"Niisuguse arusaama juures ei saa me enam karistamatult langetada metsi ja kuivendada soid, rajada jõgedele paise ja killustada ökosüsteeme maanteedega, rajada kaevandusi ja puurida gaasikaeve. Kogid [Põhja-Kolumbias elav indiaanihõim, H.] ütlevad, et niimoodi tegutsemine kahjustab tervet looduse keha, samamoodi nagu see, kui raiuda inimesel maha mõni jäse või eemaldada mõni elund. Kõigi heaolu sõltub igaühe heaolust. Me ei saa langetada üht metsa siin ja istutada teist metsa seal, öeldes endale süsihappegaasi netokoguse arvutuse abil rahustuseks, et me ei ole mingit kahju tekitanud. Kuidas me teame, et me ei eemaldanud mõnd elundit? Kuidas me teame, et me ei ole hävitanud seda, mida kogid kutsuvad esuana'ks – otsustavaks sõlmeks loodust toestavas mustas ühendusniidis. Kuidas me teame, et me ei hävitanud püha puud, mida kogid kutsuvad "liigi isaks", millest kogu liik sõltub?" kirjutab Charles Eisenstein raamatus "Kliima: uus lugu", mis ilmus poolteist aastat tagasi nii Swedbanki kui Edmund Burke'i Seltsi raamatusarjas. "Süsinikutriangel on suitsukate põhiprobleemi varjamiseks," loen ma oma märkmetest Tähenduse teejuhtide 202. vestlusringist Indrek Vainu ja Madis Vasseriga, mille üheks lähtekohaks oligi Eisensteini eespool nimetatud raamat. Мa kirjutasin sellest jutuajamisest välja terve pinutäie enda jaoks uusi nimesid ja teoseid. Eelkõige jäid kõrva: 1) Jem Bendell "Deep Adaptation"; 2) William Catton "Overshoot: The Ecological Basis of Revolutionary Change"; 3) Michael Huesemann "Techno-Fix: Why Technology Won't Save Us or the Environment"; 4) Derrick Jensen, "Bright Green Lies: How the Environmental Movement Lost Its Way and What We Can Do About It (Politics of the Living)"; 5) A. J. Friedemann "When Trucks Stop Running: Energy and the Future of Transportation (SpringerBriefs in Energy)"; 6) Ugo Bardi "Before the Collapse: A Guide to the Other Side of Growth"; 7) John Michael Greer "Collapse Now and Avoid the Rush: The Best of The Archdruid Report". Vestluse lõpus tsiteerisin ma kokkuvõtteks enda suurt lemmikut USA süvaökoloogi David Abramit: "Kui me aga tõesti tunneme, et maailm sõltub meist ja meie tähelepanust, meie tänusõnadest ja kiidulaulust, siis omandab see juba teistsuguse tähenduse. Sellisel juhul on meil raske jõele tamm ehitada või metsad maha raiuda, sest me mõistame, et me peame tegutsema ja kõnelema nii, et me saavutaksime meid ümbritseva maailmaga parema kooskõla. See on väga erinev meelelaad ja selle meelelaadi süvakihid on tõepoolest poeetilised. Nendest saab vaid laulda ja luuletada. Ma ei räägi siin aga luuleraamatutest, riiulinurgale unustatud antoloogiatest, vaid elavast poeesiast. Me peame endale tunnistama oma animaalset kehalikkust, me ei ole kehatud vaimud, vaid kahe jala ja kahe käega füüsilised olendid. See tõsiasi peaks kajastuma ka meie kõnes. Me peaks hoiduma teoreetilisest ja abstraktsest žargoonist – keelest, mis on kaotanud igasuguse kontakti maaga, nii et selle juurtelt on langenud viimasedki liiva- ja mullaterad. Kahjuks on selle mandri ülikoolides asjad liikunud just vastupidises suunas". Kahju tõesti. Head uudistamist! H.

