    A pokracovani. Carbon Brief o novem reportu

    Another key talking point to emerge from AR6 has been the question of when the world is expected to reach 1.5C and 2C of global warming.
    This article looks at what exactly the new report says on this topic and how it compares to previous estimates by Carbon Brief and from the IPCC’s 1.5C report.

    Dalsi clanek Carbon brief o AR6. Tentokrat o souvislostech otepleni s extremnim pocasim...

    This piece examines what the Intergovernmental Panel on Climate Change’s (IPCC) sixth assessment report (AR6) says about the link between climate change and extreme weather.
    AR6 says it is “established fact” that human-caused greenhouse gas emissions have “led to an increased frequency and/or intensity of some weather and climate extremes since pre-industrial times” and this explainer looks at what this means for different weather events, including flooding, drought and tropical cyclones.

    TLDR: "Golfský proud (nejen) - the end is near"

    Almost all the non-linearly detrended sea surface temperature (SST)-
    and salinity-based Atlantic Meridional Overturning Circulation (AMOC
    indices show highly significant increases in the three considered EWS
    indicators, providing evidence that the AMOC is approaching a
    bifurcation-induced transition. Statistical sig-
    nificance of positive trends is determined from a test based on
    phase surrogates that preserve both variance and autocorrelation
    , and the results are not sensitive to changing the size of
    the sliding windows. The possibility
    of false alarms due to rising variance or AC1 of the high-frequency
    forcing can be ruled out since the corrected restoring rate λ has been
    considered here.
    ...
    As expected for a system approaching
    a bifurcation-induced transition, the time evolution of the restoring
    rate λ is strongly correlated with the inverse of the estimated model
    sensitivity dx*/dt, which provides strong evidence that the AMOC is
    indeed approaching a critical, bifurcation-induced transition.
    ...
    these findings still raise
    concern regarding whether state-of-the-art climate models would
    be skilful in predicting a forthcoming AMOC collapse. This is in
    agreement with previous results showing that the present AMOC
    mode is too stable in state-of-the-art models9, most likely due to an
    underestimation of the freshwater export from the northern Atlantic
    Ocean, caused by errors in the salinity fields and insufficient model
    resolution12. The high-resolution, eddy-permitting HadGEM3-GC2
    model, which was used to establish the suitability of the SST-based
    AMOC indices employed here51, constitutes a major step forward
    concerning a more accurate representation of the AMOC and its
    stability
    ...
    The results presented here hence show that the recently discov-
    ered AMOC decline during the last decades is not just a fluctuation
    related to low-frequency climate variability or a linear response to
    increasing temperatures. Rather, the presented findings suggest that
    this decline may be associated with an almost complete loss of sta-
    bility of the AMOC over the course of the last century, and that the
    AMOC could be close to a critical transition to its weak circulation
    mode.

    TUHO: The “crucial decade” was 2010-20, as we were told at the time, not the 2020’s. The 2020’s will be the decade of consequences. Like the people who understood the real nature of the Nazi project in the 1930’s and took in the Jews during World War Two, those that overcome these states of denial, and act in response to the real nature of the world today, are not predominately part of either the Left or Right, or of a particular religious or cultural group. What they have in common is what Tim Snyder, author of “Black Earth, Holocaust as History and Warning” calls “self knowledge”: the personality structure that is able to overcome the pressure to conform to the herd, and the ethical inability to stand by as society descends into evil.

    In the next two to three years the prevention of humanity’s greatest hell of rape, slaughter, and starvation will depend on whether this small group of people around the world go into active and unlimited nonviolent resistance against the carbon regimes. These people already know who they are.

    Smoke from raging forest fires in Siberia has reached the north pole for the first time in recorded history, as a Russian monitoring institute warned the blazes were worsening.
    Devastating wildfires have ripped across Siberia with increasing regularity over the past few years, which Russia’s weather officials and environmentalists have linked to climate change and an underfunded forest service.

