Several factors influence climate, such as physical factors like planet landscapes, economic and social factors and how human activity is organised. When studying climate, we need an interdisciplinary approach that brings together scientists, politicians, and policymakers. In these videos Ilaria Perissi, Global Sustainability Institute at Anglia Ruskin University, will discuss the main factors which trigger climate change and how her work as a science modeller can help policymakers in planning a more sustainable future.</div><div><br /></div><div><a href="https://www.aru.ac.uk/community-engagement/cambridge-festival/how-climate-science-models-can-help-policymakers-plan-a-more-sustainable-future">Ilaria Perissi - Cambridge Festival 2023 - Models and Climate Change</a></div><div><br /><div class="separator" style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhK7jF0mcdlasEdGlv7N_8aXw8HceJMinTrb2ItaU4PFShxpsbnFpQcGLwXX3ne3JaBiJHU64LnJzfXbJvbOp5Rqx28SpiDxvG38qGKgcxXMPCd8ilXek2pelhO_GalD2arsFUT_P3L0W9x0u4-RQVM2pOWyDkoZ-TxuJzox4I0GAorXwIUKgq7mVqeSA/s512/Immagine12.jpg" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="463" data-original-width="512" height="289" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhK7jF0mcdlasEdGlv7N_8aXw8HceJMinTrb2ItaU4PFShxpsbnFpQcGLwXX3ne3JaBiJHU64LnJzfXbJvbOp5Rqx28SpiDxvG38qGKgcxXMPCd8ilXek2pelhO_GalD2arsFUT_P3L0W9x0u4-RQVM2pOWyDkoZ-TxuJzox4I0GAorXwIUKgq7mVqeSA/s320/Immagine12.jpg" width="320" /></a></div><br /></div>Ilaria Perissihttp://www.blogger.com/profile/01813626341487097669noreply@blogger.com0tag:blogger.com,1999:blog-300324375078004462.post-29147074963437816812021-08-30T23:13:00.004+02:002021-08-30T23:16:05.892+02:00Live - Presentazione "Il Mare Svuotato" di Ilaria Perissi e Ugo Bardi co...<iframe frameborder="0" height="270" src="https://youtube.com/embed/ULkaeUPpyLA" style="background-image: url(https://i.ytimg.com/vi/ULkaeUPpyLA/hqdefault.jpg);" width="480"></iframe><div><br /></div><div><div class="style-scope ytd-watch-flexy" id="meta" style="background: rgb(249, 249, 249); border: 0px; font-family: Roboto, Arial, sans-serif; margin: 0px; padding: 0px;"><div class="style-scope ytd-watch-flexy" id="meta-contents" style="background: transparent; border: 0px; margin: 0px; padding: 0px;"><ytd-video-secondary-info-renderer class="style-scope ytd-watch-flexy" style="border-bottom: 1px solid var(--yt-spec-10-percent-layer); display: block; margin-bottom: 24px; padding-bottom: 16px;"><div class="style-scope ytd-video-secondary-info-renderer" id="container" style="background: transparent; border: 0px; margin: 0px; padding: 0px;"><ytd-expander class="style-scope ytd-video-secondary-info-renderer" style="--ytd-expander-collapsed-height: 60px; display: block; font-size: var(--ytd-user-comment_-_font-size); font-weight: var(--ytd-user-comment_-_font-weight); letter-spacing: var(--ytd-user-comment_-_letter-spacing); line-height: var(--ytd-user-comment_-_line-height); margin-left: 64px;"><div class="style-scope ytd-expander" id="content" style="background: transparent; border: 0px; margin: 0px; min-width: 0px; overflow-wrap: break-word; padding: 0px;"><div class="style-scope ytd-video-secondary-info-renderer" id="description" slot="content" style="background: transparent; border: 0px; margin: 0px; max-width: 615px; padding: 0px;"><yt-formatted-string class="content style-scope ytd-video-secondary-info-renderer" force-default-style="" split-lines="" style="color: var(--yt-spec-text-primary); white-space: pre-wrap; word-break: break-word;">Il titolo del libro non lascia spazio a molte interpretazioni: il soggetto principale della narrazione è il rapporto fra l'uomo e l'ambiente marino. Di come questo rapporto si sia evoluto nei secoli, dagli approcci dei primitivi con il "grande Blu" fino ad arrivare ai giorni nostri, quando gli uomini hanno reso possibile scorgere in mare ben altri colori, come quelli delle bellissime vele e delle pale eoliche ma anche delle plastiche o delle grandi navi mercantili, pescherecci, petroliere e così via. Come l'attività intensa della pesca e anche dell'allevamento ittico possono, se non ben organizzati, trasformare a lungo termine il "Grande Blu", in qualcosa che somiglia più ad una Grande Palude salata.
Ma badate nel libro c'è anche molto di più: nel percorrere questo lungo viaggio narrativo, gli autori hanno scoperto, per esempio, cosa hanno a che fare con la pesca le scollature femminili, come mai gli antichi cristiani usavano un pesce come simbolo, qual è l'effetto delle balene sul clima terrestre e persino chi è il nonno di Capitan Findus !

