What you said about the weather in Germany is very similar to what happened here. This is not surprising, because the distance between us is not so great. However, our January still has a chance to become the warmest on record.

If time permits, I will follow your suggestion and check your observations by looking at our region.

I'll be interested to read even if the post appears in a month or more :)

BTW: I already saw the first green tips of my newly planted flowers (maybe this is also a small proof?!). I hope the cold weather in the next few days will not harm them.

I also noticed young green shoots. A few years ago, I planted snowdrops in the garden. Those flowers growing by the garage wall have now put out tiny green shoots.

In past winters, I also noticed this, and not only in snowdrops. It seems that the cold does not harm these shoots, or maybe in the spring the plants quickly grow new ones.
