-study-2023-10-04/

    The report, led by the Potsdam Institute for Climate Impact Research, said the continent would require annual investments of 140 billion euros by 2030 and 100 billion a year in the decade thereafter to get there.

    While most of the sum would be needed for onshore wind expansion, solar, hydrogen and geothermal resources would be additional pillars of a strategy that would enable Europe's electricity needs to be powered exclusively from renewables by 2030.

    It would take another decade to convert the entire energy system, including things such as heating currently powered by oil or gas, to renewables, according to the study, which was shared with Reuters.
