    PETER_PAN: mi to připadá úplně jasny, ve smyslu že takhle chápu US kulturu. Něco jako přemnoží se ti někde něco, tak to posypes roundupem nebo postrikas biolitem. Technicistni řešení, které nepotřebuje měnit příčiny, dohadovat se s celým světem, prosazovat daně, brzdit kapitalismus apod

    Kolem 2040 uz budou ekonomické škody z extrémních jevů velké a so2 bude mít plošnou podporu

    YMLADRIS: Jako hlasoval jsem NE. Ale nelze vyloucit nejakou aktivitu nejakeho statu ci instituce. Jsem ale presvedcen ze vedecky consensus na tom nebude a nikdo jako IPCC to nedoporuci.

    Prostredky by uz davalo smysl investovat do jinych veci, jako treba zachytavani methanu ze vzduchu.

    SEJDA: nord stream byl uplne malinkaty prd oproti tem unikum v ruznych stanech za posledni dekady..

    Ale to co to radove bude prevysovat budou uniky z prirodnich rezervoaru vlivem tani permafrostu a dalsim pohybum.

    PETER_PAN: tak mame za sebou i dva nejvetsi industrialni uniky metanu: nord streamy a nejaka ta havarie v Azerbajdzanu. Ale na te mape severniho more hodne svitily i plynova pole v Rusku, na polostrove i na Sibiri.

    Povrchová teplota severního Atlantiku dosáhla rekordní hodnotu každý den za posledních 365 dní. Jde o bezprecedentní situaci v historii moderních měření teploty oceánů (Grafika: Nahel Belgherze).

    MATT: meli jsme prave pred casem takovou intimni chvilku s jednim klimatologem. Rikal mi, ze nadeji zabalil uz pred hodne dlouhou dobou. Jenomze pry zeny a jejich lifeforce je silnejsi, takze zena ho presvedcila, ze je potreba pokracovat, maji malou dceru a t d

    tak nevis, co bude. nikdo to nevi.

    YMLADRIS: kdyz jsem v 2005 psal bakalarku o vlivu klima. zmeny na vybrane ekosystemy, tak jsem planoval mit do 2020 statek na samote a nejak se tam pripravovat, akorat prisli deti, vsechno podrazilo a hniju porad v podnajmu v praze... takze vsichni ne.. ;)

    Is Blocking The Sun Quietly Being Normalized? - Spirit of Change Magazine
    https://www.spiritofchange.org/is-blocking-the-sun-quietly-being-normalized/

    Officially, there’s an international moratorium on attempts to block the sun, as well as a U.N. Environmental Modification Convention, but rogue “Greenfinger” billionaires like Bill Gates have continued their dangerous experiments.

    Since the Vietnam War’s Project Popeye scandal, the U.S. government has positioned the Pentagon’s weather modification work and DARPA funding as countering the potential “security threat” geoengineering posed.

    Recently there’s been a shift. The U.S. has begun to normalize solar geoengineering as a “climate solution.” In 2021, the National Academies of Sciences issued a report calling for a $200 million 5-year investment in solar geoengineering research, and in 2023 President Biden released a solar radiation modification (SRM) framework, claiming that “SRM offers the possibility of cooling as the planet significantly on a timescale of a few years.”

    Around the same time, the European Union floated “a potential international framework” for solar geoengineering.

    Meanwhile, climate-profiteering corporations are lobbying for solar geoengineering to be included in the offset market being negotiated under the United Nations Framework Convention on Climate Change.

    Even “environmental” non-profit advocacy groups are in on it!

    The Environmental Defense Fund (EDF)’s official position on geoengineering is that, “Deliberate climate interventions such as albedo modification should not be undertaken for the foreseeable future as they present serious ecological, moral and geopolitical concerns.”

    But, EDF has publicly supported research into geoengineering since 2010, when it co-founded the Solar Radiation Management Governance Initiative with the Royal Society and The World Academy of Sciences.