16.09.2022PC Earth for all – und was sie dafür tun können. Mensch Mahler am 16.09.2022 Earth for all – Teil 2. Wer wissen will, wie sich eine gute Zukunft realisieren lässt, kommt an »Earth for All« nicht vorbei.Der Club of Rome ist einer der bekanntesten Thinktanks der Welt. Er wurde 1968 gegründet und setzt sich für eine nachhaltige Zukunft ein. Dem Zusammenschluss von Expert*innen verschiedener Disziplinen aus mehr als 30 Ländern gehören u. a. Maja Göpel, Hans J. Schellnhuber und Ernst Ulrich von Weizsäcker an. Bekannt wurde die gemeinnützige Organisation durch den Bericht »Die Grenzen des Wachstums«, der über 30 Millionen Mal verkauft wurde. Im oekom verlag erschienen bislang sechs Reports an den Club of Rome, darunter »2052« von Jørgen Randers und »Der geplünderte Planet« von Ugo Bardi. Und nun, 50 Jahre nach den Grenzen des Wachstuns, das Buch des Club of Rome, das ich als 18jähriger politisch erwachter junger Erwachsener verschlungen habe, also Earth for all mit dem zum Teil identischen Forscherinnen Team wie damals. Mich hat es aufgerüttelt und mein gesamtes politisches Leben nachhaltig geprägt. Schon damals waren die Themen dieselben wie heute: Kli-maerwärmung, Gendergerechtigkeit, globale Armut des Südens, Gerechtigkeit für alle, Energiewende und nachhaltige regenerative Landwirtschaft. Ich wünsche dem Buch Earth for all die selbe durchschlagende Wirkung – nein, noch mehr, denn dieses Buch ist noch notwendiger wie die Grenzen des Wachstums. Möge es auch wieder eine ganze Generation weltweit wachrütteln. Das Zeug dazu hat es auf jeden Fall. Schlusssatz: Hat dieser Globus noch eine Chance? Das entscheiden Sie, wenn sie dieses Buch zuklappen und den nächsten Schritt tun.„Earth for all“, herausgegeben vom Club of Rome, 256 Seiten kosten 25 Euro, die die Welt – mindestens ihre Welt – verändern können.

Esattamente 50 anni fa nel 1972, Aurelio Peccei e il Club di Roma commissionano al MIT un rapporto che passerà alla storia con il nome de "I limiti dello sviluppo". Per la prima volta uno studio di quel livello certificò la finitezza delle risorse e la fine del sogno di una crescita infinita come vorrebbe il sistema capitalistico.Il Professore Ugo Bardi, membro del Club di Roma e autore di "Limits & Beyond", ci racconta come sia stato possibile realizzare uno studio tanto accurato, in grado di predire con incredibile precisione gli scenari odierni, caratterizzati da un sistema al collasso.✅ Ugo Bardihttps://ugobardi.blogspot.com/✅ Club di Romahttps://www.clubofrome.org/

Oggi è l'Earth Day, la giornata dedicata annualmente alla salvaguardia del nostro pianeta. Per questo vogliamo parlare di sviluppo sostenibile e lo facciamo con Enzo Savignano e Ugo Bardi che ci raccontano la storia e il presente del Club di Roma e del documento "I limiti dello sviluppo" che esattamente 50 anni fa fece molto scalpore e diede il via al dibattito sulla sostenibilità. Infine, con Karoline Rörig, parliamo di idee sostenibili tra Germania e Italia. Von Francesco Marzano.

