    no ja nevim jak vy, ale jsem hrozne prekvapenej

    Tisíce Čechů by rády na svých domech využívaly fotovoltaiku, jenže nemohou.
    Kabely, elektrické rozvody či starší trafostanice nestačí na rekordní rozvoj obnovitelných zdrojů.
    Nárůst je v přepočtu na obyvatele několikrát pomalejší než v Polsku nebo v Rakousku.
    Zákon, který má problém řešit, má však řadu nevyjasněných otázek a jeho přijetí je v nedohlednu.
    Hrozí, že česká ekonomika nebude konkurenceschopná.

    TUHO: “The idea was developed in Britain in 2008 on the understanding that finance, the economy and the ecosystem are all tightly bound together. Protecting and restoring the ecosystem to balance cannot be undertaken effectively, we argued, without the transformation of the other sectors. Joined-up policies are needed. Financing the hugely costly overhaul of the economy away from its dependence on fossil fuels cannot be achieved without the subordination of the finance sector to the interests of society and the planet.”

    “Our report, published in July 2008, called for ‘joined-up policies to solve the triple crunch of the credit crisis, climate change and high oil prices’. It argued that

    the global economy is facing … a combination of a credit-fuelled financial crisis, accelerating climate change and soaring energy prices underpinned by an encroaching peak in oil production. These three overlapping events threaten to develop into a perfect storm, the like of which has not been seen since the Great Depression. To help prevent this from happening we are proposing a Green New Deal.”

    Adapt or die: Jem Bendell's radical vision to survive the climate crisis
    https://www.gq-magazine.co.uk/article/jem-bendell-deep-adaptation-climate-change-interview-2023

    The founder of the Deep Adaptation movement – which predicts that climate change will lead to nothing less than social collapse – has divided climate scientists and supercharged protest movements. Critics call him a doomsayer. Others say he’s the only one acknowledging the truth

    Numerous stations across Spain and Portugal shattered their all-time April temperature records today. +38.8 °C in Cordoba airport, Spain sets April's new national (and European) heat record! With +36.5 °C at Castro Verde, Portugal also set a new national record.

    V Severním moři by mohla vzniknout největší zelená elektrárna Evropy. Pobřežní státy v čele s Německem chystají obří energetický projekt, který by využíval větrnou energii. Takzvaných větrníků by tam mělo do roku 2050 stát tolik, že by měly dohromady sílu asi 150 jaderných elektráren v Temelíně a zajistí proud pro více než půlku evropských domácností.

    Větrná elektrárna silná jako 150 Temelínů. Devítka států chystá obří energetický projekt v Severním moři | iROZHLAS - spolehlivé zprávy
    https://www.irozhlas.cz/zpravy-svet/severni-more-vetrna-elektrarna-farma-evropa-projekt_2304251711_har

    Do konce desetiletí chce devítka zemí postavit v Severním moři tolik větrných elektráren, že by měly výkon 120 gigawattů a v polovině století už 300. Pro srovnání, jeden temelínský reaktor zvládne asi jeden gigawatt.

    Tím by se dala teoreticky zásobovat více než polovina evropských domácností.

    TUHO: jojo, to je dobrý pro další (detailnější) studium - ptal jsem se ho jestli a kdy byly v historii planety období, kdy teplota stoupala podobně rychle jak dnes ("similar increase")

    Yes, there have been instances in Earth's history where rapid increases in temperature occurred. For example, the Paleocene-Eocene Thermal Maximum (PETM) around 55.5 million years ago saw global warming exceeding pre-industrial temperatures by 4°C-8°C (IPCC_AR6_WGI_Chapter05, Page:42). However, the rate of temperature increase during these past events was generally slower than the projected anthropogenic climate change over this century (IPCC_AR6_WGI_Chapter01, Page:58). Other ancient hyperthermal events also occurred between 300 and 50 million years ago, triggered by the release of greenhouse gases (IPCC_AR6_WGII_Chapter03, Page:22).

    PETER_PAN: Ale potencial je porad diskutovanej adaptacne na klimatickou zmenu, ne jako nastroj managmentu ekosystemu s celoplanetarnimi dusledky na globalni ekosystemy.

