I remember that when I first started cycling to school, I always took a rainproof riding cape with me in my bag, because you never knew if it was going to be raining by the end of the day. Six years later, in the 6th form, I stopped bothering because by then you knew if it was going to be sunny.
Similarly, I used to expect that snow would lie, in the South of England, for at least a couple of weeks in Winter. Nowadays it's rare.
We're in the first week of December, and have yet to have a ground frost. This time last year there was snow on the ground. This Iris is flowering forlornly in response to the mild conditions, braving the drizzle and wind that are the main features of the weather today.
I don't know what's happening to the climate, but it seems to be getting quite wierd.
