About Giorgio Graffino

I'm doing research about climate modelling at the University of Reading (United Kingdom), after getting my Bachelor's Degree in Atmospheric Physics and my Master's Degree in Earth System Physics, in Bologna, and a Ph.D. in Earth System Science, in Trieste . I like science and communication, and I'm collaborating with Minerva since 2021, after being part of the association Sinapsi and joined Pint of Science.

An extreme summer

2022-10-04T17:42:19+02:004 October 2022|Categories: Earth and Sky|Tags: , , |

L’estate appena trascorsa è stata difficile sul fronte degli eventi estremi nel mondo. Partiamo da casa nostra. Dopo mesi di siccità, nella serata del 15 settembre le Marche sono state interessate da un temporale autorigenerante, un tipo di perturbazione molto pericoloso, caratterizzato dalla sua capacità di autoalimentarsi e stazionare sulla stessa zona per ore. Abbiamo già parlato di questo evento in un post [2]. Aggiungiamo solamente alcuni dati che al tempo non avevamo. La perturbazione ha portato a precipitazioni molto intense, beyond 400 mm di pioggia cumulata in alcune zone, secondo la Protezione Civile [1]. In meteorologia, 1 [...]

The Great Green Wall: story of a rebirth

Recent climate change does not have the same impact anywhere in the world. In fact, there are regions that are most affected by its effects., both from a social and economic point of view. In general, we talk about an increase of heat waves, sea level rise and soil aridity, and an increase in diseases transmissible to humans. All of this could get worse in the future and the scenarios are certainly not positive. If we weren't talking about global warming, you could say it doesn't rain but it pours. The worst effects of climate change are in fact seen in developing countries [...]

The strange shape of the Earth

2022-04-22T11:55:17+02:0022 April 2022|Categories: Earth and Sky|Tags: , , , |

What is the shape of Earth? Sounds like an easy question but it's not at all. The dispute over the shape of the Earth has been going on for millennia, perché si tratta di un problema tutt'altro che banale. Despite what the flat-earthers say, l’ipotesi della “Terra sferica” era nota già nell'Antichità: using a very ingenious geometric method, il matematico Eratostene calcolò con sorprendente precisione le dimensioni della Terra [1], wrong a few hundred kilometers only. A trifle, considering the method. Tutto questo in barba a Cristoforo Colombo, who several centuries later blatantly misjudged his estimates, tentò di raggiungere le Indie via mare e fu [...]

Winter Olimpics Games, on the brink of extinction

2022-02-10T18:20:27+01:0010 February 2022|Categories: Earth and Sky|Tags: , , , |

The 2022 Winter Olympic Games are currently ongoing in Beijing. Other than in the China capital city, competitions are also held in the nearby mountainous areas of Yanqing and Zhangjiakou, which are usually too dry to have a good snow cover, needed for running the competitions. The lack of snow is the main concern of the organizers. Artificial snow is one of the potential solutions [1], which is more and more employed all over the world, to make up for the lack of natural snow. That leads to sustainability issues, of course (we'll covered that later), ma [...]

Giorgio Parisi, the essence in the complexity

It's the 5 of October 2021, at the end of incredible year for Italy, for better or for worse. It's not over yet though. That day, in fact, Sweet at the bottom, in Stockholm. Along with climate physicist Hasselmann and Manabe (a first for the field), the Academy gives half of the Nobel Prize 2021 to the Italian physicist Giorgio Parisi [1][2]. The motivation for the assignment is "for the discovery of the interaction between disorder and fluctuations in physical systems from the atomic scale to [...]

The climate has changed

2021-11-02T23:59:20+01:002 November 2021|Categories: Earth and Sky|Tags: , , , , , |

The climate has changed, Time is up. The twenty-sixth edition of the annual Conference of Parties (COP26), literally "Conference of the Parties", starts this week in Glasgow (Scotland), in collaboration between the UK and Italy. The conference is held one year after the originally scheduled date, due to the COVID-19 pandemic, and sets itself ambitious goals. We already talked about the COP a few months ago on the occasion of the US re-entry into the Paris Agreement, but perhaps it is appropriate to refresh the subject. In summary, the COP has been organized every year since 1995 by the United Nations, under the [...]

Welcome back, USA!

The United States is finally part of the Paris climate agreement. Ready, to the posts, via. Just established, la nuova amministrazione a stelle e strisce di Joe Biden ha fatto rientrare gli USA nell'accordo sul clima di Parigi. This is a nice change of pace from Donald Trump's previous administration, who had decided to leave that agreement. For the occasion, climate expert Ed Hawkins has produced a special version of his famous warming stripes. Despite what some people think, the Paris Agreement does not only concern the citizens of the French capital, but all of us. But one question is legitimate: what's this [...]
