This section collects the subject branches that are best browsed as coherent libraries rather than forced into the main staircase of the core book. They are not minor side material. They are substantial branches of the wider project.

Snow, glaciers, permafrost, alpine hydrology, and mountain hazards form a distinct field-focused branch of the project.
Trade, transport, pipelines, pricing, and energy systems belong together as a strong human-systems branch beyond the gateway chapters in the core book.
Open these later, once the logic of modelling, uncertainty, and spatial analysis already feels familiar.
Some Earth observation foundations still live inside Environmental Systems for now, but they function as part of the wider remote sensing library.
