Global warming has made White Christmas an image of the past  Global Warming means that few people will ever get to see a white Christmas. Many of the most populated areas of Western Europe and the USA could once expect snow at Christmastime, so perhaps the idea of a white Christmas once had real meaning. Now we have to accept that those days have gone. Mankind's damage to the world's climate means we have to get use to a coldish, greyish Christmas each year. There is no point dreaming, and denial can even be harmful, as we will be disappointed every year. We need to learn to love Christmas for what it is in the modern world.