Of all these gases, only CO2 and methane are greenhouse gases (GHG): it seems impossible that such a small fraction of gases are crucial to triggering a major climate change, but that's true. In some old encyclopedia or book, even if only from the 70s and 80s, you will find that the composition of the atmosphere report an average value of GHG gases around 0.025%. It should be noted that an appropriate amount of CO2 was necessary for achieving a temperature on the planet mild enough to allow basic forms of life: indeed, the CO2 molecules have the characteristic of absorbing energy by infrared radiation re-emitted from the soil that is then dissipated in rotational and oscillatory motions of CO2, which cause by friction/collisions the heating of the molecules of all the surrounding gases, including the no GHG ones. So more are the CO2 molecules in the atmosphere, higher is the atmospheric warming potential.<div><br /><b>The carbon cycle explained with a bathtub</b><br />The content of CO2 in the atmosphere is regulated by the carbon cycle. The carbon on our planet is mainly stored in 4 large reserves: as CO2 gas in the atmosphere, in organic molecules - in animals and vegetable - on land and in the sea, as carbonates and fossil fuels in the Earth's crust and dissolved as bicarbonate in marine and fresh waters.To fully understand how this cycle works, let's imagine that the atmosphere is a large bathtub containing CO2 instead of water: the level in the tank is adjusted via an inlet tap and the opening of a drain. It is intuitive that if the inlet flow is greater than the draining one, the level rises, or, viceversa, falls in the reverse situation; if the two flows are similar, the level remains approximately the same.<br /><br />Before the use of fossil fuels, the amount of CO2 that rose into the atmosphere derived mainly from the combustion of wood, fires, the eruption of volcanoes and certainly from the respiration of living beings: we inhale oxygen and exhale CO2. Thanks to chlorophyll photosynthesis, CO2 was, and still is, removed from the atmosphere to create the nourishment of terrestrial and marine plants, which in turn feed herbivores and carnivores. When plants and animals die, the carbon returns to the Earth's crust. Other phenomena subtract CO2 from the atmosphere, for example the carbon dissolved in the water can be fixed by the rocks in the form of carbonates and recall the passage of CO2 from the atmosphere to the water, but it is a much slower process.<br />Until the use of fossil fuels began, the in and out fluxes of CO2 to and from the atmosphere were self-regulate by the previous phenomena and the level of CO2 in the "atmospheric tank" was quite stable and neutral with regard to global warming.<br /><br /><b>What is climate neutrality?</b><br />With the combustion of fossil resources, such as coal and oil (real concentrates of carbon-containing molecules), the flow of CO2 in our atmospheric tank has increased dramatically in a few decades, while the discharge of our tank, based mainly on the draining effect of the photosynthesis, continues to have the same rate of disposal. Therefore, the level of CO2 in the atmosphere has risen and will continue to rise even if we will gradually try to reduce the use of fossil fuels, because, by doing so, we will be reducing the speed with which we feed the tank, but we will certainly not empty it. In fact, even if right now, we suddenly no longer use fossil fuels, it would be some time before the drain of our tank brings the CO2 back to a level that re-establishes a neutral carbon cycle for global warming; in the meantime, however, the climate has changed.<br /><br /><b>What the Green Deal provides</b><br />And this is where the fundamental core of the Green Deal lies: the need to cut out fossil fuels, cut their flow as soon as possible, to slow the inexorable rise in the level of greenhouse gases in our atmosphere and avoid finding the Earth again, in the 2050, overheated far beyond its current level.</div><div><br /></div><div><br /></div><div>By a columun of Ilaria in the italian Magazine <a href="http://www.saperescienza.it/rubriche/geologia/cos-e-il-green-deal-capire-la-neutralita-climatica-con-l-ausilio-della-vasca-da-bagno/2729-cos-e-il-green-deal-capire-la-neutralita-climatica-con-l-ausilio-della-vasca-da-bagno" target="_blank">Sapere Scienza</a> </div>Ilaria Perissihttp://www.blogger.com/profile/01813626341487097669noreply@blogger.com0tag:blogger.com,1999:blog-300324375078004462.post-91728306062511467992020-12-23T19:02:00.002+01:002020-12-30T18:40:26.735+01:00The Empty Sea. The future of the Blue Economy - the new book by Ugo Bardi and Ilaria Perissi<div style="text-align: justify;">The “Blue Economy” is used to describe all of the economic activities related to the sea, with a special emphasis on sustainability. Traditional activities such as fisheries, but also undersea mining, tourism, and scientific research are included, as well as the phenomenal growth of aquaculture during the past decade. All of these activities, and the irresistible prospect of another new frontier, has led to enthusiastic and, most likely, overenthusiastic assessments of the possibilities to exploit the sea to feed the world, provide low-cost energy, become a new source of minerals, and other future miracles. This book makes sense of these trends and of the future of the blue economy by following our remote ancestors who gradually discovered the sea and its resources, describing the so-called fisherman’s curse – or why fishermen have always been poor, explaining why humans tend to destroy the resources on which we depend, and assessing the realistic expectations for extracting resources from the sea. Although the sea is not so badly overexploited as the land, our demands on ecosystem services are already above the oceans’ sustainability limits. Some new ideas, including “fishing down” for untapped resources such as plankton, could lead to the collapse of the entire marine ecosystem.</div><div style="text-align: justify;"><br /></div><div style="text-align: justify;">How Neanderthals crossed the sea in canoes, how it was possible for five men on a small boat to kill a giant whale, what kind of oil the virgins of the Gospel put into their lamps, how a professor of mathematics, Vito Volterra, discovered the “equations of fishing,” why it has become so easy to be stung by a jellyfish while swimming in the sea, and how to play “Moby Dick,” a simple board game that simulates the overexploitation of natural resources are just some of the questions that you will be able to answer after reading this engaging and insightful book about the rapidly expanding relationship between humanity and the sea.</div><p style="background-color: white; border: 0px; color: #333333; font-family: "Helvetica Neue", Arial, Helvetica, sans-serif; font-size: 13px; font-stretch: inherit; font-variant-east-asian: inherit; font-variant-numeric: inherit; line-height: inherit; margin: 0px 0px 0.5em; padding: 0px; vertical-align: baseline;"></p><p style="clear: both; text-align: center;"><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjSazlXmI964GwrCvXLukH6-U0uVmEa1sQdB1noD0yFutyQwDjEL23axYp-J-oHs_oEYDi7U8dftc5ETauoY5LA_MRoTfmJwLnSf1Id7gjxoVoBbU-Yyr2GSX9e27wW022-CDDQU8Ifi8_x/s467/empty+sea.jpg" style="margin-left: 1em; margin-right: 1em;"><img border="0" data-original-height="467" data-original-width="310" height="400" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjSazlXmI964GwrCvXLukH6-U0uVmEa1sQdB1noD0yFutyQwDjEL23axYp-J-oHs_oEYDi7U8dftc5ETauoY5LA_MRoTfmJwLnSf1Id7gjxoVoBbU-Yyr2GSX9e27wW022-CDDQU8Ifi8_x/w265-h400/empty+sea.jpg" width="265" /></a></p><p></p><p style="background-color: white; border: 0px; color: #333333; font-family: "Helvetica Neue", Arial, Helvetica, sans-serif; font-size: 13px; font-stretch: inherit; font-variant-east-asian: inherit; font-variant-numeric: inherit; line-height: inherit; margin: 0px 0px 0.5em; padding: 0px; vertical-align: baseline;"><span style="background-color: transparent;">more at: <a href="https://www.springer.com/gp/book/9783030518974#" target="_blank">Spinger Nature</a></span></p><br />Ilaria Perissihttp://www.blogger.com/profile/01813626341487097669noreply@blogger.com0tag:blogger.com,1999:blog-300324375078004462.post-8329419832773313802019-10-23T09:47:00.002+02:002021-04-20T16:20:15.418+02:00First monograph out !!! <div>