    Porad tam je to to jakoze neco uspori, zlepsi, odolnejsi, lepe do dane lokality, mene externalit.
    Tohle jsou ale jen drobaky. To o cem ja mluvim je definice celych ekosystemovych modolu s globalnimi dopady. Treba zabraneni desertifikaci na rozsahlych uzemich, restaurovani koralovych utesu, vychytavani methanu v rostlinach co ho budou absorbovat a zpracovavat, .... mraky veci.

    TUHO: Ano a tim pres respekt k jejich praci take projevuju takhle nejakou kritiku.

    Je to jako kdyby byla zprava nejakych ucencu z tesne pred-moderni doby o stavu lidskeho zdravi. A z te zpravy by se na otazku "Is it surgery a solution for human diseases?" vypadlo neco jakoze urcite aspekty mozna jakoze trochu. Ano chirurgie nevyresi vschny problemy, ale je to hlavni pilir. A i kdyz srovnani s GMO/climate change mozna pokulhava tak jen proto, ze vliv je potencialne mnohem zasadnejsi nez uz chirurgie.

    PETER_PAN: No ale pak je otazka, jestli tvoje zklamani neprameni z prilisneho ocekavani od IPCC. IPCC je designovany v podstate jako resersni teleso - zjistuje to, co se deje v soucasnym vyzkumu a to syntetizuje a snazi se z toho delat shrnujici a pokud mozno kompletni vyzkumny zpravy. Jinymi slovy, ambice IPCC neni tak navrhovat "vlastni" reseni, ale shrnovat dostupny vyzkum o plodnych resenich. Ja diskuzi v tomhle poli moc neznam - ale asi je na miste otazka, jestli timhle smerem smeruje dostatek vyzkumu a je dobre komunikovanej nebo jestli tam je chyba na strane IPCC.

    WMO: Climate Change Continues to Shatter Records, Disrupt Human Society - CleanTechnica
    https://cleantechnica.com/2023/04/24/wmo-report-highlights-continuous-advance-of-climate-change/

    Concentrations of the three main greenhouse gases — carbon dioxide, methane, and nitrous oxide — reached record observed highs in 2021, the latest year for which consolidated global values are available (1984-2021). The annual increase in methane concentration from 2020 to 2021 was the highest on record. Real-time data from specific locations show levels of the three greenhouse gases continued to increase in 2022.

    ...

    Ocean acidification: CO2 reacts with seawater resulting in a decrease of pH referred to as “ocean acidification.” Ocean acidification threatens organisms and ecosystem services. The IPCC Sixth Assessment Report concluded that “There is very high confidence that open ocean surface pH is now the lowest it has been for at least 26 [thousand years] and current rates of pH change are unprecedented since at least that time.”

    ...

    Record breaking rain in July and August led to extensive flooding in Pakistan. There were over 1700 deaths, and 33 million people were affected, while almost 8 million people were displaced. Total damage and economic losses were assessed at US$ 30 billion. July (181% above normal) and August (243% above normal) were each the wettest on record nationally.

    ...

    Record breaking heatwaves affected Europe during the summer. In some areas, extreme heat was coupled with exceptionally dry conditions. Excess deaths associated with the heat in Europe exceeded 15,000 in total across Spain, Germany, the UK, France, and Portugal.

    TUHO: Prubirsky kamen:

    Is it GMO a solution for climate change?

    According to the IPCC AR6 report, genetic improvements through modern biotechnology have the potential to increase climate resilience in food production systems with high confidence. However, technical, agroecosystem, socioeconomic, and political variables strongly influence and limit the uptake of climate resilient crops, particularly for smallholders with medium confidence. While biotechnology can be used as an adaptation strategy, there is low confidence that genetically modified (GM) crops can increase food security and nutrition in smallholder farming systems relative to alternative agronomic strategies. Therefore, it is not clear whether GMOs are a solution for climate change. (IPCC_AR6_WGII_Chapter05, IPCC_AR6_WGII_TechnicalSummary)

    Takze pokavad je ten AI comprehensive tak jinymi slovy to IPCC vubec systemove neresi kdyz to komunikuje jen jako "potential to increase climate resilience". Smutny.
