As I said - the issue I have that a year having a different temperature from the average of some timeframe is not actually "anomal". It is to be expected. It would in fact be weird in most cases if temperature would be exactly like the average.
So calling any difference to the average an "anomaly" seems misleading to me.
The trend of rising temperature may still be "anomal", but that is not what they are referring to.
Your explanation kind of points out the problem, as you also seem to think a "deviation from the norm" is somehow unusual.
If you look at another example, it should be obvious: take the average temperature throughout one year, then plot the "anomaly" of daily temperatures in that year against the average temperature of the year. Then in summer it would be "anomaly hot" and in winter it would be "anomaly cold". Except it wouldn't actually be anomal to be hotter in summer and colder in winter at all.
