this book informed me as an engineer, excited me as an entrepreneur, and inspired me as a mindful human who is aware of his fleeting moment in the cosmos. saul did a wonderful job bringing together leading research and gov data to create a practical guide to decarbonize. in short, he asks for the world to mobilize with wartime-like efforts and invest our time, energy, and funding into renewable technology that have already proven itself (like solar, wind, nuclear, EV). meanwhile, actively cut reliance on oil and gas products in whatever way most appropriate for us personally (teacher, engineer, CEO, entrepreneur...). this book has expanded my interest in climate science and i am excited to learn more about this topic.
