You can help if you: 🌸 Have botanical expertise and can identify Yamazakura peak bloom from photos 🌸 Are local to Arashiyama and have access to species-specific bloom reporting Please DM me here or email me at tuna@ourworldindata.org. Even a lead helps — thank you!

Prof. Aono tracked a specific species — Yamazakura (Prunus jamasakura) — in a specific place: Arashiyama, Kyoto. We've contacted his university, local organizations, and weather services, but unfortunately none can continue the series. We’re looking for someone who can help us continue it!

I'm a data scientist @OurWorldinData and I need help from a botanist or someone local to Kyoto, Japan! 🌸 We present one of the world’s longest climate records: 1,200 years of peak cherry blossom dates in Kyoto. The researcher who maintained it, Professor Yasuyuki Aono, sadly passed away last year.

🧵 Ever wonder how far most international migrants travel from their home countries? It turns out, not very far at all. For @OurWorldInData, @antea04 and I took a closer look at the data—and the results might change how you see global migration.
