    TUHO: Tady kdyztak summary 30 let prace Rahmstorfa na tema. Relativne kratkej clanek, hodne dat, obrazku, srozumitelny pro vetsinu lidi

    The Atlantic Meridional Overturning Circulation has a major impact on climate, not just in the northern Atlantic but globally. Paleoclimatic data show it has been unstable in the past, leading to some of the most dramatic and abrupt climate shifts known. These instabilities are due to two different types of tipping points, one linked to amplifying feedbacks in the large-scale salt transport and the other in the convective mixing that drives the flow. These tipping points present a major risk of abrupt ocean circulation and climate shifts as we push our planet further out of the stable Holocene climate into uncharted waters.

    Udrzitelny jerky :)

    Hmyzí žvýkání. Sens vyvinuli světově unikátní cvrččí jerky — Forbes
    https://forbes.cz/cvrcci-revoluce-firma-sens-uvadi-na-trh-inovaci-v-udrzitelne-strave/

    Jerky z cvrčků, které se vzhledem i chutí podobají opravdovému sušenému masu, jsou vyrobeny ojedinělou technologií z cvrččího proteinu a rostlinných bílkovin. „Na dva naše balíčky cvrččích jerky ale spotřebujeme téměř o tři tisíce litrů vody méně a vyprodukuje se také stokrát méně CO2,“ tvrdí spoluzakladatel Sens Radek Hušek.

    Why more teens are rejecting drivers licenses and choosing e-bikes
    https://electrek.co/2024/06/10/why-more-american-teenagers-are-rejecting-drivers-licenses-in-favor-of-e-bikes/

    the number of teens with driver’s licenses has fallen by about 8% over the past two decades, according to the latest data from the Federal Highway Administration. The e-bikes also grant more independence to teens not yet old enough to drive.”
    ...
    For many teens and their families, the cost of car ownership is a significant deterrent. From the price of the vehicle itself to insurance, fuel, and maintenance, the expenses can quickly add up.

    E-bikes, on the other hand, offer a more affordable alternative. The initial purchase price is considerably lower, and operational costs are almost zero, outside of occasional new brake pads and tires. With the rising cost of living, many families find e-bikes to be a financially savvy choice.
    ...
    Much more so than a generation ago, today’s teenagers are increasingly environmentally conscious. The impact of climate change and the importance of sustainable living are at the forefront of many teenagers’ minds.

    E-bikes, with their zero emissions, offer an eco-friendly alternative to cars. Many teens feel that choosing an e-bike over a car is a tangible way to contribute to a greener planet.

    Will Mexico City Run Out of Drinking Water? | Scientific American
    https://www.scientificamerican.com/article/0424--kinard-mexico-city-run-out-of-water/

    Mexico City i Bogota se blíží do bodu, kdy nebudou mít jeho obyvatelé přístup k pitné vodě. Hlavní město Mexika má přes devět milionů obyvatel a je největším městem na severoamerickém kontinentu. V hlavním městě Kolumbie žije osm milionů lidí. Problémy se suchem se na celém americkém kontinentu stupňují.

    V Mexico City už nyní obyvatelé otáčejí kohoutky s nervozitou, zda voda vůbec poteče. Navíc její kvalita je mizerná. Voda, pokud teče, je hnědá a zapáchá. Klíčové zásobníky na vodu ve městě vysychají. A vedení města už vyzvalo obyvatele, aby vodu používali jen v nejnutnějších případech.

    Stejné problémy hlásí i kolumbijská Bogota, ve které městská rada zavedla přerušování dodávek vody. Tamní starosta vyzval Kolumbijce, aby se v rámci rodin sprchovali společně a na víkendy pokud možno opustili město, aby se spotřeba vody snížila.

    YMLADRIS: jeste teda doplnim okolnosti. Aschenbrenner ma asi pravdu v tom, ze je fakt jen par lidi, kteri maji v tom AGI nastupu situacni awareness a on je jeden z nich. Odesel/vyhozen z Open AI a nevzal si odstupne, aby nemusel podepsat NDA, takze ted muze psat tyto veci. Jestli ale ma "pravdu" to nemuze nikdo z nas laiku vedet.. vlastne ten radikalismus s jakym to vidi odpovida nize zminenemu Rogerovi Hallamovi, oba se snazi burcovat lidi. No tak uvidime, stejne se s tim neda nic moc delat

    YMLADRIS:

    jeho situational awareness ohledne elektriny

    (43) Page 84: To most, this seems completely out of the question. Some are betting on Middle Eastern autocracies, who have been going around offering boundless power and giant clusters to get their rulers a seat at the AGI-table.

    But it’s totally possible to do this in the United States: we have abundant natural gas.

    (44) Page 85: We’re going to drive the AGI datacenters to the Middle East, under the thumb of brutal, capricious autocrats. I’d prefer clean energy too—but this is simply too important for US national security. We will need a new level of determination to make this happen. The power constraint can, must, and will be solved.