    TUHO: takhle, jsem skeptický k řadě poliických představ souvisejících s klimatickou změnou... ale carbon removal je prostě čistý nesmysl. To už jsem optimističtější ohledně nějakých průlomových technologií, které by emise dokázaly snížit daleko razantněji... ale carbon removal nad rámec absorbce ekosystémem je prostě nesmysl (nejspíš mi ještě přijdou v mezích zdravého rozumu takové ty nápady jako hnojení oceánů železem, apod.... sice je potřeba promyslet důsledky, ale nastartovat fotosyntézu tam, kde pro ní zatím nebyly podmínky by byl asi nejpřiměřenější a nejrealističtější pozitivní civilizační feedback... u jiných věcí si prostě neumím představit, že čistá stopa technologií absorbce oxidu uhličitého by mohla být negativní... nejde jen o tu energii, ale i o vše okolo)

    Nakonec ještě dojde na moje slova, že nejbezprostřednějším krokem bude lakování asfaltu a střech nabílo.... je to zdaleka nejlevnější geoinženýring, a navíc poměrně low-tech a masově proveditelný (dokonce guerillově). Při těch teplotách jako v Řecku je to dokonce hodně aktuální...

    The UN’s long-awaited climate report, released on Monday, offered a stark reminder that removing massive amounts of carbon dioxide from the atmosphere will be essential to prevent the gravest dangers of global warming. But it also underscored that the necessary technologies barely exist—and will be tremendously difficult to deploy.
    Global temperatures will continue to rise through midcentury no matter what we do at this point, according to the first installment of the Intergovernmental Panel on Climate Change’s sixth assessment report. How much hotter it gets, however, will depend on how rapidly we cut emissions and how quickly we scale up ways of sucking carbon dioxide out of the air.
    Climate scientists say we’ll need to do carbon removal, in part, to balance out the emissions sources we still don’t know how to eliminate or clean up, like flights and fertilizer. The other, more ominous reason is we may well need to pull the planet back after it blows through dangerous temperature thresholds.

    The IPCC 6th Assessment Report features a new emissions scenario – SSP1-1.9 – limiting warming to 1.5C in 2100 with limited overshoot. It requires the world reach net-zero by 2055.
    However, under the hood it assumes a huge amount of negative emissions over the 21st century.
    The assessed "carbon budget" to limit warming to 1.5C in the IPCC report is around 500 GtCO2.
    However, the SSP1-1.9 scenario emits 700 GtCO2 during the 21st century, blowing way past the remaining carbon budget. At the same time, it deploys 430 GtCO2 of negative emissions.
    Relying on negative emissions allows the scenario to have a more plausible emissions reductions pathway; a similar scenario not using any net-negative emissions would likely require getting to global net-zero emissions in the 2040s.
    However, the technologies to do this are still largely untested at anything close to the scales required. We are essentially betting that we can get back to 1.5C through planetary-scale engineering late in the century after overshooting the target.
    Data on the positive and negative emissions assumed in various scenarios can be found in the SSP database:

    welcome to the future

    Jeho dceři Irini tekly slzy, když líčila, jak utekla, aniž by věděla, co se stalo s jejím otcem. Nevěděla ani, zda byl zničen dům, který s otcem její rodina sdílí. „Pokud by otec nezůstal, náš dům by shořel,“ řekla. „Hasiči nikde nebyli. Naštěstí tu byli dobrovolníci,“ dodala. „Cítím hněv, nic jiného.“

    Snímky ze sociálních sítí zobrazující vyčerpané hasiče spící na zemi, stále oblečené v kouřem zašpiněných uniformách, ukazovaly, pod jakým náporem se řecké záchranné složky ocitly.

    „V březnu jsme měli deset dní záplav, pak sníh. Na aténském předměstí Varympompi a na ostrově Euboia budeme dvacet dní s pěti sty hasiči. Teploty byly v raných fázích požáru Varympompi minulý týden tak vysoké, že se voda vypařila, než stihla z hasičského letadla dopadnout na plameny,“ dodal.
