Ever since I became Channel 5 weather presenter in 2010, I've been aware of this growing problem. In that year, we had one of the coldest winters on record - 'Snowmageddon', the tabloids coined it. But this movie-like scenario had no happy Hollywood ending. Thousands of 'excess' deaths were caused by the extreme conditions five years ago, and the death toll has been rising ever since. So, you're probably thinking, how can this be possible in a first world, affluent country? Surely we're all used to the British weather by now?
