B)positive feedback
C)neutral feedback
D)adiabatic feedback

Question

Quizplus · Accepted Answer

This is an example of a positive feedback loop, where the initial change (increasing temperatures) leads to an amplification of that change (increasing water vapor amounts leading to increasing absorption of longwave radiation), which further enhances the initial change (increasing temperatures). This can lead to a runaway effect, and is a key factor in the amplification of global warming.
