The Ministry for the Future
A : book
Author : Kim Stanley Robinson
Paints an incredibly grim picture of a world experiencing climate breakdown and the political ramifications. The opening chapter of a deadly heatwave in India is absolutely brutal. This is what climate crisis means.
Lots of didactic bits along the way. Some reviews say these are a bit tedious, but I've found them fairly positive so far - you learn from them. It does have a pretty stilted narrative flow as a result though.
It is hard science-fiction. So much that you might call it scientific utopianism. Though I don't know how much Robinson actively wants things to play out this way. (e.g. is he down with the acts of eco-terrorism or just thinks it will likely happen regardless).