ABSTRACT:<br />
In recent months, we are witnessing a global demonstration of people, predominantly young, spreading a clear message: “we must do something against climate change and do it immediately, the way we live is no longer sustainable”. Despite the urgency of the actions most of the people are not expert in sustainability, thus it is not always trivial to identify the effectiveness of any action, promoted by the collective or individuals, in changing our lifestyle. In the present work, a set of simple system dynamics models <gwmw class="ginger-module-highlighter-mistake-type-3" id="gwmw-15718174764853501871152">are proposed</gwmw> with the aim of helping help the understanding and the teaching of Sustainability and sustainable dynamics to young people and non-specialist. In particular, the study, inspired by the “World Dynamics” work of Jay Forrester, will focus on modelling the dynamics of energy transition from fossil fuels to <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15718174764892315734411">renewables</gwmw> energy, which is <gwmw class="ginger-module-highlighter-mistake-type-1" id="gwmw-15718174764895040138235">recognised</gwmw> as a priority in fighting climate change and in granting the future society with a clean and long-lasting energy supply.<br />

<span style="font-family: Arial, Helvetica, sans-serif;"><div style="text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif;">The purpose of this work I conducted in the frame of the <a href="http://www.medeas.eu/">Project MEDEAS H2020</a> (also <a href="https://twitter.com/projectmedeas">@ProjectMEDEAS</a>, <a href="https://www.facebook.com/ProjectMedeas/">MEDEAS on Facebook</a>) in collaboration with the Global Sustainability Institute of the Anglia Ruskin University (Cambridge, UK) and Consejo Superior the Investigation Cientifica (Barcelona, SP)</span> is to highlight the discrepancy that currently exists between the package of measures to mitigate the climate change promoted by COP21 and those actually adopted by the European Union in the Roadmap 2050 package. </div>
</span><div>
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div>
<div style="text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif;">The COP 21 goal concerns the staying within 2°C of warming by 2100. This target temperature depends on the carbon dioxide concentration that will be present in the atmosphere in 2100, from which originated the idea of “carbon budget”, namely the amount of carbon dioxide gasses we can still emit, from present to 2100, to not overtake that limit. EU measures, instead, only pledge to cut the value of 1990 greenhouse gases emissions flow rates of -80% by 2050, but without giving an estimation or a maximum ceiling of the amount of carbon dioxide will be present in the atmosphere by 2050 (and later on to 2100) thanks to those measures. This is why the impact of the ongoing EU regulations on global warming is still unestimated. </span></div>
<div style="text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif;"><br /></span></div>
<div style="text-align: justify;">
<span style="font-family: Arial, Helvetica, sans-serif;">The aim and the novelty of this study are to propose, for the first time, a carbon budget estimation for the European Union, which represents the most significant physical characteristic to assess the feasibility of current EU-28 greenhouse gas reduction objectives under the goal of 2°C of global warming promoted by 2015 Paris treaty.</span></div>

