We have a cherry blossom tree. It bloomed a week earlier than last year. We’re not in Kyoto but I did notice and it’s a bit strange. I also noticed some other blossoming trees that typically bloom for about a week, went green after 3 days.

Anecdotes like that with a 1 year horizon.. that's what we call weather.
A 1200 year time series.. that's definitely in the climate area.
Much shorter periods can of course also be considered as such. I suppose exactly how short is subject to some debate.

Weather can be due to climate, and time series are composed of anecdotes.

Key words: can be
Longer time series are indeed composed of many samples/anecdotes.
I'd trust such data a lot more, from any other source.

It's about trust anyway.

Longer periods can be called paleoclimate. As you may have noticed, most types of humans did not exist in previous climates, and we are unfamiliar with the conditions of those time periods, much less if we were to bring them upon ourselves in a period of time that isn't even capable of being shown on the chart you've chosen to use.

Climate is also dimensional. Kyoto is a point. A point over time is a line, a line through a 3d set of data. That a single point is seeing an effect is interesting but not as significant as widespread changes. Only when multiple measurements create a 2d map of realtime data, which becomes a 3d bulk over time, should we draw conclusions. Sadly, that is also happening. But the later should be the topic of conversation, not a single very visible data point.
Trees often bloom based on the surrounding climate and conidtions. Warmer bursts in early spring lead to early blossoms.

Many factors in this. Heat islands from urbanization in Kyoto, different species bred for earlier blooming, etc.

Is the "etc" here "because of human greenhouse emissions, the earth is rapidly warming"?

If these events where random noise then they would distribute in both sides of the climate models; We don’t observe that. Events only seem to match or be worse than expectations.

lo heat, why doth thou radiate? from your islands; blooming species differently...

If only we had a plausible hypothesis that covered not only early blossoms in Kyoto, but hundreds of other observations in climate all in the direction of a rise in global temperature, be it in urbanized areas or in remote regions like Antarctica or glaciars... Damn scientist, they might be sleeping or something.

Really disappointing first parse of the comments.
My average comment quality is pretty terrible, but these are on par.

Now this is climate science I can get behind.

I had visited to see the cherry blossoms in 2017 and felt that we were going too early but actually made it for the peak. It’s scary how quickly the dates are shifting.
I wonder what impact the earlier blooms have on the trees over the coming years, as this does not seem to be natural.

A dataset curated by humans, spanning over a thousand years, is awe inspiring on its own. The first person to record their observation must have had no idea what they started. Are there others like this?
