Anecdotes like that with a 1 year horizon.. that's what we call weather.
A 1,200 year time series.. that's definitely in the climate area.
We say the same thing about southern California. When the forecast is the same for 350+ days out of the year, that's not weather, that's climate.
I say that as someone from Texas that lived in LA for several years. Texas weather changes by the hour and this time of year it is advisable to keep an eye on it. In LA, you could go weeks without checking the "weather".
Weather can be due to climate, and time series are composed of anecdotes.
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.
If you go back a few million, that's also climate. We're still in an ice age. https://www.climate.gov/media/16817
