Wenn damit kein Geld zu verdienen ist
Heute morgen brachte der #WDR5 https://www1.wdr.de/mediathek/audio/wdr5/wdr5-toene-texte-bilder-medienschelte/index.html einen Hinweis auf die Möchtegernkonkurrenz zur #Wikipedia.#ElonMusk hat in seinem Werkzeugkasten jetzt auch eine #Suchmaschine, die auf seinem KI-Chatbot #Grok basiert. Sie heißt sinnigerweise #Grokipedia und soll wohl die Stimme ihres Herrn sein https://www.heise.de/news/Kontroverse-Themen-KI-Modell-Grok-konsultiert-offenbar-Elon-Musks-Aeusserungen-10483586.html . Gleich dazugesagt wurde, daß sie eine Schräglage bei einigen Themen wie beim Komplex #Klimawandel habe.
Sofort probiert: https://grokipedia.com/page/Climate_changeDa stehen nüchterne Aussagen wie "Global temperatures have risen by approximately 1.1°C since pre-industrial times, leading to observable shifts in ecosystems, including poleward migrations of species ranges in terrestrial and marine environments" und "Scientific literature reflects a strong consensus, with over 99% of peer-reviewed studies endorsing a substantial human role in recent warming" als auch relativierende wie "overestimated tropospheric warming rates compared to satellite observations".
Die Suche nach einem Artikel über Stefan #Rahmstorf lieferte nichts.
Über den Namen #BjørnLomborg bin ich beim Querlesen aber gleich mehrfach gestolpert.
https://de.wikipedia.org/wiki/Bj%C3%B8rn_Lomborg
Lomborg hat eine schillernde Vergangenheit von Greenpeacemitgliedschaft über Klimawandelrelativierung bis zu seiner Berühmtheit für kühle Aussagen zu #Kosten und #Nutzen - von #Klimaschutzmaßnahmen versus Anpassung an die #Klimawandelfolgen durch #Innovationen und #Wirtschaftswachstum.
"So, what is the way forward? First, Lomborg argues, we need to evaluate climate policy in the same way that we evaluate every other policy: in terms of costs and benefits."
https://lomborg.com/false-alarmDas klingt irgendwie nach dem Denken heutiger #Politiker wie #KatherinaReiche.
"Bundeswirtschaftsministerin Katherina Reiche (CDU) hat einen flexibleren Umgang mit den Klimazielen gefordert. „Wenn Klimaschutz so organisiert ist, dass damit kein Geld zu verdienen ist (…), dann geht das in die falsche Richtung“, sagte die Ministerin auf dem „Tag der Industrie“ in Berlin."
https://www.welt.de/wirtschaft/article256301048/Tag-der-Industrie-Und-dann-stellt-die-neue-Wirtschaftsministerin-Reiche-das-Klimaziel-2045-infrage.htmlWird Grokipedia auch in Deutschland als Wissensquelle genutzt, oder reicht Wikipedia für einen ersten Überblick?

More on Bananas from North Atlantic in 2023, here by #MattEngland, Stefan #Rahmstorf et al

Low surface wind speed led to shallower-than-normal ocean mixing which enabled heating the surface more.
Less clouds from shipping SO2 were only marginally responsible and only in small pockets.Okay. But where did the wind go?
Surface wind is impacted by jetstream. And I think, the jetstream got diverted in June and July 2023 to Northern Greenland. Due to low spring snow cover in Eastern Canada which led to dry soil – which in turn gets hotter than wet soil.

