    TUHOKlimaticka zmena / Destroying the Future Is the Most Cost-Effective


    "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.

    Aviation industry is ‘failing dramatically’ on climate, insiders say | Airline emissions | The Guardian
    https://www.theguardian.com/environment/2025/may/06/aviation-industry-failing-dramatically-on-climate-insiders-say

    The aviation industry is “failing dramatically” in its efforts to tackle its role in the climate crisis, according to a newly formed group of aviation professionals.

    They say they are torn between their passion for flying and their concern for the planet and are calling for a fundamental transition of the industry, including controlling flight numbers.

    In March (2025?), 440 winter and summer Olympians representing more than 90 countries and 50 sports wroteExternal link an open letter to candidates for the presidency of the International Olympic Committee. They expressed concern about the risks that climate change poses to many sports and called for the organisation to take more action to fight climate change. This included setting standards for sponsorships, upholding sustainable practices, and strengthening commitments to cut carbon emissions.

    Based on daily values, the April average of atmospheric CO₂ was 429.6-429.7 ppm. That's ~3.1 ppm higher than last year, a continued rapid increase!
    It's also the highest concentration that Earth has experienced in the past 15 *million* years.

    Jeff Bezos’ Earth Fund Cuts Off a Key Nonprofit Monitoring Corporate Climate Efforts – Mother Jones
    https://www.motherjones.com/politics/2025/02/jeff-bezo-earth-fund-ends-support-nonprofit-science-based-targets-initiative-sbti-corporate-climate-efforts-paris/

    The Bezos Earth Fund has stopped its support for the Science Based Targets initiative (SBTi), an international body that assesses if companies are decarbonizing in line with the Paris agreement. Earth Fund had been one of two core funders of the SBTi, with the Ikea Foundation: The two accounted for 61 percent of its total funding last year. Earth Fund’s decision was first reported by the Financial Times.

    Spokespeople for Earth Fund and SBTi said the $18 million grant had been a three-year commitment that expired as previously agreed, and Earth Fund had not made a final decision on future support. But researchers familiar with the SBTi, as well as advisers at the organization, raised concerns that the vanishing support was part of a broader trend of wealthy individuals moving away from funding causes that the US president—who has previously called climate change a hoax—did not agree with

    "The Mauna Loa observatory showed the first weekly average CO₂ concentration of >430 ppm in about 3 million years!

    "Including other greenhouse gases, the CO₂-equivalent is at >560 ppm. Which represents more than a doubling of preindustrial CO₂. Without aerosols, this would cause ~5°C of warming."

    Současnost ovládají dva výrazné trendy: prudký rozvoj AI nástrojů a dekarbonizace. Zatímco generativní AI dokáže pomocí velkých jazykových modelů ohromit schopností komunikovat nebo generovat obrázky a videa, spotřeba elektrické energie na tyto procesy roste. Umělá inteligence ale nabízí mnoho užitečnějších využití, která pomáhají s energetickou efektivitou nebo zalesňováním. Rozvoj AI nezastavíme, snižovat její uhlíkovou stopu musíme u zdroje energie.

    SEJDA: tak na zemi během druhohor bylo až 2300 ppm..... tím neříkám že je to dobře protože zvýšení tak nějak zahubilo 90% druhů a těch 10% se během pár milionů let přizpůsobilo což je přesně to co civilizace tak nějak nemá.

    2025 Global Temperature
    https://mailchi.mp/caa/2025-global-temperature

    Global temperature for 2025 should decline little, if at all, from the record 2024 level. Absence of a large temperature decline after the huge El Nino-spurred temperature increase in 2023-24 will provide further confirmation that IPCC’s best estimates for climate sensitivity and aerosol climate forcing were both underestimates. Specifically, 2025 global temperature should remain near or above +1.5C relative to 1880-1920, and, if the tropics remain ENSO-neutral, there is good chance that 2025 may even exceed the 2024 record high global temperature