<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="text-align: justify;"><br /></span></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="text-align: justify;">Last August, I had the opportunity to write a column for the magazine </span><a href="http://www.saperescienza.it/" style="text-align: justify;">"Sapere"</a><span style="text-align: justify;"> (Edizioni Dedalo) in the section "CERVELLI NON IN FUGA" ( translatable in "Brains.... not in </span>drain<span style="text-align: justify;">..."). <b>"Sapere" </b>is the oldest Italian magazine pledged to disseminate Science at a general public; further information on the magazine aims and topics are reported in the footnotes. </span></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"> </span><br />
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Thus, here is the translation of the piece, which starts with the following sentences: </span></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"> </span></div>
<div>
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"></span><br />
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><i><b>"Give a man a fish and he will eat for a day, teach him how to fish and he will empty the ocean. "</b></i></span></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"> </span><br />
<div style="text-align: justify;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span></div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"> <div style="text-align: justify;">
This said may sound familiar, but the conclusion, in fact, was something like: </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
"teach him to fish and eat for all life" </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
You will ask why I transformed this wise statement, which invites the individual to be lively and far-sighted, in a sentence used to qualify a man who, instead, is anything but wise, that grabs beyond what is necessary for the subsistence, leaving behind an empty ocean. The answer is that the new version of the statement describes perfectly the phenomenon of overfishing (<i>fishing over the limit</i>), a term that qualifies modern fishing as a process no longer sustainable for the fish species and for the fisheries’ economy; to understand why we just need doing a small investigation. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
The first case of well-documented overfishing dates back to the nineteenth century when sperm and right whaling in the United States collapsed within a few years after almost one century of activity. The sperm whale is a precious whale, which provided the society with many primary goods, like the oil for illumination, stored in the front part of the whale’s skull; in addition, meat and even the bones were transformed into various types of tools.<br />
<br />
At the end of the 50s, it has been the round of Californian sardines: they were so perfect in cans that at the end few remained in the sea. I also mention the case of the Peruvian anchovy (the 80s), of Canadian cod (1992) and the recent decline of the entire Japanese fishing industry: even after a long time, the values of landing in these areas never returned as abundant as before.<br />
<br />
What's common in these episodes? </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
Thanks to the work done during my post-doc at the Department of Chemistry of the University of Florence, when I began to develop mathematical models inherent to the dynamics of environmental sustainability, I could see that the landing trend, comparing the various historical data, had, in all the aforementioned cases, designed a bell shape curve. This trend is similar to the one described by a famous model of ecosystem dynamics, the <i>prey-predator </i>model. This model describes the dynamics of two populations, of which one is nourishment of the other: when there is an abundance of prey, predators increase, they catch the prey and then starving when the prey is too scarce, a condition that let the prey to reproduce and to return in abundance, closing the cycle. </div>
<div style="text-align: justify;">
<br /></div>
<div style="text-align: justify;">
The problem today is that when the fish goes into deficit, the fishing industry activity, instead of slowing down, becomes more intense to satisfy the unvaried market requests, extracting the fish at a greater speed of that it is able to reproduce, creating a condition of <i>over-exploitation</i>. This causes damage unrecoverable, as in the case of the right whale, now in endangered, or recoverable only partially and with very long time. </div>
<div style="text-align: justify;">
<br />
We need, therefore, to learn from the prey-predator dynamic to respect the rhythms of reproduction of species, avoiding in this way that the environment and the activity of the fishing sector being damaged irretrievably.<br />

The new Sapere magazine focuses its attention on scientific topicality and the history of ideas, giving rise to questions in readers useful to develop the critical sense, without ever forgetting the inseparable link between science and its discoveries on the one hand, and society and its members on the other</i></span><span style="background-color: white; color: #212121; font-family: "arial" , "helvetica" , sans-serif; font-size: x-small; text-align: justify; white-space: pre-wrap;">.</span>Ilaria Perissihttp://www.blogger.com/profile/01813626341487097669noreply@blogger.com0tag:blogger.com,1999:blog-300324375078004462.post-32721144038133638762018-01-01T11:04:00.001+01:002020-12-30T18:19:35.996+01:00Vincent Van Gogh, the modeller<div class="separator" style="clear: both; text-align: center;">

