We're probably too early for dugout canoes, though we could definitely have rafts! I'd like to also take a moment to talk about climate and ice ages. So far, we have gone in and out of easily half a dozen ice ages. This has been an implicit thing, but not a point I devoted much attention to the cycle of warm and wet periods to cold and dry periods. So far, there have been a little over a dozen ice ages since this NES began. When an ice age happens, the climate bands shift (for us, they move north), the deserts expand, and the mountainous areas become glaciated. Polar ice sheets advance up to the edge of the mountain range that separates the Mkyaph from the Temekyap. On the Gero Coastlinee, from the mouth of the Akger River to north of the Abhwal, the ocean retreats, revealing up to 2000 kilometers of previously-submerged continental shelf. People migrate out onto these lands as they dry, and then steadily migrate back to higher land as they flood again. The change is almost imperceptible, and certainly not cataclysmic. When the ice ages end, the seas rise again, the glaciers retreat, and climate bands shift back southwards. The deserts retract deeper inland and to the west, while temperate zones spread. For the most part, people are able to adapt to these conditions by migrating back and forth of the generations. Less mobile people tend to adapt by altering their practices to deal with the changed conditions. If anyone has some specific questions about our world and its climate, I'd be happy to answer!