A new paper on #AMOC
Prose summary by the authors https://theconversation.com/meltwater-from-greenland-and-the-arctic-is-weakening-ocean-circulation-speeding-up-warming-down-south-238302
actual paper https://www.nature.com/articles/s41561-024-01568-1 #Pontes et al 2024
tldr: by adjusting #Greenland meltrate to actually observed accelerated rate which is underestimated in standard climate models, they are now able to explain the observed increase in SST and salinity in the South #Atlantic with a slowdown of the AMOC in the past decades , matching the slowdown rate calculated by #Rahmstorf 's former PhD student #Caesar 2018.
If you recall, that's the latitude in the S-Atlantic that #vanWesten etal 2024 found as prime location for early warning signal of an imminent AMOC collapse in their freshwater experiment.By applying melt (but without the observed AND projected acceleration that #Greene et al 2024 notify us of https://www.nature.com/articles/s41586-023-06863-2 ), Pontes' model now projects a total slowdown of 30% by 2040.
(Also noteworthy maybe that the authors pull the 2degree milestone forward to 2040, while some papers I read in 2018 still saw 2C sometime in the 2050s. But they're not the first researchers doing so that I came across.)Meltrate in Greenland is 30Mt of ice per hour... Did you know that 1kg of pizza equals 19kg CO2 which ultimately melts 12.3 t glacial ice?
1 cup of coffee is 400gr CO2 and melts 260 kg. (sources see #2)Meanwhile, #COP29 news falsely report a global consensus in coal phase-out. A journalist on Bluesky dug into the actual agreement and the countries listed.
First, it's not a global agreement.
Then either, the countries have no coal energy, or they have already long ago planned the phaseout so nothing new from them, either.
The single country with a new development in this coal agreement is Australia which announced to close 3 coal power plants ... sometime in the future... -

Trouble is brewing in the North Atlantic.
'We don't really consider it low probability anymore':
Collapse of key Atlantic current could have catastrophic impacts, says oceanographer Stefan Rahmstorf
The Atlantic Ocean's most vital ocean current is showing troubling signs of reaching a disastrous tipping point.
Oceanographer Stefan Rahmstorf tells Live Science what the impacts could be.
Beneath the waves, the Atlantic Meridional Overturning Circulation ( #AMOC ),
which includes the Gulf Stream,
acts as a planetary conveyor belt bringing nutrients, oxygen and heat north from tropical waters,
while moving colder water south
— a balancing act that keeps the Northern Hemisphere warm.But research into Earth's climate history shows that the current has switched off in the past,
and a growing number of studies suggest that climate change is causing the AMOC to slow, possibly leading it toward a disastrous collapse.On Monday (Oct. 21), 44 oceanographers from 15 countries published an open letter calling for urgent action in the face of the weakening circulation.
They warn that the risk of collapse has been "greatly underestimated" and will have "devastating and irreversible impacts" for the world.Live Science sat down with the letter's lead organizer, #Stefan #Rahmstorf, an oceanographer who runs the Earth system analysis department at the Potsdam Institute for Climate Impact Research in Germany, to discuss the AMOC developments and their potential global effects.

Brand new 52min documentary on #ClimateTippingPoints with
#Rockström, #Rahmstorf, @weatherwest #Swain and a few others.
https://www.youtube.com/watch?v=U8pLrRkqbb0The scientists speak a little into the camera, then the filmmaker either illustrates the spoken words with aerial nature scenes or with clear, animated graphics.
English with English subtitles. I like it!Again, the 7%-water-rule comes up.
Eye opener: 7% at +1.5C is more water vapour than what 7% was at +1C. Same principle as in how the rich get richer faster.Not answered: most land mass has more than +1C, Germany in summer can be +3C, places in the Adriatic sea +5C this August.
So do we apply the 7%-rule to the local deviation from the normal in order to express or to guage the water hunger of the air in this particular parcel?
And also, what happens when the wind drives one parcel away after it drank its fill from soil, plants, water bodies, and a new parcel comes in, heats up to the local deviation, drinks its fill, and moves. I mean, shouldn't the inner continents be all dried up by now?
Or maybe the act of evaporation cools the place enough for a new parcel that moves in, to be sufficiently shocked into raining down what it had sucked up elsewhere...hm.
Anyway. Good documentary! -
An interview by #JonathanWatts with #Rahmstorf on his assessment of the AMOC situation.
Nothing new if you follow Rahmstorf. But I'd like to point out this bit: " Some colleagues say we shouldn’t talk about extreme possibilities like an Amoc collapse because it sounds alarmist and might distract people from more certain impacts of global heating "
because it is reminiscent of the outrageous NYTimes event 4 weeks ago where David Wallace-Wells had Rahmstorf on stage with Michael Oppenheimer.
Oppenheimer is an anti-alarmist. And acc to his Wiki article, he shaped the US interface between politics and science since the acid rain issue. Interface = read "filter".So he is a major reason why the US has not done anything in the past 30 years. And due to huge influence on multi-state bodies like OECD, G7, IMF, World Bank, Oppenheimer is also co-responsible for their failure.
On stage, Oppenheimer said exactly that which Rahmstorf alludes to in the Guardian interview: "Let's not talk about AMOC at all. No politician can hang his hat on those uncertainties. Let's focus adaptation instead!"
Oppenheimer was not corrected by Wallace-Wells. Typical NYTImes failure.
But what do you suggest to adapt to, Oppenheimer? A warming world, a super-heating world, or one with a collapsed AMOC?
And do politicians "hang their hat on" nuclear plants or bridges being built with a 50% risk of a major catastrophe?Arrogant, smug Dunning-Kruger ass. <shudders>
I feel, the interview in the Guardian is a direct response to that event.
But it isn't really. The interview is part of the news cycle of the letter from 44 Scientists to the governments of the #ArcticCouncil .I posted about the NYTimes event in the previous toots ⤴️