<span face=""arial" , "helvetica" , sans-serif"><span face=""arial" , "helvetica" , sans-serif"><br /></span></span><span face=""arial" , "helvetica" , sans-serif"><br /></span> <span face=""arial" , "helvetica" , sans-serif"><br /></span><span face=""arial" , "helvetica" , sans-serif">Van Gogh was a genius, he invented a really new way of painting, and as you probably know, he has been an almost self-taught artist, and, as I'm going to show you, he has been also a very smart modeller. But, h</span><span face=""arial" , "helvetica" , sans-serif">ow I can affirm that 'to model' is relevant to Vincent Van Gogh operas?</span><br />
<span face=""arial" , "helvetica" , sans-serif"><br /></span> <span face=""arial" , "helvetica" , sans-serif">Let me step back, before to go to the question point, and make me stress you a bit on the concept of modelling commonly intended in scientific areas. In fact, m</span><span face=""arial" , "helvetica" , sans-serif">odelling has been and is an essential and inseparable part of many scientific disciplines evidencing</span><span face=""arial" , "helvetica" , sans-serif"> the high frequency with which our mind struggles to scheme </span><span face=""arial" , "helvetica" , sans-serif">a complex reality </span><span face=""arial" , "helvetica" , sans-serif">to understand it better. J</span><span face=""arial" , "helvetica" , sans-serif">ust think about the importance of the use of 'modelling', for instance, </span><span face=""arial" , "helvetica" , sans-serif">in chemistry, where atoms and molecules are represented with graphical models by which we can solve the structure of almost all the known substance. Or, let's think to mathematical modelling, </span><span face=""arial" , "helvetica" , sans-serif">which is the most ancient and efficient tool to universally capture</span><span face=""arial" , "helvetica" , sans-serif"> the patterns for the <i>changes </i>we observe around us<i>.</i> Moreover, </span><span face=""arial" , "helvetica" , sans-serif">thanks to the birth of</span><span face=""arial" , "helvetica" , sans-serif"> <b>computational science, </b>we passed, in few decades, to scheme a model using pencils, papers and solving equations with hours of manual calculations, to realize it using a computer, with which we can sketch the same equations, now solved, very fast, by an appropriate software.</span><br />
<span face=""arial" , "helvetica" , sans-serif">I used the word ‘sketch’ because, with some of these programs (i.e. google for the terms ‘Vensim’, ‘Stella’, and you will see), even math operators and variables can be represented by graphical objects. It is worth to highlight that those graphical objects often recall the shape of subjects that already have a meaning in our mind (</span><a href="http://systems-sciences.uni-graz.at/etextbook/sw2/vensim.html" style="font-family: arial, helvetica, sans-serif;">arrows = flows, valves = regulators, boxes =stocks</a><span face=""arial" , "helvetica" , sans-serif">) so that, this new language permits 'to write mathematically' in a more intuitive way, allowing a huge saving of time in understanding if a model is catching the system under investigation or not, </span><span face=""arial" , "helvetica" , sans-serif">especially for those are not expert of math stuff.</span><br />
<span face=""arial" , "helvetica" , sans-serif">The development of this kind of 'drawn-mathematical modelling' is mainly due to an idea of <a href="https://en.wikipedia.org/wiki/Jay_Wright_Forrester">Jay Forrester</a>, by which he revolutionised, during the 60s, </span><span face=""arial" , "helvetica" , sans-serif">the study of the 'dynamic of complex systems'</span><span face=""arial" , "helvetica" , sans-serif">, better known as </span><span face=""arial" , "helvetica" , sans-serif"><a href="https://www.systemdynamics.org/what-is-sd" target="_blank">Systems Dynamic</a>. </span><span face=""arial" , "helvetica" , sans-serif">You can find all the information about Jay Forrester, his brilliant mind and his revolution </span><span face=""arial" , "helvetica" , sans-serif">searching in the web, </span><span face=""arial" , "helvetica" , sans-serif">anyway let's keep its name in mind, I will recall him again below.</span><br />
<span face=""arial" , "helvetica" , sans-serif"><br />In the view of the above, we can now reasonably affirm that <b>modelling is an attitude of a rational mind, </b>characterized by th</span><span face=""arial" , "helvetica" , sans-serif">e use of reason or logic in thinking out a problem. A</span><span face=""arial" , "helvetica" , sans-serif">n attitude, getting now to the point, that also the famous artist </span><b style="font-family: arial, helvetica, sans-serif;">Vincent Van Gogh</b><span face=""arial" , "helvetica" , sans-serif"> surely had, as I discovered visiting the Van Gogh Museum in Amsterdam, precisely during an 'off work' moment of the System Dynamic School, I was attended in Delft in summer 2016.</span><br />
<span face=""arial" , "helvetica" , sans-serif"><br /></span> <span face=""arial" , "helvetica" , sans-serif">Van Gogh is famous for having lived an agitated existence, alternating moments of happiness and equilibrium to other blue and irascible moments. Fortunately, he left us proofs about his feelings and his life thanks to a lot of letters he wrote to his brother, Theo. By means these manuscripts we can know him better, anyway in the common imaginations, Van Gogh still remains <b>an icon of one of the most irrational artists</b> in the history of painting. And he seems to think so of himself too:</span><br />
<blockquote class="tr_bq">
<span face=""arial" , "helvetica" , sans-serif"><b>I put my heart and my soul into my work, and have lost my mind in the process </b>(</span><span face=""arial" , "helvetica" , sans-serif">Vincent Van Gogh)</span></blockquote>
<span face=""arial" , "helvetica" , sans-serif">Anyway, if you go in depth in the history of his life and his art, you will find that the previous affirmation describes a feeling that is the result of all, except that an irrational process. And I realised this when I found in the Vang Gogh Museum, his famous ‘box of yarn’, a small Chinese, red lacquer wooden box, that held 16 balls of wool. <br /><br />I knew some episodes of Van Gogh life from the night classes of the Art school <a href="http://www.liceoartisticoalberti.it/index.php/corso-serale">'L.B. Alberti'</a> (website only in Italian) I attended between 2002 to 2004 in Florence, but I didn’t know the existence of this box before to go to the Museum. But when I saw it, I immediately realised he used this box ‘to model’ the colours’ contrast and combinations for his paintings. <br /><br />A tool to paint...Vincent has been..in certain sense, a modeller! <br /><br />Probably I went too fast to this conclusion, as sometimes intuition make you do, but, could I be confident with this affirmation?<br /><br />This fact induced me to investigate more the importance that box could have had in Van Gogh art. Was that box, that modelling tool, really useful for him in understanding a system? <br /><br />The available information about Van Gogh life report he studied the colour theory of <a href="http://www.bc.edu/bc_org/avp/cas/fnart/fa257/blanc_color.html">Charles Blanc </a>in 1884, when he lived in Neunen, dispelling the myth that his talent came out of some automatic unconscious well of genius and/or madness. <br /><br />Van Gogh is also very famous because of the huge production of paintings in a relatively short time: first paintings are dated in 1881 and the latest in 1890, before he died on 29th July of the same year. Take a look at the following graph, which reports the number of Vincent’s paintings as a ‘function’ of time (figure 1):</span><br />

