Monks in Kyoto kept records of the peak day for cherry blossoms starting in 812 CE -- indirectly giving us over 1200 years of climate data.

It should surprise no one that this decade is having the earliest blossoms in that whole database.

Day of the year with peak cherry tree blossom in Kyoto, Japan

The vertical axis shows the date of peak blossom, expressed as the number of days since 1st January. The timing of the peak cherry blossom is influenced by spring temperatures. Higher temperatures due to climate change have caused the peak blossom to gradually move earlier in the year since the early 20th century.