Ugo Bardi is a Professor in Physical Chemistry at the University of Florence, and a member of the Club of Rome. Ugo’s work focuses on promoting a sustainable transition to renewable energy on the basis of a quantitative energy yield analysis. In his blog, he examines among other things the “Seneca Effect”, a biophysical interpretation of the collapse of complex systems.In this fascinating interview Ugo ranges from discussing what killed the dinosaurs to revealing a theory of evolution that could radically transform how we combat the climate crisis. He also provides details on some of the most exciting technological advancements which could help us navigate our energy, economic and ecological crises. This isn’t one to miss. Listen here or catch it on Apple or Spotify.Ugo’s blog, The Seneca Effect.You can also follow Planet: Critical on Youtube and support the project on Patreon where I upload a bonus video every Saturday.© 2022 Rachel Donald Get full access to Planet: Critical at www.planetcritical.com/subscribe

Warum gibt es eigentlich Leben auf diesem Planeten? Wie entsteht und erhält sich die Biosphäre, in der auch wir Menschen leben. Und könnte es sein, dass die Erde nicht nur Heimat aller Lebewesen ist, sondern ihrerseits wie ein Organismus funktioniert? Mit diesen Fragen hat sich der bekannte britische Naturwissenschaftler James Lovelock seit über 50 Jahren beschäftigt. Lovelock ist mit seiner sog. „Gaia-Hypothese“ einer der wichtigsten Vordenker der weltweiten Ökologiebewegung. Einige seiner zentralen Grundannahmen sind auch von der Fachwelt, z.B. in der Ökosystemforschung, aufgegriffen worden. Ugo Bardi, Professor in Florenz und Mitglied im Club of Rome, zeichnet in seinem Essay anschaulich die Entstehung und Entwicklung von Lovelocks Gaia-Hypothese nach und zeigt, wie hilfreich sie ist, um das Ökosystem der Erde besser zu verstehen – und besser zu schützen.

2021 comes in hot with Michael Dowd, ecumenical Christian preacher turned climate grief advocate, whose Post Doom Conversations are a well of wisdom for anyone prepared to stop fighting the inevitable* and start celebrating what actually can be done in these weird, scary, precious years to come. We discuss his time as an evolutionary biology evangelist and his friction with techno-optimists, what it means to live sustainably within a mature religion of place, urban scaling and collective action problems, a general theory for the collapse of market-based civilizations, and how to reorient one’s faith to planetary and secular values that allow us to accept reality as it is and avoid doing further evil to the Biosphere and each other. (*We spend a lot of time in this encounter digging underneath the surety to ask not “Is there hope,” but “Where am I still doomed by my conditioning?”)Please rate and review Future Fossils on Apple Podcasts!

This week is a watershed moment for Future Fossils Podcast: the show’s first guest host! My friend Kevin Arthur Wohlmut is an engineer who creates occasional one-shot podcasts of fiction and nonfiction, and (according to him) worries about the future too much. We met at InterPlanetary Festival last year on the visit that inspired me to move to Santa Fe, and ever since we’ve had a rich correspondence of mutual far-future fiction recommendations and armchair philosophy chats.Kevin sent me his very cool readings of two essays with the same name, each portraying very different version of “The Next Ten Billion Years,” and both so provocative I felt like sharing them here on the show’s main feed – with my own commentary at the end, on blind spots in imagining deep time and our own psychedelically weird future.You can find Kevin active in the Future Fossils discussion groups at Facebook and Patreon.Professor Ugo Bardi blogs at https://cassandralegacy.blogspot.com and http://chimeramyth.blogspot.com.

This week I am delighted to welcome back Ugo Bardi to the show. Ugo is Professor of Physical Chemistry at the University of Florence, and the man behind the Cassandras Legacy blog, where he writes about resource depletion, climate change, and renewable energy amongst other things. We discuss the recent drop in global C02 emissions and what it means for our global economic system, the hopes for a soft landing post peak-oil and coal, solar panels as our great saviour, and his thoughts on the likelihood of global demographic decline.

