This is the third Ghosh book that I read this year, and let me say, finally! I guess his true potential lies in lectures, not novels. His points are very basic, but interesting and easy to read. He explores mainly the Asian pov in climate change (as a victim and as a culprit).
The book is divided into three sections: Stories, History and Politics. In each of them he analyses how climate change came to be and how these areas are dealing with it. Spoiler alert: they're not, and that's exaclty what he is criticizing in this book. He basically says that we are all deranged because we chose to ignore climate change willingly. And the worst part is that we know what is happening, what is going to happen, and we still do not act on it. I mean, no individual actions, obviously, but collective actions, laws, agreements, policies.
He also focuses a lot on how literature has ignored this issue for decades, not portraying what is actually happening to the world - which is another symptom of this collective derangement we are all suffering from.
It's a quick read, however dense and full of references. Not too difficult, tho. If you're interested in the climate crisis, the environment, you should read it!
