🌡️ Rares voire rarissimes en France au XXe siècle, les températures dépassant localement les 40 degrés sont devenues fréquentes depuis l’an 2000. Voici une carte animée localisant chaque année où les stations de Météo-France ont relevé ou dépassé 40 degrés (données au 17 août).

Jane Fonda à la Screen Actors Guild : "Ne vous y trompez pas, l'empathie n'est pas une faiblesse ou un truc woke. Et d'ailleurs, être woke signifie juste que vous en avez quelque chose à foutre des gens autour de vous." Cette dame est le fer de lance de la résistance à Hollywood et l'a toujours été.

How did you come to work in the geospatial industry or use geospatial tools? What drew you here? What was your journey to get here?

After a @Bellingcat workshop years ago, a participant built a geolocation tool to find locations that all had i.e. a library and a cafe in a 20m radius. Now, there's a supercharged version of that tool! Thanks @sanjanamv.bsky.social for flagging it. www.findthatspot.io

I'm doing more & more research on the history of GPS and I'm amazed by the official US Gov's dedicated website for GPS: gps.gov

It's so old school it actually looks cool
And it ends up quite easy to navigate (would have been ironic otherwise)
