Why London is ahead of the rest of the country in cycling? Yes, the answer is the infrastructure:

Cycling is changing at speed – but is Britain keeping pace?

Emulating the bike-friendly highways enjoyed by our continental neighbours will take a lot more money and political will

The Guardian
Our estimates off DfT data is London's 1.5 million cycled journeys daily now accounts for well over half of all cycle journeys made in England. That's an amazing end-of-year reflection alongside this ace @peterwalker99.bsky.social@bsky.brid.gy piece about what London & LCC included is getting so right...

Peak glacier extinction in the mid-twenty-first century https://www.nature.com/articles/s41558-025-02513-9
Using three global glacier models, this project predicts a sharp rise in the number of glaciers disappearing worldwide, peaking between 2041 and 2055 with up to ~4,000 glaciers vanishing annually. Regional variability reflects differences in average glacier size, local climate, the magnitude of warming and inventory completeness.
Peak glacier extinction in the mid-twenty-first century - Nature Climate Change

Many mountain glaciers will disappear with warming. Here the authors assess how many glaciers will disappear per year under different warming scenarios, finding that a peak in glacier loss will happen during the mid-twenty-first century.

ACCIDENT LYON 18/12 RECHERCHE TEMOINS 📣🚴
Bonjour, ma mère, cycliste de 75 ans a été renversée volontairement (suite à une altercation avec une voiture garée sur la PC) hier après-midi à Lyon Saxe Gambetta, vers le groupe scolaire Chavant. Elle est toujours hospitalisée et doit être opérée aujourd'hui... Nous sommes à la recherche de témoins de la scène, car il y en a eu (des gens lui ont porté secours et ont relevé au moins une partie de la plaque de la voiture). Etant du côté de Marseille, je ne connais pas les groupes lyonnais, je jette donc une bouteille à la mer et compte sur vos partages. Mille mercis par avance.
