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. With so many conflicting headlines out there, it's tough to sort fact from fiction when it comes to climate change and the solutions we need for a cleaner future. The first piece of good news is that data scientist Hannah Ritchie is here with answers, and the steps we need to take now. Using simple, clear data, she tackles questions such as, 'Is it too late?', 'Won't we run out of minerals?' and 'Are we too polarised?'. The second piece of good news: the truth is way more hopeful than you might think. We're at a critical moment for our planet, and getting the facts straight is step one. But even more crucial is feeling hopeful about what we can do next. The third piece of good news? We already have many of the solutions we need to create a more sustainable planet for future generations.
