Bees control the ambient hive temps in the summer and I expect that once the
cluster begins to move and population growth begins they once more begin to
control the ambient temperature and humidity respectively.

They don't attempt to heat the hive, they heat the cluster. Heat outside of the cluster is waste heat. An example of waste heat is the heat coming out of your chimney. The presence of heat there is not an indication that you are trying to heat the whole outdoors, it is an indication of the inefficiency of your heating system. Beyond that, all that waste heat is contributing to global warming. In that respect, bees are smarter than we are. They don't heat their houses, they just bundle up.
