Process:  - Solar radiation reaches Earth's atmosphere - Some is reflected back into space - The rest of the energy is absorbed by land and oceans, heating the Earth - Heat radiates from Earth to space - Some of this heat is trapped by greenhouse gases in the atmosphere - Human activities such as burning fuel are increasing the amount of greenhouses gases - This causes more heat radiation to stay trapped in our atmosphere - The Earth's temperature rises -   Perturbation hypothesis: suppose more water has evaporated into the air happens, how will it affect more heat is trapped by greenhouse gases.  Does the supposed perturbation have an effect (direct or indirect) on the process?

no
