hey how you all doing? Can anyone tell me 2 scenarios that could possibly lead to no overall change in GMST in this way.

 

(1) The fraction of Earth's surface covered with ice and snow decreases while the albedo of the surface (which isn't covered by ice and snow) decreases.

 

(2) The atmospheric CO2 concentration decreases while the solar constant increases.

 

(3) The volcanic aerosol content in the atmosphere increases while the atmospheric H2O concentration decreases.
