The weather seems wrong!

This morning I have given the kitchen floor a good wash. I opened the back door in the hope that it would dry the floor off. Just realised that it has now been open for an hour, heating turned off and I am walking around in a t shirt and not at all cold. All of this in the middle of December. When we were young we were wrapped up like little Eskimos from early November. What is happening? Global warming I suppose. Apart from all the terrible rain in Cumbria etc. I am not complaining but it is odd. (Will probably snow next week)
