Now as a man i only really remember the very few christmas's that it snowed but in my mind all christmas's were like it. How cold would have to have got -20 for quite a while.
I was just thinking about the tidal comment about the Thames. If it rises with the tide, surely there would be salt water in it. In which case, UKS is spot on, the temperature would have to drop MASSIVELY to freeze it.
I'm not sure if the pictures are true, or if they are an artistic idealisation. Eitherway, it's a cool thing if it did/could happen.