    In early 2024, Climate Wire reported that EDF organized a private two-day meeting of climate scientists, environmental activists and philanthropists “to prepare for an expected surge of Silicon Valley funding related to last-ditch measures for slowing global warming.”

    “Cooling credits” are not a viable climate solution | Climatic Change
    https://link.springer.com/article/10.1007/s10584-023-03561-w

    As the world struggles to limit warming to 1.5 or 2 °C below pre-industrial temperatures, research into solar climate interventions that could temporarily offset some amount of greenhouse gas-driven global warming by reflecting more sunlight back out to space has gained prominence. These solar climate intervention techniques would aim to cool the Earth by injecting aerosols (tiny liquid or solid particles suspended in the atmosphere) into the upper atmosphere or into low-altitude marine clouds. In a new development, “cooling credits” are now being marketed that claim to offset a certain amount of greenhouse gas warming with aerosol-based cooling. The science of solar climate intervention is currently too uncertain and the quantification of effects insufficient for any such claims to be credible in the near term. More fundamentally, however, the environmental impacts of greenhouse gases and aerosols are too different for such credits to be an appropriate instrument for reducing climate risk even if scientific uncertainties were narrowed and robust monitoring systems put in place. While some form of commercial mechanism for solar climate intervention implementation, in the event it is used, is likely, “cooling credits” are unlikely to be a viable climate solution, either now or in the future.

    Two new Mexico teams to explore impacts of SRM on heatwaves and biodiversity loss - The DEGREES Initiative
    https://www.degrees.ngo/two-new-mexico-teams-explore-srm-heatwaves-and-biodiversity-loss/

    By modelling the potential impacts of SRM and climate change, these scientists will contribute to an evidence base that policy makers in Mexico and Central America can use to make informed decisions about reducing climate risks. This is research conducted by Latin Amercian scientists working at a Mexican University, who will communicate their findings openly to key stakeholders through peer-reviewed academic publications.

    Last year, Mexico announced an intention to ban outdoor solar geoengineering activities after an American start-up company attempted a small-scale SRM balloon test on Mexican territory.

    Unlike that controversial small-scale for-profit ‘deployment’, the two new Degrees-funded scientific teams will conduct responsible computer-based modelling research on the potential effects of SRM on climate change, heatwaves, and biodiversity. This supports Degrees’ central mission – while we take no position on whether SRM should ever be used, we want developing countries to have the capacity to do their own research and to have an informed role in any future governance discussions and decisions on its use or non-use.

    Global warming is accelerating. There's only one thing we can do today to delay it before we burn, enough to solve the pbm: SO2 injection

    Some ppl are squeamish about it but they shouldn't be. SO2 is so obviously the right solution that we should do it now. Here's why

    SHEFIK: tak hallam to asi bere tak, že collapse-aware lidem naopak naději dává, tím že buduje představu, že by se mohlo začít šlapat na brzdu třeba 50x silněji, kdyby se zanechalo všech kravin

    Lidi bez naděje se IMHO odstěhovali do hor a už se jen kochaji vyhlidkou

    SHEFIK: nemáme data, můžeme mít jen pocity zda doomismus a jaká míra doomismu má konstruktivní / destruktivní efekt, tak nevím. taky si nemyslím že extinction je main scenario

    Nicméně přijde mi zajímavý že o téma vedle - extinction caused by AI - se neustále diskutuje a uvažuje se o tom. Není v tom ten odsudek typu "panikou ničemu nepomůžeš"

    Rozdíl vidím v tom, že klima doomismus požaduje okamžitý degrowth takže lidi s tím prostě nemůžou souhlasit (zničilo by to životní styl), takže se varianta extinction nepřipouští a neuvažuje. Přitom ty vzájemně se násobící domina působí plausibilně, tak vyloučit extinction nemůžeš

    Zatímco "vypnout AI" lidem nesahá na životní styl, takže to má mnohem víc proponentů
