    TUHOKlimaticka zmena / If the fracturing of our once stable climate doesn’t terrify you, then you don’t fully understand it


    "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.

    V roce 2018 už byl tento „fakt“ akceptován a doložen další studií, kdy už se hovořilo o ochlazení v regionálním měřítku o 1 °C. A tehdy se také začalo šířeji diskutovat o pozitivech skleníkové krajiny Plastového moře.

    ...

    Až 45 % celkové uhlíkové stopy zdejšího skleníkového zemědělství lze považovat za kompenzované zvýšeným albedem, které neutralizuje globální oteplování v oblasti, a také v planetárním měřítku, kde částečně kompenzuje celkovou uhlíkovou stopu.

    Mexican mangroves have been capturing carbon for 5,000 years
    https://phys.org/news/2022-09-mexican-mangroves-capturing-carbon-years.html

    The team expected that carbon would be found in the layer of peat beneath the forest, but they did not expect that carbon to be 5,000 years old. This result, along with a description of the microbes they identified, is now published in the journal Marine Ecology Progress Series.

    ...

    There are more than 1,100 types of bacteria living beneath the mangroves that consume and excrete a variety of chemical elements. Many of them function in extreme environments with low or no oxygen. However, these bacteria are not efficient at breaking down carbon.

    ...

    These sites are protecting carbon that has been there for millennia. Disturbing them would cause a carbon emission that we wouldn't be able to repair any time soon," said Matthew Costa, UC San Diego coastal ecologist and first author on the paper.

    The study further noted that atmospheric increase in Iodine loading due to enhanced anthropogenic Ozone-induced ocean Iodine emissions, as well as the thinning and shrinking of Arctic sea ice expected in the near future, will probably lead to increases in Iodine emissions.

    "These results indicate that iodine chemistry could play an increasingly important role in the future and must be considered for accurate quantification of the ozone budget in the Arctic," IITM said in a release.

    The recent declines in surface winds over Europe renewed concerns about a “global terrestrial stilling” linked with climate change. From 1978 until 2010, research showed a worldwide stilling of winds, with speeds dropping 2.3 percent per decade. In 2019, though, a group of researchers found that after 2010, global average wind speeds had actually increased — from 7 miles per hour to 7.4 miles per hour.
    Despite those conflicting data, the Intergovernmental Panel on Climate Change forecasts slowing winds for the coming decades. By 2100, that body says, average annual wind speeds could drop by up to 10 percent.
    “Why do we have wind at all on the planet?” asks Paul Williams, who studies wind as a professor of atmospheric science at the University of Reading in England. “It’s because of uneven temperatures — very cold at the poles and warm at the tropics. That temperature difference drives the winds, and that temperature difference is weakening. The Arctic is warming faster than the tropics.”

    nothing new really....

    This is a *HUGE* freaking deal: Congress has obtained documents that show Big Oil companies actively lying about their climate commitments and coordinating to downplay their support for the Paris Agreement.

    That's fraud.

    The NYT article says the committee has thousands of more pages they are working through and will be releasing more soon.
    That should have Big Oil *very* worried.

    Clean energy could save trillions of dollars
    A rapid transition to clean energy sources will save the world as much as US$12 trillion — even without accounting for the climate benefits. A study modelling the future cost of renewables and fossil fuels finds that the cost of solar and wind power has fallen more than was estimated in past projections. And the price will continue to drop quickly — although how much will depend on whether the world adopts aggressive climate policies and achieves the highest rates of technological innovation. “Even if you're a climate denier, you should be on board with what we're advocating,” says complex-systems scientist and co-author Doyne Farmer. “Our central conclusion is that we should go full speed ahead with the green energy transition because it's going to save us money.”

    This Zero Emission Mobility (ZEM) EV captures carbon
    https://electrek.co/2022/09/14/this-zero-emission-mobility-zem-ev-captures-carbon/

    According to team estimates, the ZEM uses two filters that can capture up to 2kg (about 4.4 lbs) of CO2 as the EV travels 20,000 miles. Although this may not seem like much, around 10 ZEMs can absorb around as much carbon as an average tree.

    The team is in the process of obtaining a patent for their CO2 filter with plans to increase capacity in the coming years.

    YMLADRIS: ted uz zas zabredavame do politiky, snazil sem se to drzet kolem tech emisi, ale teda pojdme tu diskuzi zkusit dokoncit.

    Trzni ekonomika se nesnazi drzet u moci vladnouci vrstvu. To uz pak neni trzni ekonomika, ani demokracie. Je ale fakt, ze slabinou kazdeho lidskeho uskupeni je bud (vladni) moc, nebo penize, kterymi se da (vladni) moc korumpovat. Tomu se ani trzni prostredi nevyhne a zakony budou vzdy pozadu za lidskou vynalezavosti

    Centralni planovani ma vyhodu v tom, ze dokaze presmerovat priority velke masy lidi k jednomu, ci nekolika malo cilum. Na historii ruznych statu je ale jasne videt, ze stat je komplexnejsi nez jedno tema a pak zacnou ty ostatni trpet. Klima take neni jen o elektromobilite, ale tech akci je potreba vyrazne vic a potrebujeme i jakykoliv dalsi progress v technologiich - ten centralne nenaplanujes, vychazi z miry motivace.

    Trzni ekonomika je v totalu nejefektivnejsi, aby byly uprednostnovane vsechny oblasti, ktere jsou pro spolecenstvi lidi v danou chvili potrebne/prioritni. Vyjadreno financni hodnotou, ktera neni nicim jinym, nez ocenenim prace (hodnoty tvoji/moji prace pro spolecnost).

    YMLADRIS: ja se v tom nemam o co oprit, protoze nevim, jaky plan ma ta centralne planovava ekonomika. Centralne planovana ekonomika dokaze neuveritelne veci, napriklad zastropovat lidem pocet deti. (Coz, jak vis, by byl nejvetsi zářez do energetické náročnosti lidstva.) Na druhou stranu, centralne planovana ekonomika typicky ma hlavni zajem - udrzet u moci vladnouci vrstvu, v cemz se nelisi od trznich ekonomik, takze tezko rict jestli z praktickeho hlediska se da jasne rict, ktera z nich je zelenejsi.