<span face=""arial" , "helvetica" , sans-serif"> <span style="font-size: x-small;">Figure 1. Van Gogh numbers of paintings as a function of time. The first peak corresponds to the period in which the painter approached the colour theory, and used models of others. The second peak corresponds to the period in which he used the own modelling tool, the box of yarn, and his canvases started to look like textile.Data from <a href="https://en.wikipedia.org/wiki/List_of_works_by_Vincent_van_Gogh">Wikipedia</a>, graph by Ilaria. </span><br /><br />During those 9 years, he realised around 1000 canvases, culminating in two production ‘peaks’ in 1885 and in 1888. Could it be reasonable to suppose these higher 'production rates' were related to the use of modelling that helped the artist to catch the 'systems' he wanted to represent? Let's see what the facts tell us.<br /><br />The first peak is in the year 1885, shortly after that Vincent approached the theory of colour using the models of others. Van Gogh quite certainly resorted also the ‘<a href="https://www.sciencesource.com/archive/Chevreul-s-Chromatic-Circle-SS2586157.html">colour wheel</a>’ devised by the chemist Michel Eugène Chevreul, with which he could preview the effect of mix determines tonalities. Probably, this modelling tool gave him a more in-depth understanding of how he could translate what he had in mind on the canvass, culminating in a production of around 150 paintings in the year 1885. We can also note, that from his first paintings of the period 1881-1883, he changed the style, introducing more colours and more contrasts (see the previous <a href="https://en.wikipedia.org/wiki/List_of_works_by_Vincent_van_Gogh">wikipedia</a> source and scroll down the images of the paintings).<br /><br />The second peak in 1888, could be connected with the use of the tool, ‘box of yarn’ (figure 2): Vincent invented is own modelling tool to model the colour combinations, inspired by the work of the weavers he painted in Neunen few years before.<br />It is Van Gogh’s friend, Bernard, who reported about the existence of this box, shortly after the painter death, and he said it was in Paris he saw the box for the first time, from 1886 to 1888 when Bernard met and worked with Van Gogh before Vincent left to Arles. In the paintings of these years it</span><span face=""arial" , "helvetica" , sans-serif"> is clearly visibile the Vincent's famous brushstroke reminding the consistency of a textile. Moreover, with the help of the yarns, he was able to test the combination of colours without waste tempera.</span><span face=""arial" , "helvetica" , sans-serif"> </span><br />

<span face=""arial" , "helvetica" , sans-serif"> <br />Thus, we can now reasonably conclude the maximum production of Vincent paintings corresponds at the moment in which he approached the colours’ modelling tools. But again, what system did he want to represent?<br /><br />Analysing the historical changes in Van Gogh, let’s say, ‘styles of painting’, it is in evidence that Vincent mind wanted to go beyond the appearance of the colours, he ran after the colours' potential up to invented an own modelling tool, the ‘box of yarn, to represent the beauty of Nature and of life, let's say very successfully. In a certain sense, the box and the yarns could represent one of the precursors of the <a href="https://en.wikipedia.org/wiki/RGB_color_model">RGB</a> colour model now implemented in the representation and display of images in electronic systems, such as televisions and computers. <br /><br />Van Gogh approach in modelling is not so far from the one from Forrester. Let’s take a look at the following words from Jay Forrester, with which he defines what is a model:</span><br />
<blockquote class="tr_bq">
<span face=""arial" , "helvetica" , sans-serif"><b>The image of the world around us, which we carry in our head, is just a model. Nobody in his head imagines all the world, government or country. He has only selected concepts, and relationships between them, and uses those to represent the real system </b>(</span><span face=""arial" , "helvetica" , sans-serif">Jay Forrester,1971).</span></blockquote>
<div>
<span face=""arial" , "helvetica" , sans-serif">Could these sentences represent also a painting process? Is a painter a sort of modeller? Following the rational of previous words, most of the painters are interested in reporting an image of the world and the paintings are just models of that images, including both the material world as well as the rapresentation of feelings and situations; they are not models of the whole world, but of a set of selected concepts and relationships used to represent a real material system, which could be a landscape, a still life, a portrait, a situation or event, as wars, battles, a sunset or a ‘starry night’, ‘potatoes eaters’ and representation of feelings as in the painting 'Sorrowing Old Man' or 'Two lovers'.<br /><br />Then we could conclude saying that this is not only the case of Vincent …all what a painter paints can be seen as a model of a real system (material or intangible) and Van Gogh has had the added merit to invent a new modelling tool to do it. <br /><br />So…is this concept reversible and is a scientist, an economist, and any other of the more 'common' intended modellers.. a sort of painters when modelling an image of the real world?<br /><br />No easy to answer, I just can say I like to think so... <br /><br />I wish a good work to all my friends and to have a new year full of inspirations</span>!</div>

