Long-term we could plant massive new floating plant species in the atmosphere to decarbonize it and form floating soil layers, which eventually would compactify and metamorphosize and spread out latitudinally to form a ring around the planet, thinning out towards the poles and making cliffs and beaches and islands with the atmosphere. The growing regions would not actually stay together but break apart and move technically on top of the atmosphere, with plate boundaries and subduction zones and volcanoes, driven by the pressure below, surface volcanism proper, and weather around the coastal areas.
