At Waterloo Station, hopeful new arrivals from the West Indies step off the boat train, ready to start afresh in 1950s London. There, homesick Moses Aloetta, who has already lived in the city for years, meets Henry 'Sir Galahad' Oliver and shows him the ropes.

Forget everything you think you know about global warming. It's not about carbon - it's about capitalism. The good news is that we can seize this crisis to transform our failed economic system and build something radically better. This is a book that redefines its era.
