    Maji vedci nejakou predstavu, co se stane s klimatem ve stredni Evrope, kdyz zkolabuje AMOC, ale zaroven pobezi dal oteplovani? Nabyl jsem dojmu ze konsensus je, ze se ocekava otepleni u nas do konce stoleti o asi celkem 4-6C, je to tak? Takze pokud by mel AMOC ochladit Evropu o 8-10C, je mozne, ze se to nejak vicemene vyrusi?

    Important preprint: https://arxiv.org/html/2406.11738v1

    1. The authors identified where the #AMOC tipping point is in a state-of-the-art climate model.
    2. They identified what are observable & robust precursor signs before tipping in the model.
    3. They looked for such warning signs in real ocean data.
    4. They found signs that the AMOC tipping point will likely be crossed around mid-century.

    Note that the tipping point is where the AMOC collapse starts; it will then take decades to a century until it’s complete.

    They found that the critical place to look for warning signs is in the South Atlantic at the latitude 34 South (the tip of South Africa). I first suggested this in a 1996 paper based on theoretical considerations.

    DZODZO: a ten oxid uhličitý, kterej ta helikoptéra vypustila, ovšem zůstal v atmosféře obíhat neodbouranej doteď (v průměru, lze doložit průběžnou změnou poměru izotopů uhlíku v tom CO2 v průběhu času)

    dufam ze pri patku mozem jeden historicky offtopic k preprave vrtulnikmi, helikoptera nahradila 150 nosicov ale bolo to v dobe ked bolo este v tatrach kopu snehu :)

    jenže to není úplně pravda: vytářet sekty, bubliny a pyramidové hry je lidské. Ve skutečnosti je těžké najít nějakou ekonomickou aktivitu, která ve své podstatě není pyramidové schéma - stačí se jen pozorně koukat

    ten proof of work (zbytečný! stačí si představit atomické wallety, s jediným nedělitelným coinem, které by znemožňovaly double spending) a uhlíková stopa je to, co BTC dělí od běžné sekty a běžné pyramidové hry. Haré Kršna se svým vegetariánstvím jsou proti tomu úplne škodná sekta... Hare bitcoin, Bitcoin hare to prostě přehnali...

    Fire-Breathing Smoke Storms Punch High Into the Atmosphere | Discover Magazine

    As is evident from the image above and others that follow, these pyrocumulonimbus clouds, or pyroCbs, offer a visually dramatic reminder of just how extreme wildfire behavior can get. But they are significant for other reasons as well.

    PyroCbs can hurl barrages of lightning bolts to the ground, triggering even more wildfires. They also can help spread harmful particulate pollution far and wide, and even drive smoke into the stratosphere, five to seven miles above Earth's surface. Here, the smoke can actually influence the global climate, recent research has shown.

    ...

    It has long been known that pyrocumulonimbus clouds rise up from volcanic eruptions and nuclear explosions. But the first scientific confirmation of a pyroCb erupting from a wildfire didn't come until the year 2000.

    As the climate has warmed, and wildfire activity has intensified, pyroCbs have grown larger and more frequent, with record-breaking events in 2017, 2019, 2020 and 2021. In that latter year, an early and unusually warm fire season produced particularly scary pyroCb outbreaks.

    On July 16 of that year, an astonishing 10 pyroCbs blew up along the Saskatchewan-Manitoba border in Canada. Up until that point, this was a greater number than scientists had ever observed in North America on a single day since satellite tracking began in 2013, according to NASA.

    The outbreak came just two weeks after a monster pyroCb astonished scientists. It happened as a storm cell grew above a wildfire in British Columbia and spread across more than 62,000 square miles. That's an area slightly larger than the state of Georgia. This gargantuan cloud propelled a chimney of smoke into the stratosphere, as high as 10 miles up.
    ...
    The North American Lightning Detection Network recorded nearly 113,000 cloud-to-ground lightning strokes during the event, a large amount for a storm in Canada," according to NASA. "One meteorologist calculated that this one pyroCb event produced about 5 percent of Canada’s total annual lightning all at once."
