Assez facilement, je confirme… prévoir 400mm diamètre est une précaution 😀

INTERVIEW. "Cette mesure nous met en colère et est complètement inutile", conteste le syndicat Snep-FSU après l'annonce de tests de forme physique au collège Dès la rentrée prochaine, des tests de forme physique seront généralisés à l'échelle nationale chez les collégiens de sixième.

Enfin @radiofrance.fr ! Il n’est pas question « d’évaluer la « qualité physique » des collégiens »… condition, forme sans doute, mais n’en rajoutons pas ! www.francetvinfo.fr/sports/inter...

Parce que la compétition n’est pas un moteur fondamental de la recherche mondiale ? C’est mal lire les 20 dernières années de prix Nobel et autres Fields…

Zavez l’impression que c’est d’aujourd’hui ?? 🤣

Sure ! Which happens as water depth reflecting sky blueness increases as superimposed on yellow sand 😊

C’est à cause de la base 12 = nombre de phalanges dénombrables avec le pouce sur une main. De même, la quinzaine de jours, en fait 14! Nb total de phalanges. Héritage antique gaulois. C’est plutôt sympa comme héritage non ?

Pas des forêts de la planète justement… en Europe, l’otan d’abord. Et on fera sans (de la bonne dépense etc)

Mmm… ça me rappelle une histoire pour enfants, le grand ménage de monsieur blaireau (déjà le titre 😎), qui finit bien mal… pour monsieur blaireau.

10 years of ago, LIF @ignfrance.bsky.social had this idea that investing the monitoring of CC impacts on forests was a major priority. Accordingly - and unfortunately - French forests are now showing a widespread growth decline, as evidenced by Lionel Hertzog www.sciencedirect.com/science/arti...

10 years ago, we had this idea of using tree cores of the French NFI @ignfrance.bsky.social to massively measure wood density in a medical scanner @inrae-france.bsky.social. This is now done for +100000 cores in +150 species. Congrats to Leban & colleagues Inrae/NFI ! www.nature.com/articles/s41...

10 years ago, we had this idea of a theoretically grounding the estimators of the French NFI @ignfrance.bsky.social … This is now done, further with new simulation facilities based on digital twins. Congrats to our PhD student Trinh Duong ! academic.oup.com/jssam/articl...

LIF lab happy to celebrate its 10 year anniversary 🎂 @ignfrance.bsky.social #ENSG today during the IGN research days ! Also 40th anniversary of IGN research, that allowed LIF’s birth. Thanks to all contributing energies over these years !

Fort intéressant ! Mais sans aller aussi loin, j’ai aussi vu des jardins réagir de la même façon face au bonhomme… @pascal-frey.bsky.social #Annevoie #Belgique

Be careful Francis, this looks like a strange sign of celtic magics. Did you also see a white deer passing through ? 😉

Finland's forests have become a source of carbon The latest preliminary data from Finland's 2023 greenhouse gas inventory reveals that forests have shifted from being a carbon sink to a carbon source. The latest inventory indicates that forests beca...

❗Finland’s #forests have become a source of carbon, according to the preliminary inventory data from @luke.fi. The change is attributed to increased logging, rising emissions in #peatland forests and declining #carbon sink of mineral soils.

#FRA2020 Over 1990-2020, the global forest wood stock has remained stationary, moving from 559.7 billion m3 to 556.5 billions. Despite increasing growing stock density in almost all regions of the world, deforestation predominates in influencing the global stock. There is no global forest C sink.

Confronting risks of mirror life Broad discussion is needed to chart a path forward.
