After adding greenhouse gases to the atmosphere, do climate models have an overall positive or negative feedback with respect to changes in global average temperature? In other words, is the predicted temperature change larger or smaller than the non-feedback case?Which particular feedback processes in the models' representations of the climate system are most responsible for this overall feedback? In the reading, it is stated that current climate models have a difficult time correctly simulating these particular feedback processes.In evaluating the predictions that climate models make in response to human emissions of greenhouse gases, why is it important to consider that the feedback processes responsible for much of the predicted future warming resulting from greenhouse gas emissions by climate models are some of the processes that are most difficult for the models to properly simulate.