<span style="font-family: "arial" , "helvetica" , sans-serif; font-size: small; font-weight: normal;">During the <a href="http://medeas.eu/news/chronicle-medeas-workshop-club-rome-summer-academy-florence-september-9-2017" target="_blank">MEDEAS workshop at Summer Academy of the Club Of Rome</a>, held in Florence last September, I met several amazing students. I looked at them with a bit of envy: I really feel like a student, even today I'm 45 yo. I'm only more aware I have less time to chase the countless things I have left to know.</span></div>
<div>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span> <span style="font-family: "arial" , "helvetica" , sans-serif;">Anyway, while I was speaking with them, some looked very conscious about what they wanted from the Summer School experience and they told me about their nice projects for the future. So glad to feel such an enthusiasm! </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;">Others, instead, looked more wondering about the role of the School in their life and in their futures, they looked to have more questions than answers, they were looking for something and one said to have the sensation of wasting time. These words invite me to tell a short personal story...</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="color: #222222;"><br /></span></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="color: #222222;">In the far 1994, I was already attending the University classes in Chemistry but the study went slowly, several thoughts crowded my mind: what did I really want my future is? Did I do the right choice with that chemical stuff? </span></span><span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span><span style="font-family: "arial" , "helvetica" , sans-serif;">Therefore, I decided to take a look at the labour market and, at that moment, a competition notice as an engine driver was published. The access requirement was to hold a technical high school degree that precisely I have. I won 'the job' and in October 1995 I was employed with a training contract in the Italian Railways company, Ferrovie dello Stato SpA.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">The experience showed up incredible, at least for me: in 2 years of a full-time salaried training and provided that I passed 3 enabling exams (theoretical and practical), I would have been a licensed engine driver, gaining also a permanent contract. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;">I met very nice colleagues, we had classes with instructors(see pictures 2 and 3, not very esthetic, but with privacy) alternate to practical training, driving a real train with real people on board, under the supervision of more expert colleagues. And the job was also well paid, let's say, fortunately, because it is really a challenging job... and so exciting! </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">My preferred engine was the <a href="https://it.wikipedia.org/wiki/Locomotiva_FS_E.656" style="color: #4d469c; text-decoration-line: none;" target="_blank">Caimano</a>, so versatile and powerful, you can see a picture of me (figure 1) in driving it on the railway between Florence and Rome.</span><br />

<span style="font-family: "arial" , "helvetica" , sans-serif;">I felt relieved, I achieved also a good economic independence, a milestone of my life.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;">But after the first year, I realised I didn't want to do this job for the life. Hufs! Crisis again....but it has been not so bad as the first one because I realised I really wanted to go back to study Chemistry, I realised how that world, the world of Science and Research, was and still is really fascinating for me.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;">But...Could I leave that job to renounce at my economic independence? I couldn't...so that I went on with both, working and studying chemistry.</span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Today I'm no more an engine driver, the things changed further short after my contract became permanent at the end of 1997. I found another full-time job to sustain myself and to pay my fees and in 2001 I obtained my Master's Degree in Chemistry...but this is another story. </span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><br /></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Today I earn quite less than an engine driver but, fortunately, the opportunity to manage scientific stuff, in particular, 'to Research' is still in my life. I have never given up and I would like to thank all the people that trusted me and encouraged me in to do it: now I'm enjoying all this as never before and I will do it <span style="color: #212121; white-space: pre-wrap;">while it lasts.</span></span><br />
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span style="color: #212121; white-space: pre-wrap;"><br /></span></span>
<span style="font-family: "arial" , "helvetica" , sans-serif;">Thus...Students, of any kind and age, make up your mind to follow your instinct and passions, even they look confused. Any road you decide to walk, leading far from what you planned or closer to it, will clarify what really you are and you want, and this will be never a waste of time!</span></div>

The project aims at modeling the global and European economy as a function of the availability of natural resources, climate change and the policy choices that have been made and will be made in the future. It is focalized in particular on the effort needed to keep Europe on track of the decarbonization process necessary to attain the objectives of the Paris agreement. The project makes use of advanced modeling techniques, mainly based on system dynamics and it aims at producing a flexible tool designed to help policymakers taking appropriate decisions. The project is ongoing, but the available results already indicate that for the European economy, remaining within the boundaries agreed in Paris, a major effort will be required in terms of improved efficiency, growth of renewable energy and emission abatement.</div>

