As meteorologists tell us that the chance of snow is decreasing year on year, Sara Wheeler reflects on a future where younger generations may never get to experience snow - and what that means for a season so ingrained in our lives and culture.

'But if climate change blanches the seasons, one wonders what the as yet unborn writers will reach for when they try to put the unsayable into words.'
