Not sure why you'd call this "fantastic" other than it's a feel-good book without any evidence to support it.
>Carbon emissions per capita are actually down [1]
It takes maybe 2 minutes, maybe upwards of 10, to realize why this is completely silly. I would expect most highschoolers in stats to rip this apart. Does anyone need to devote time to debunk this? Why? You can ask ChatGPT.
>Average figures can mask significant inequalities within countries. In many countries, a small percentage of the population may be responsible for a large portion of emissions, while the majority have very low carbon footprints.
If you don't understand why this negates your comment out right should I start quoting 2Pac?
Now you might argue that the data either doesn't support the claims made, or you might doubt its legitimacy, but instead of providing a reason you just told me that it should be obvious why the book is nonsense. That doesn't really give me a lot to engage with and I'm not going to try to make your arguments for you.
For me the Book had its intended effect. It argues that the climate movement, as it gained mainstream popularity, also lost its ability to convey nuance in favor of projecting a strong "we are heading towards certain doom" message. This helped grow the movement, but is also responsible for a lot of young people feeling completely hopeless. That's certainly something I could heavily relate with before reading the book. The book then goes on to highlight areas where the world has made much bigger progress than I would have thought. For me this turned a feeling of intense hopelessness into one of motivation.
So was the Book meant to make me feel good? Sure. In that sense I guess you can call it a feel-good book. Were the claims unsubstantiated and "without any evidence to support" them? Certainly not.
