Ah! I assumed the problem was condensation on the inside of the dome dripping on the business.
Did you put your dome on a concrete floor or wooden deck, Dave? I can't remember... I would expect the thermal mass of a concrete slab to work with you help the inside of the obs cool slower (as well as there is no cooling air underneath).
If its on the wooden deck, you could excavate underneath, and make it a kennel for lots of dogs. Just make sure the floor is well sealed...
That should keep it warm.
