Specifically for Kodachorme at Arizona temperature you would lose about half the life of the slide assuming humidity at 80%. Color loss was pretty linear with a small cyan crossover so reds would increase somewhat. In a practical sense you would lose saturation. A key point though is humidity is a necessary catalyst up to a point. In summary, if your slides were taken on old Koadachrome stock they should look unchanged for about 35-40 years in un-air conditioned space assuming old Arizona climate before everybody watered the lawn and put in swimming pools.
