    jinak prave probiha projednavani prvni pracovni skupiny (physical basis of climate change) IPCC nad prispevkem do sesteho assesment reportu. nejvetsi udalost pro klima vedu od roku 2014. cely AR6 by mel byt pak venku pristi rok. jsem zvedavej, jak tuhle udalost planetarniho vyznamu budou reportovat media .)

    VOYTEX: :D mas pravdu.

    takze bud tu prirodu nechame (ve vyhranicenych/vetsine mist) si managovat na long run tu rovnovahu samotnou (nechat ten skot a krovi a vse okolo do nakyho equilibria) a nebo musime zacit managovat uplne vsecko (herbicidy a krovinorezy)

    Imho ta druha varianta by byla dost umorna na zdroje, ktery bychom k tomu potrebovali

    TADEAS: Kdyz nechame skot prezvejkat krovi na metan, tak nevim jestli si pomuzeme.
    Navic by musel spasat rychlejs nez se rozsirujou kroviny, takze by ho muselo bejt obrovsky mnozstvi, kterymu by pri dosazeni nami kyzeneho stavu jednou doslo krovi, nasledoval by globalni hladomor divokyho skotu (jehoz oslabeny imunitni system by mohl vyslechtit nejakou peknou bakterii/virus), nacez krovi by se za par mesicu pri absenci predatora vesele vratilo. Naslednou bounce back expanzi krovi by uz ale asi malokdo chtel resit skotokalypsou a naskytla by se tak prilezitost pro vyrobce herbicidu :)

    PER2: znamena to, ze jedno, zda se divas na problematiku klimatu nebo ekosystemu, protoze z hlediska cloveka ma ta problematika stejny koren - v
    rozhodovani potazmo managementu zdroju. takze prisuzovat neco zmene klimatu nebo nevhodnemu managementu ekosystemu - to je v zasade jedno, protoze ten problem resime tim samym

    TADEAS: a co to znamena? :)
    zni to cely pekne, ale rekl bych, ze o spouste veci nerozhodujeme
    TADEAS
    TADEAS --- ---
    PER2: ze problematika je adresovana skrz rovinu rozhodovacich procesu, rozhodnuti je to, co za neco "muze" nakolik se o tom rozhodujeme.

    TADEAS: co z toho plyne?
    TADEAS
    TADEAS --- ---
    PER2: jednoticim tematem (zmena klimatu, management ekosystemu, civilizacni development) a zaroven polem reseni je tak jako tak onen management zdroju, resp. zpusoby rozhodovani :)

    PER2: tak klima meni vsechno, otisk budes mit vsude :)) to samozrejme neznamena, ze tam nejsou otisky jinych problemu (ktery casto muzou bejt dulezitejsi). akoratze malfunctioning treba politickyho systemu nebo praktik zemedelatci je zhusta klima zmenou amplifikovanej. jak se rika, jedna vlocka spusti lavinu, tak dlouho chodis s dzbanem az se utrhne, to byla posledni klapka, bouchly mi saze a dalsi lidove popisy nelinearni dynamiky a bodu zlomu v komplexnich systemech :D

    TUHO:
    Suffering from drought and water shortages since March, they've taken to the streets in the last couple of weeks to express their anger with the government and its poor management of water resources.
    "We've known about the problem of water scarcity and the threat it poses to national security for more than 30 years,"
    According to official figures, Iran now has 192 dams — around 10 times it did some 40 years ago. "The government is seeking quick solutions that promise short-term success.

    "As, for example, when you point out that you shouldn't, on principle, build large dams in a dry country like Iran, because too much water evaporates from the reservoirs."
    Environmental experts have said the current water shortage is also the consequence of a mistaken understanding of agriculture development and progress. The government continues to be focused on maximizing self-sufficiency, not least as a response to sanctions and pressure from abroad.

    It has been promoting agriculture and allowing the digging of deep wells, which have exhausted the available water resources. The traditional crops in Khuzestan are rice and sugar cane, both of which require large amounts of water. Around 90% of Iran's total water consumption is used up by agriculture.


    tldr: lets blame clima change for everything

    PETER_PAN: ok, cerpal sem z webu arniky, moje chyba. NOAA uvadi priblizne 9 let. Kdyz si to srovnam:

    Tak 9x28 je 252, tzn. vyhoreni methanu je 2,5x lepsi pro klima, nez ho nechat uniknout (rozpad co2 se udava na 100 let). Navic je u ketanu ten efekt pusobeni intenzivnejsi vuci moznym tipping points a zkracuje mozny reakcni cas lidstva, takze jednoznacne vychazi lip ho nechat shoret.

    Uz jen skoda, ze spolecne s nim tam hori i ty lesy :)

    Ale reseni methanu v atmosfere (zejmena toho ktery v nasledujicich letech skokove pribude) je IMHO jedna z priorit.
    PETER_PAN

    SHEFIK: Za 4 roky ne. Methan ma half-time v atmosfere cca 7 let a tohle nepresne stanovene cislo se navic meni s jeho koncentraci protoze se meni pomer sinku zapricineneho procesy zive prirody a rozkladu ve stratosfere.

    TUHO: #uvaha

    optimistkej pohled: ten metan shori a nepujde do atmosfery, kde by byl jako 28-36x silnejsi sklenikovej plyn, zlikviduje se tak "casovana bomba"

    1Ch4 -》1co2 + ...

    A pesimistickej: metan by se za 4 roky rozpad. A samozrejme to shoreni lesa problemu taky moc nepomuze :)
