Fascinating idea, and plot. 10/10 in the first half. Loved the way the author unfolds the first decades. Also loved some of the very technical but also very well explained solutions proposed. Disappointed but not disagreeing that we will need increasingly negative incentives alongside leadership and economic invectives to tackle climate change. My interest in the book dropped significantly towards the end, but if you think about it it's an extremely hard book, plot and story to wrap up.
