“Safe as houses” is a comforting line, but not one to be taken too seriously if your house happens to teeter on the edge of Britain’s crumbling coastline, parts of which are slowly but surely being eaten away by the elements. Can we protect the land? With climate change meaning raised sea levels and an increase in violent storms, the forces are not in our favour (page 8). For a neat way of explaining the forces that allow hundreds of tonnes of metal to get off the ground and stay in the air, grab a hair-dryer and turn to page 6.