Un crollo di quasi il 40% in tre mesi: il prezzo del petrolio è sceso sotto i 70 dollari a barile. E' una delle cadute più precipitose degli ultimi anni. Perchè? Ugo Bardi, chimico fisico all'università di Firenze, racconta a Memos che il mercato e i prezzi del greggio si comportano un po' come il livello del mare prima di uno tsunami: «Si ritira, cioè i prezzi si abbassano, prima della tempesta». Quale sarebbe la tempesta in arrivo? «Il sistema – dice Bardi – non è in grado di sussistere a questi prezzi per un motivo molto semplice: una grande quantità di petrolio che si estrae oggi ha un costo elevato, di oltre 100 dollari al barile. E in un mercato con prezzi di circa 70 dollari nessuno può permettersi di vendere a lungo, rimettendoci». Cosa succede allora? «Che il prezzo non può stare per troppo tempo sui 70 dollari senza mandare in bancarotta una frazione consistente dei produttori di greggio». Ugo Bardi cura un blog (http://ugobardi.blogspot.it) che raccoglie analisi e studi sullo sfruttamento delle risorse e i cambiamenti climatici. Ospite a Memos oggi anche Alberto Negri, inviato speciale del Sole 24 Ore. «La causa del calo dei prezzi del greggio è un eccesso di offerta rispetto alla domanda – dice Negri –, un eccesso dovuto anche alla forte presenza sui mercati, superiore alle aspettative, di shale gas e shale oil. Ma la caduta dei prezzi è frutto anche e soprattutto di una scelta politica: l'Opec, e cioè l'Arabia Saudita, insieme agli Stati Uniti hanno deciso da tempo di inondare i mercati di petrolio. In questo modo tengono nel mirino l'economia russa e quella iraniana, legate all'export di greggio. E, com'è noto, Russia e Iran sono due nemici di Washington, ma anche di Riyad».

This week our guest is Dr Marco Raugei. Marco is a Senior Research Fellow at the Department of Mechanical Engineering and Mathematical Sciences, Oxford Brookes University (UK), and a Senior Researcher with the UNESCO Chair in Life Cycle and Climate Change of ESCI - Pompeu Fabra University in Barcelona (Spain). His main research interests are in theoretical improvements of existing approaches for environmental sustainability assessment, and the development of strategic energy supply scenarios, with special focus on photovoltaic (PV) technologies. He has also been actively contributing to the theoretical and methodological advancement of Emergy Synthesis, which looks at human-dominated processes and systems as parts of and ultimately supported by the larger system in which they are embedded, namely the global geo-biosphere. You can sometimes find his writings on Ugo Bardi’s blog: http://cassandralegacy.blogspot.co.uk/ We discuss his work on renewable energy, in particular his work on the current state of Photovoltaic or PV systems. We learn about the key differences between Energy Returned on Energy Invested and efficiency, bootstrapping fossil fuels to build a renewable future, re-organisation of our current economic system, and renewable energy’s storage problems. Enjoy!

This weeks guest is Ugo Bardi, Professor of Physical Chemistry at the University of Florence. He specialises in resource depletion, system dynamics modeling, climate science and renewable energy. He is also a member of the scientific committee of the Association for the Study of Peak Oil and Gas, or ASPO, is the president ASPO Italy, and a contributor to the Oil Drum, the best energy blog on the web. He is the author of several books, including "The Limits to Growth Revisited”, his upcoming book "Plundering The Planet", and even finds time to write his own excellent blog, Cassandra’s Legacy. Our discussion covers the role of volcano's, Georg Bauer, the father of mining, space aliens, and climate change. You can find his blogging work here: http://cassandralegacy.blogspot.co.uk/ http://theoildrum.com http://peakoil.net And here is where you can get a hold of his books: http://www.amazon.com/Limits-Growth-Revisited-SpringerBriefs-Analysis/dp/1441994157/ref=sr_1_1?s=books&ie=UTF8&qid=1360432828&sr=1-1&keywords=limits+to+growth+revisited Also, a few weeks ago, I was interviewed for a recent episode of Doug Lains dietsoap podcast, where we talk of Marx, Keynes, and money.
