Yes, moisture and high humidity can cause mold.
Obviously, I like to keep my humidity and temperature levels over here in check.
What helps:
- frequent ventilation;
- a temperature- and a humidity-meter (Inexpensive available at your local hardware/DIY store.)
- a dehumidifier;
- more or less constant room temperature. (Eg don't let the temperature drop too much during the night to save heating costs.)

As a musical term for sure, "the '80s" imply the late '70s and early '90s. You can think of them as tapers of this golden decade.
