Termination Shock. Soluzione estrema

The book presents bold ideas for geoengineering and climate tinkering. I wonder if these reflect real possibilities or are more speculative?

The interactions between nations felt very plausible but also heightened for drama. I'm curious whether real-world conflicts influenced these portrayals or if they evolved during writing.
