Most after-the-apocalypse type scenarios would deal with extreme situations, but the rather more believable effects of climate change in a recognisable England are convincingly nasty.

This would have a major resonance for anyone with a feeling for how fragile our society is at a climatic tipping point- isn't that all of us now?
