We can't afford to delay climate action, but with all the shouting and disagreement it's hard to know where to turn. In her new book, bestselling environmental star Hannah Ritchie answers 50 key climate questions once and for all, clearing the air so we can get on and fix things.

Q: Aren't our efforts pointless if China's emissions keep growing? A: Experts believe China's emissions
could peak within the next few years.

Q: Surely we don't have enough land for everyone to go plant-based? A: If this happened we'd actually free up land currently used to produce animal feed.

Q: Isn't nuclear power dangerous? A: Nuclear power is in fact far safer than fossil fuels.

Q: Isn't it already too late? A: Every tenth of a degree matters. There's no point at which it's too late.
