    ILUSTRACE TOHO, JAK JE TO CELÉ VÍCE KOMPLIKOVANÉ, NEŽ SI VĚTŠINOU MYSLÍME

    Potlačení emisí z lodní přepravy paradoxně urychlilo globální oteplování - Ekolist.cz

    (...) S platností od 1. ledna 2020 už nesměla být v lodní dopravě používána paliva s obsahem síry 3,5 %, jak bývalo dříve zvykem, ale jen paliva s limitem do 0,5 %. Většina velkých námořních přepravců na to zareagovala v dostatečném v předstihu. Tím, že své lodě vybavovaly tzv. scrubbery, zařízeními pro předčištění paliv, případně skutečně přecházely na nízkosirné topné oleje. Podstatné je, že efekt tohoto opatření byl nad očekávání rychle patrný. Nad oceány se emise síry snížily o 80-90 % (v porovnání se stavem o pět let dříve)

    (...) Imise síry a jejich aerosoly přispívaly ke zvyšování albeda (schopnosti odrážet světelné záření), a tak paradoxně brzdily globální oteplování. Snižovaly onu průměrnou teplotu – velmi přibližně – o 0,5 stupně Celsia. Většina tepelných zisků planety, okolo 89 %, je absorbována oceány. Poté, co se ovzduší nad oceány díky zákazu vysocesirných paliv pročistilo, dostavil se i náležitý výsledek. Rychlý nárůst teploty.

    Jinak řečeno: rozsáhlé oblasti oceánů, ty s frekventovanou lodní přepravou, byly po desetiletí „ochlazovány“ díky emisím oxidů síry. Přesněji tedy díky jejich sirným aerosolům a reakcím mezi těmito aerosoly a mraky. Rozptylovaly sluneční záření dopadající z vesmíru, ovlivňovaly vznik kondenzačních jader mraků, zvyšovaly oblačnost a také její vytrvalost, stálost.

    Emise síry ovlivňovaly regionální i globální albedo. Bez nich přišla významná část ze 71 % planetárního povrchu – oblasti překryté hladinou moří a oceánů – o svůj tepelný štít. „Globální oteplování je především oteplování oceánů,“ shrnuje to Simons. „A to je jeden z důvodů, proč snížení emisí síry z lodní dopravy o 80 procent tak výrazně zvyšuje globální oteplování.“

    Robotic herding could open up vast areas of land to restoration efforts using both domestic livestock and/or wild ruminates. The precision we could gain would be extraordinary. At present to gain this level of precision we need to further carve up and subdivide properties with electric fences which just add one more barrier to not targeted wildlife, not to mention expensive human labor in setting up and taking down these fences daily.

    "In the next decade or so, we may see livestock producers working alongside engineers and computer scientists," McGee added. "Jobs in the industry's future will likely be very different from the ones we have today with increased adoption of precision livestock management."

    While the end goal of autonomous herding lies on the horizon, these scientists see their work as building the foundation—the rules of the road—for the successful deployment of existing robotics technology in a livestock setting.

    The Coming Tsunami of Grief | Kevin Hester
    https://kevinhester.live/2017/01/20/the-coming-tsunami-of-grief/

    As runaway abrupt climate change and it’s brutal reality bares down on us with the speed of a tsunami, another little discussed side affect is grief. I shall try to cover it in this blog and provide some avenues for readers to seek solace and solidarity below.

    CACOR: The Big Picture: Beyond Hope and Fear - Michael Dowd

    52-minute presentation delivered via Zoom on May 3, 2023 to the Canadian Association for the Club of Rome (CACOR) to be my most important and emotionally supportive video to-date.

    DESCRIPTION: No one needs convincing that we are living in an age of chaos and breakdowns. Even those without benefit of an ecological understanding of history feel the stress. How do we cope? How can we escape the seesaw of hope and fear? And, crucially, how can we be of support to others who are confused, angry, depressed, or filled with fear, blame, or guilt?

    There's interannual natural variability so the temperature is sure to come back below 1.5C in a number of subsequent years.

    1.5C in one year is beyond catastrophic. But what's most important is the sustained *average* temperature over multiple years.

    Since 2016 we've been in a 1.2C average temperature regime (climate).

    We might be headed, practically overnight, into a 1.5C climate. This is a paradigm shift from where we are now.

    Even 1.4C, probably the minimum we can reasonably hope for, would be a paradigm shift.

    This El Nino is by far the most significant and destructive event to ever hit our civilisation and that includes WW2. Due to Earth's Energy imbalance, once the average temperature goes up it won't come back down. These step-changes in Earth's climate can never be reversed.

    If you want evidence of the capture of the expert class, look no further than the ridiculous assertion that 20 years will be needed before being able to declare the 1.5C threshold broken. When the time comes people will know whether it's been broken because it will be obvious. An average over several years is enough

    Global warming set to break key 1.5C limit for first time - BBC News
    https://www.bbc.com/news/science-environment-65602293?at_medium=RSS&at_campaign=KARANGA

    Our overheating world is likely to break a key temperature limit for the first time over the next few years, scientists predict.
    Researchers say there's now a 66% chance we will pass the 1.5C global warming threshold between now and 2027.

    The chances are rising due to emissions from human activities and a change in weather patterns expected this ummer.
    If the world passes the limit, scientists stress the breach, while worrying, will likely be temporary.

    Hitting the threshold would mean the world is 1.5C warmer than it was during the second half of the 19th Century, before fossil fuel emissions from industrialisation really began to ramp up.

    The 1.5C figure has become a symbol of global climate change negotiations. Countries agreed to "pursue efforts" to limit global temperature rises to 1.5C under the 2015 Paris agreement.