<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<span lang="EN-US" style="color: #222222; font-family: "arial" , "helvetica" , sans-serif;">In the <a href="http://www.medeas.ue/" target="_blank">MEDEAS</a> project ( the acronym states for </span><span lang="EN-US" style="color: #212121; font-family: "arial" , "helvetica" , sans-serif;">Modelling Energy system Development under Environmental And Socioeconomic constraints) more than 10 partners from UE countries, work on how to shift the energy provisioning necessary to drive all the activities of the modern society from fossil fuels to renewable energy.</span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<br /></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<span lang="EN-US" style="color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">The reason for the existence of such project states mainly in 2 points:</span></span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<br /></div>
<div class="MsoListParagraphCxSpFirst" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm; margin-left: 38.5pt; margin-right: 0cm; margin-top: 0cm; mso-add-space: auto; mso-list: l0 level1 lfo1; text-indent: -18.0pt;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span lang="EN-US" style="color: #212121;">1.<span style="font-stretch: normal; font-variant-numeric: normal; line-height: normal;"> </span></span><span lang="EN-US" style="color: #212121;">The first is the concept that fossil fuels are treasure buried under the surface of finite dimension planet, and this is why sooner or later they are going to finish, independently from the effort we put in discover them. </span></span></div>
<div class="MsoListParagraphCxSpLast" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm; margin-left: 38.5pt; margin-right: 0cm; margin-top: 0cm; mso-add-space: auto;">
<br /></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<span lang="EN-US" style="color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">This is what we call ‘a physical limit’: this kind of reservoirs can not be infinite because the planet is finite. Moreover, the fossil fuel resources are not renewable, because oils and gas are the products of complex and long time-taking geological transformation happen under the crust, in extreme environmental condition of pressure and under several biological material degradation processes. Those conditions are not easy to reproduce even in a lab. Thus, this point fixes that we should image a future society based not on this kind of resources.</span></span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm; margin-left: 20.5pt; margin-right: 0cm; margin-top: 0cm;">
<br /></div>
<div class="MsoListParagraph" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm; margin-left: 38.5pt; margin-right: 0cm; margin-top: 0cm; mso-add-space: auto; mso-list: l0 level1 lfo1; text-indent: -18.0pt;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span lang="EN-US" style="color: #212121;">2.<span style="font-stretch: normal; font-variant-numeric: normal; line-height: normal;"> </span></span><span lang="EN-US" style="color: #212121;">The second, and maybe the most urgent to deal with, is that the use of fossil fuel is 'one' of the main responsible of the GHG emissions: several studies assess if the GHG concentration would rise to 25% of the present concentration, an irreversible over-heating of the planet occurs. </span></span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<br /></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<span lang="EN-US" style="color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">The GHG emissions are not only from fossil fuel combustion, this is why the argument is very debated, but it is undoubtedly true the largest contribution comes from the activities of the post-industrial era.</span></span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<span lang="EN-US" style="color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">Image a new society based on RE, or rather, trying to make the transition toward a cleaner and renewable energy sources looks like the right solution for both the problems reported at point 1 and point 2. </span></span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<span lang="EN-US" style="color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">How to get there? How can we move toward the transition? </span></span></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<br /></div>
<div class="MsoNormal" style="line-height: normal; margin-bottom: .0001pt; margin-bottom: 0cm;">
<span style="font-family: "arial" , "helvetica" , sans-serif;"><span lang="EN-US" style="color: #212121;">According to</span><span lang="EN-US" style="color: #212121;"> the preliminary results obtained in the MEDEAS project, performing simulations with models and analysing several historical data, the transition will be possible and sustainable, only if we put our effort on building RE energy infrastructures, lets’ say... urgently!</span></span></div>

<span lang="EN-US" style="color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">The picture tracks an evolution path of the information propagation during the past years, it compares the speed necessary to an information to carry out a complete trip around the world. Reversely it also shows the physic distance is virtually shortened as consequence to the increased information (that nowadays is become the <b>informatization</b>) capacity. In another word, Harvey announced the dawn of globalisation.</span></span></div>

<span lang="EN-US" style="color: #212121;"><span style="font-family: "arial" , "helvetica" , sans-serif;">That the capacity to diffuse information depends on the available 'energy', it's not explicitly reported in this picture, but we can sure to prove it simply doing a short research on the kind of energy resources that, in each period, drove the society.</span></span></div>

<span style="font-family: "arial" , "helvetica" , sans-serif;">In this period, a mixture of energy resources is available for the society. The main energy provisioning is in charge to the animals, both for transportation and agriculture, but also renewable energies, as the wind and the water flows were already exploited in manufacturing, in food production and in driving several other human activities. </span></div>

Moreover, with oil, a so light and energy dense resource, the aviation is quickly developed a few years later, pushed by the incoming First world war 'necessities' to fly.</span></span><br />

Refineries became more sophisticated producing new powerful fuels, but the more important new entry is the uranium, now used to produce electric energy and heat in nuclear plants. In 1942 we have the first controlled nuclear reaction (Fission) and in 1954 ex-URSS built the first reactor for civil use. Uranium became a new non renewable fuel resource. </span></span></div>

Medeas construeix una aplicació informàtica que, amb dades de tendències ambientals, energètiques, econòmiques i socials, permet projectar i fer simulacions de la transició a les renovables. Una eina que ha d’ajudar a analitzar, planificar i accelerar la transició energètica.</span></div>

<span style="font-size: x-small;">SCIENTIFIC PUBLICATION "THE SOWER’S WAY: A STRATEGY TO ATTAIN THE ENERGY TRANSITION" BASED ON MEDEAS PROJECT RESULTS</span></h1>
<div>
MEDEAS<span style="background-color: white; color: #373737; font-family: "roboto" , "verdana" , "arial sans-serif"; font-size: 13px;"> partners from INSTM have just published a scientific article in the International Journal of Heat and Technology, entitled </span><em style="color: #373737; font-family: Roboto, Verdana, "Arial sans-serif"; font-size: 13px;">"The Sower’s Way: A Strategy to Attain the Energy Transition"</em><span style="background-color: white; color: #373737; font-family: "roboto" , "verdana" , "arial sans-serif"; font-size: 13px;">.</span></div>

<div style="background-color: white; color: #373737; font-family: Roboto, Verdana, "Arial sans-serif"; font-size: 13px; line-height: 1.6; margin-bottom: 16px; padding: 0px;">
The energy transition from fossil fuels toward renewable energy resources can be seen as a process similar to the challenge faced by ancient farmers who had to save some of their harvests as seed for the next harvest: we need to save and invest part of the energy produced by fossil fuels in order to build their own replacement in the form of renewable energy plants. This strategy is called here <em>"the Sower’s Way"</em>.</div>
<div style="background-color: white; color: #373737; font-family: Roboto, Verdana, "Arial sans-serif"; font-size: 13px; line-height: 1.6; margin-bottom: 16px; padding: 0px;">
The calculations to quantify the allocation of the energy necessary today to attain the transition (represented by the curves in the figure) indicate that a considerable increase in renewable energy installations and plants is necessary and that it is essential to invest, as soon as possible, in their implementation.</div>
