    GOJATLA: elektrický auta jsou hopium a ve skutečnosti to problém (životní styl) neřeší?

    ale samozřejmě, můžeš to brát tak že klimatická změna je jediný problém životního prostředí, pak by to sem nepatřilo. jen abys nevylil vaničku i s dítětem.

    Study finds total PM10 emissions from EVs equal to those of modern ICEVs; role of weight and non-exhaust PM - Green Car Congress
    https://www.greencarcongress.com/2016/04/20160418-pm10.html
    Because there is little research which has investigated the actual reduction in emissions resulting from EV braking, Timmers and Achten assumed a conservative estimate of zero brake wear emissions for EVs.

    Climate impacts on global agriculture emerge earlier in new generation of climate and crop models | Nature Food
    https://www.nature.com/articles/s43016-021-00400-y

    Here we report new twenty-first-century projections using ensembles of latest-generation crop and climate models. Results suggest markedly more pessimistic yield responses for maize, soybean and rice compared to the original ensemble. Mean end-of-century maize productivity is shifted from +5% to −6% (SSP126) and from +1% to −24% (SSP585)—explained by warmer climate projections and improved crop model sensitivities. In contrast, wheat shows stronger gains (+9% shifted to +18%, SSP585), linked to higher CO2 concentrations and expanded high-latitude gains. The ‘emergence’ of climate impacts consistently occurs earlier in the new projections—before 2040 for several main producing regions. While future yield estimates remain uncertain, these results suggest that major breadbasket regions will face distinct anthropogenic climatic risks sooner than previously anticipated.

    If you care about the impacts of air quality, a reminder that electric cars only solve half of the problem. PM pollution from braking and tire wear is the same as any fossil fuel vehicle.

    The headlines today are about a "landmark" pledge to stop deforestation by 2030. The only problem? World governments made *exactly* the same pledge in 2014 and deforestation increased by 40%

    How Much of the Worsening Energy Crisis is Due to Depletion? - Resilience
    https://www.resilience.org/stories/2021-11-02/how-much-of-the-worsening-energy-crisis-is-due-to-depletion/

    Policy makers envision an energy transition in which solar and wind seamlessly and quickly substitute for coal, oil, and gas, leaving consumers enjoying just the same comforts and conveniences as they do now, while emitting no carbon. That’s an exceedingly unlikely scenario. The real energy transition will almost certainly be a shift from using a lot to using a lot less.

    If that’s true, then what should we do? Over a dozen years ago, I was among several energy analysts and commentators who recommended the adoption of depletion protocols (which are essentially programs for conserving and rationing nonrenewable resources) as a policy tool for helping society adapt to the inevitable end of the fossil fuel era. Politicians were uninterested. Today, rationing is still the best policy response. Energy could be rationed in several different ways; in addition to depletion protocols, another rationing approach I’ve long liked is tradable energy quotas, which effectively provide monetary incentivizes to those who use less energy. With rationing, those who use the most sacrifice the most, while those who use the least maintain (or gain) access to necessities.

    There were always two reasons to reduce society’s reliance on fossil fuels: pollution and depletion. Pollution has taken center stage via climate change. But as long as we keep extracting and burning coal, oil, and natural gas, our depletion problem likewise keeps simmering away in the background.

    Greta Thunberg and Vanessa Nakate's Open Letter to the Media | Time
    https://time.com/6111851/greta-thunberg-vanessa-nakate-open-letter-media/

    as we don’t have the technological solutions that alone will do anything close to that in the foreseeable future, it means we have to make fundamental changes in our society. This is the uncomfortable result of our leaders’ failure to address this crisis.

    Your responsibility to help correct this failure cannot be overstated. We are social animals and if our leaders, and our media, don’t act as if we were in a crisis then of course we won’t understand that we are. One of the essential elements of a functioning democracy is a free press that objectively informs the citizens of the great challenges our society faces. And the media must hold the people in power accountable for their actions, or inactions.

    You are among our last hopes. No one else has the possibility and the opportunity to reach as many people in the extremely short timeframe we have. We cannot do this without you. The climate crisis is only going to become more urgent. We can still avoid the worst consequences, we can still turn this around. But not if we continue like today. You have the resources and possibilities to change the story overnight.

    Whether or not you choose to rise to that challenge is up to you. Either way, history will judge you.

    Jan Činčera: "Možnosti jednotlivce ovlivnit velké dění ve ve světě je jedno z těch témat, o kterých můžeme nekonečně diskutovat. O roli Grety Thunberg se psalo a píše dost, k dispozici teď máme i první výzkumy. Tým Sabherwai et al. zkoumal, zda to, jestli člověk (tedy, Američan) zná Gretu Thunberg, souvisí s jeho přesvědčením, že společně s ostatními dokáže udělat účinnou akci na ochranu klimatu (collective efficacy) a zda takové přesvědčení pak následně motivuje k akcím na ochranu klimatu (intentions to engage in collective action).
    Na obojí našli kladnou odpověď. Akce Grety Thunberg tedy podle autorů posilují naši víru, že můžeme společně klima chránit a ta se pak promítá do našich akcí.
    Na zjištěný vztah přitom nemá vliv věk. Ovlivňuje jej ale politické přesvědčení - liberální názory jej posilují, konzervativní oslabují. ("Moderated mediation models testing age and political ideology as moderators of the “Greta Thunberg Effect” indicate that although the indirect effect of familiarity with Greta Thunberg via collective efficacy is present across all age-groups, and across the political spectrum, it may be stronger among those who identify as more liberal (than conservative). Our findings suggest that young public figures like Greta Thunberg may motivate collective action across the U.S. public, but their effect may be stronger among those with a shared political ideology.")
    Zatím nevíme, jak celý tenhle náš klima příběh dopadne a zda v něm nakonec hlavní roli nesehraje jeden tvrdohlavý senátor ze Západní Virgínie, narcisistní americký ex-prezident, excentrický, miliardami oplývající vizionář nebo někdo jiný, mnohem blíže odpovídající definici osoby oplývající prostředky a mocí. Ale je každopádně zajímavé, že i malí a zdánlivě bezmocní mohou hýbat světem.