Guter Podcast zum Cold Blob und AMOC https://www.ardaudiothek.de/episode/iq-wissenschaft-und-forschung/raetselhafte-kaelteblase-geraet-der-subpolarwirbel-aus-dem-takt/bayern-2/13795411/
Mit #Rahmstorf, eh klar, aber noch eine Forscherin ist dabei, die speziell Interessantes erzählt.
Hab wieder was dazu gelernt.
Zum Beispiel ziemlich am Anfang, zum Subpolaren Wirbel, wie der überhaupt entsteht.
Durch Wind!
Der treibt das warme Golfstromwasser auf der Höhe New Yorks nach Osten. Und dort gibt es dann irgendwo so eine Art Kreuzung, wo der Wind nach Norden oder weiter nach Osten geht.
Wenn er nach Norden geht, treibt er damit auch den Wirbel an.
Und dann weht er auch mal vo Ost nach West... im Winter wohl..
Im Filmchen sieht man die v-Wind Komponente in den Wintermonaten. V-Wind ist rot, wenn der Wind nach Norden weht. Und blau, wenn er nach Süden weht. Daten: https://climatereanalyzer.org/research_tools/monthly_maps/Der Subpolar Gyre / Cold Blob ist auch nich immer an derselben Stelle, fest eingemauert oder so. Nee! Das wabert alles so fuzzy rum, mal mehr rechts und mal mehr links.
Und je nachdem ob mehr rechts oder mehr links, gibt es in Zentraleuropa starke Hitze.Muss auch gucken, dass ich ein paper von ihr finde. Vll steht ja in der "Introduction" noch mehr Interessantes um Subpolar Gyre drin.

Eyesore alarm 😁
AMOC Figure 1A from #ReneVanWesten et al 2024 https://www.science.org/doi/10.1126/sciadv.adk1189 depicts the fictional, modelled AMOC in a pre-industrial environment with only freshwater added continuously.
I took the liberty to superimpose a chart on it with AMOC proxy data from #Thornalley 2018 and #Rahmstorf 2015.
All three were "produced" in a pre-industrial world. But Rahmstorf's and Thornalley's AMOC comprise the effects of greenhouse gases #GHG and land-use change #LUC, and all that comes with them.I'm just sharing it for , dunno, well, to share the shock. The similarity had struck me when I saw vanWesten's chart and recalled the one from Thornalley. It has a peak early on, just like the computed model, and races downhill approximately after the same amount of years as the model run. It also has a slow decline before the cliff like the model but I can't make that visible, somehow.
Data for Thornalley and Rahmstorf can be found in Caesar 2021's data repository https://github.com/ncahill89/AMOC-Analysis -

Hey @MurmeltHier
habe die 18 Seiten nun durch. Wie schon erwähnt, werden es die "richtigen" Adressaten nicht lesen.
Was mir immer wieder ins Gedächtnis kommt, sind Olaaf #Scholz seine herablassenden Interviews mit Klimaaktivisten.
Das, was die beiden Hungerstreikler #Jeschke & #Bonasera Nov2021 dem Scholz sagten, ist in dem Kapitel von #Rahmstorf sehr anschaulich beschrieben.
Das katastrophale Verfehlen der 1,5°C-Marke werden die beteiligten Entscheider noch mitbekommen.
