For a totally uninformed opinion,(regarding instruments and their crafting) but I DO know from various crafts that different glues have different characteristics, including flexibility at various temperatures, resistance to moisture, resistance to mold and/or microbial action, etc, etc. So I suspect that yes, there would be certain climates that would affect an instrument adversly should the glues/varnishes etc on the instrument not have been chosen with the conditions of that climate in mind....
