6) The origin of the current thermal imbalance

6) The origin of the current thermal imbalance

There are no more doubts that human activity at least shares some responsibility with regard to the current imbalance, but to develop a good understanding of thermal science, we will explore all possible hypotheses, including the most implausible ones.

Question

List all possible causes for an imbalance which could lead the temperature of "the house" displayed below, currently in thermal equilibrium, to increase.

An increase in temperature could correspond to:

  • - An increase in the heat received from outside (from the sun)
  • - A decrease in the heat emitted towards space
  • - An increase in the heat received from inside (geothermal energy, human activity)
  • - An increase in the Green House effect (which we will equate to a variation of the thermal resistance of the atmosphere)

Or to a combination of these multiple factors

Or to a combination of these multiple factors.

We can therefore list the following hypotheses:
