It's nice data, but I think the article is overselling it. It's an indisputable evidence of climate change at Japan. However, we do know from historical records that a regional climate can change in its own way. (E.g., the Medieval Warm Period and the Little Ice Age of Europe.) The good(??) news, of course, is that we have global coverage of the current climate, plus thousands of regional records going back to prehistory - taken together, they are truly indisputable. Basically, no serious researcher in 2021 is trying to "prove" (or disprove) AGW, any more than trying to prove the theory of germs. It's proven. What's left is details.

(author here) As I said in the article, I was hoping to find more data sets from around the world (five different ones would have been nice), but I really couldn't find anything else comparable to the Japanese cherry blossom records. Yes, of course, we have plenty more evidence of a different variety: paleohistorical records, temperature models, and very comprehensive modern-era measurements. But nothing else "that has been consistently recorded, in writing, more-or-less annually, for the past 1,000+ years". I'm not trying to prove or disprove global warming either, think of my article as just the icing on the cake.
