Five years of no flying

✈ ❌ âžĄïž 🚅 ✅

5 years ago, I realised that my #academic travels were emitting way too much #greenhouse #gas #GHG (up to 20 t #CO2 / yr) and hence that my #professional activity was not #sustainable. I thus decided to completely ban air #travel (#plane) and travel mainly by #train within #Europe.

5 years later (i.e. now), my professional travels' #carbonfootprint dropped by **a factor 50**, without impacting my #publication records (compared to 2017 - 2019).

I wrote a post for the #blog of nostr:nprofile1qy2hwumn8ghj7un9d3shjtnddaehgu3wwp6kyqpqje6qfvqd6ptf8m4vphxtc3zhf06gqdurlefpzf2q8v47964ust7sgd0fm0 about my experience. Check it out: https://astronomersforplanet.earth/five-years-of-no-flying/

nostr:npub1h3e5xm8fq775g88wjrvk8xzmw8txdzkrny7j8sg209x96s6l2guqlfeklu oui, c’est sur. Hard Rock meme.

Mais, bon, y a encore espoir que ca ne soit pas du heavy metal đŸ€˜ quand on n’y sera plus.

perso, je suis confiant. ca va faire mal, tres mal mĂȘme, mais quand on aura majoritairement allumĂ© l’instinct de protection, on fera des choses radicales. J’imagine qu’a un moment, ca se passera pas du tout bien pour une partie de la population qui continuera a s’en moquer.

Si _nous_ perdons espoir, tout est fichu. courage!

I agree this is an important piece of work that was lead by Tamara Ben-Ari and Gaëlle Lefort.

This is just the beginning of the exploitation of the GES1point5 database.

Bravo, est-ce que cela s'inscrit dans le cadre de la Semaine EuropĂ©enne du DĂ©veloppement Durable. Je porte pour ma collectivitĂ© un riche programme de sensibilisation fait de Fresques, ateliers , visites et webinair.😉

nostr:npub1eqvn9gju272ry5uwln76gw5ymenqhzufg38yeamlvwz6jq76lw4spsuvuf Non, pas que je sache. Cette journée était en projet depuis quelques temps mais il a fallu un peu de temps pour mettre en place le réseau des référent·e·s DD dans la région.

Excellent le programme de sensibilisation. De quelle collectivitĂ© s’agit-il ?

PremiĂšre journĂ©e des rĂ©fĂ©rent·e·s #DĂ©veloppementDurable organisĂ© par l’#universitĂ© d’#Aix-#Marseille et la dĂ©lĂ©gation rĂ©gionale du #CNRS.

On parlera des actions à prendre au sein des #laboratoires de #recherche pour s’engager dans la #transition #environnementale.

nostr:npub1fd0kkmxjegh2ypw9k2jnjk2x4xhxg6h7xyey8a34mqkqg3ncdk3qvh8cdv TrÚs sympa. Souvent vu depuis le pic, mais je n'y suis jamais allé !

Ça donne envie de retourner en vacances dans les PyrĂ©nĂ©es quand les enfants auront des jambes plus musclĂ©es.

Ça donne quoi comme distance / dĂ©nivelĂ© ?

nostr:npub10awlk6z27z2hrj55xgyw3flej2pfpmmy5md776p2z9ydfxr9z8qqllvaep As always, we need X deaths at once to make politicians to react.

X needs to be very high in that case !

 i.e. cases when aren’t completely disinformed but we aren’t top experts either.

“Agreement”, on the other hand, sounds to me as if it presumed equivalence between both our reasoning processes (the expert’s & mine), and that’s often not the case.

I have tested #BlueSky for the past few weeks, for curiosity.

It's a bit like #X but you need an invitation code to join. A kind a private club.

I don't have many followers / people to follow, so it's a bit dead. Some folks are obviously cross-posting from X so there is some activity there, but quite limited.

#fediverse is still by far the best social network, no doubt !

PS: if anyone wants to test it, I have 1 invitation code (DM me). Requests from pseudo accounts will be ignored.

nostr:npub1clpsnzraw37vx48lkvtc6aeyzpn0yhrzurm4vhm00h9mve8lv8hsmn4ge5 according to my Spanish colleagues, Chilean are not speaking Spanish at all
 it’s Chilean 😉

Even for them, they need to learn how to speak there 😅

This being said, good luck 😁
