It covers the typical problems associated with high temperatures but as with everything I've read, it assumes the RH changes with temperature. This is normal unless you have a closed environment that controls the RH taking temperature into the equation. Boveda does this. It will keep the RH from changing when the temperature increases. It will give off moisture as the temp goes up. The "relative" humidity will stay where you want it.
Now I'm not talking about quick changes. I'm talking about it going to maybe 80 degrees for a few weeks in the summer. That gives the Boveda or whatever system you have to catch up.
I don't think quick aging is a factor as I don't mean long term storage at high temperature. The idea that the oils dry out would be a problem but would this really happen if the RH remains in a good range.
I'm just thinking of all the people who have expensive cooling systems that may not be needed. I'm thinking that a few weeks at 80 -85 deg. may not be bad and that the problems are an old wives tale just like "plume".
Then again, I could be completely wrong
