Start with a simple factor which you haven't mentioned involving the Earth's major greenhouse gas: water vapor. Increased temperature obviously encourages evaporation of water. Will that water stay as a gas, or will it cause greater cloud formation? Will those clouds be flat or tall? Look at today's weather satellite pictures -- are clouds an unusual event? What will cloud changes do to climate?
Which is exactly why the first half dozen or so parameters we checked out were cloud-related. Most climate change modellers acknowledge that there are large uncertainties around cloud-climate feedbacks, and these form a central focus of the experimental design.