    The clusters can be built in the US, and we have to get our act together to make sure it happens in the US. American national security must come first, before the allure of free-flowing Middle Eastern cash, arcane regulation, or even, yes, admirable climate commitments. We face a real system competition— can the requisite industrial mobilization only be done in “topdown” autocracies? If American business is unshackled, America can build like none other (at least in red states). Being willing to use natural gas, or at the very least a broad-based deregulatory agenda—NEPA exemptions, fixing FERC and transmission permitting at the federal level, overriding utility regulation, using federal authorities to unlock land and rights of way—is a national security priority.

    ale dal si mysli ze to ukradne CIna (US vlada nebude schopna rychle z toho udelat Manhattan project) a konci uvahou o svete kde se prejde od AGI k ASI behem roku.. (to uz asi bude jedno, zda v americe nebo v cine)

    (89) Conclusion: And so by 27/28, the endgame will be on. By 28/29 the intelligence explosion will be underway; by 2030, we will have summoned superintelligence, in all its power and might.

    For those of us who get the call to come along for the ride, it’ll be . . . stressful. But it will be our duty to serve the free world—and all of humanity. If we make it through and get to look back on those years, it will be the most important thing we ever did. And while whatever secure facility they find probably won’t have the pleasantries of today’s ridiculouslyovercomped-AI-researcher-lifestyle, it won’t be so bad. SF already feels like a peculiar AI-researcher-college-town; probably this won’t be so different. It’ll be the same weirdly-small circle sweating the scaling curves during the day and hanging out over the weekend, kibitzing over AGI and the lab-politics-of-the-day.

    Except, well—the stakes will be all too real.

    See you in the desert, friends.

    Roger explaining himself

    Nevim zda to nekoho jeste zajima, tyka se to te fear-mongering strategie, Roger napsal dlouhy vysvetlovaci post, ze si mysli, ze je to vic honest and fair, nez kdyz se vedci furt schovavaji za svuj non-emotional pohled. Za me, kazdej dela co se mu vypocitalo, ale bojim se, ze uz to Roger prozkoumal kam az to slo a je to bez efektu..

    ...
    The nerdy scientists are the mirror image of the raging deniers. They feed each other. They both need each other like one of those really perverse dependency relationships. If scientists emote and speak in blunt terms like “my children are going to die”, the deniers give them hell for saying things that are not certain. “Have you proof that your children will die you fucking bunch of fear mongers? No!”. And so the scientists retreat, which suits them just fine because then they can continue to be in their comfort zone of only talking about certainties: “Sorry you are right, there is only an uncertain possibility my children will soon enter into unique levels of discomfort”.

    Both scientists and deniers are not computers - they are humans trying to avoid emotional pain. Both groups can’t cope with me because I am the guy running into the room going: “I don’t give a flying fuck about your fucking certainty analysis - it's my fucking children you total dicks.” That's why I got 1.6 million views. Because I am violating the rules both sides impose on the public sphere. That is why my favourite historical figure, Larry Kramer, was such an effective change-maker. Because he didn’t give a fuck - check him out.

    ...

    This is a roundabout way of saying that when I say, “12% of Phoenix are going to die” I am not really saying 12% of Phoenix are going to die. I am not talking about moss - I am making an emotional, rhetorical and entirely appropriate statement. A deeply true statement in the holistic sense.

    I know 12% of Phoenix might ACTUALLY not die. But that is not the point. The point is this world is so fucked up because we just sit there and continue watching Netflix when we are in this beyond fucking fucked situation.

    Get it yet? What I am ACTUALLY saying is “Wake the fuck up you fucking dicks.”

    The opposite of love is not hate - it's indifference. Hate, don't get me wrong, is a terrible thing but indifference is so much worse. Indifference is death. The first 100-plus hateful comments below my tweet are all calling me a dick. Why? Because they are crying out for this terrible shit show called “Climate” not to be real. Because if it is real, it will be so unbearably upsetting, not just for themselves and those they love, but for their whole sense of the world as something they need to control.

    Dva biliony dolarů na čistá paliva. Letos dvakrát překročí investice do fosilních — Forbes
    https://forbes.cz/dva-biliony-dolaru-na-cista-paliva-letos-dvakrat-prekroci-investice-do-fosilnich/

    Globální investice do technologií čisté energie a infrastruktury budou letos dvakrát vyšší než investice do fosilních paliv.

    Celkové investice do energetiky by letos měly poprvé překročit tři biliony dolarů (67,9 bilionu korun). Ve své zprávě to ve čtvrtek uvedla Mezinárodní agentura pro energii (IEA).

    Do čistých technologií – včetně obnovitelných zdrojů, elektromobilů, jaderné energetiky, sítí, skladování, nízkoemisních paliv, zvyšování účinnosti či tepelných čerpadel – a infrastruktury mají letos směřovat dva biliony dolarů.

    Zbytek půjde do plynu, ropy a uhlí. Kombinované investice do obnovitelné energie a sítí překonaly investice do fosilních paliv poprvé v roce 2023.

    Aquaculture overtakes wild fisheries for first time: UN report
    https://phys.org/news/2024-06-aquaculture-wild-fisheries.html

    With global demand for aquatic foods expected to keep growing, an increase in sustainable production is vital to ensure healthy diets, the United Nations's Food and Agriculture Organization said.

    In 2022, aquaculture yielded 94.4 million tonnes of aquatic animal production -- 51 percent of the total, and 57 percent of the production destined for human consumption, it said.
