Anyone know why caves might take time to return to its normal thermal values after mass tourism?

Answer 1

A couple of things can contribute... Firstly, caves maintain a temperature that is the average of the highs and lows for their geographic location. I give you the example of Lafleche Cave in Quebec Canada. Surface temeratures vary from 35 celcius in the summer to minus 40 in the winter. Inside Lafleche, the temp hovers between 3 and 8 degrees, no matter what time of year. So the cave environment is fairly stable, and things tend not to change too rapidly unless by human activity (barring natural disasters, of course).
Humans emit gases as they breathe, and also generate body heat, which contribute to elevating the cave`s temp. Because it is a static environment, it simply takes a long time for the system to get back to normal. This is a really simple answer; there are many other contributing factors, and each cave system is unique.

Answer 2

Yes, it is because of the thermal emitting heat that the tourism caused by entering the caves. With the thermal heat emitted at infrared spectrum, the cave will be heated and for a while, it will cool down as the infrared heat gets converted into another energy by absorbing the heat.

Answer 3

good insulation? thick walls and so on...
