The assessment based on these results typically takes into
account the number of studies, the extent to which there is consensus among studies on the significance of detection results, the extent to which there is consensus on the consistency between the observed change and the change expected from forcing, the degree of consistency with other types of evidence, the extent to which known
uncertainties are
accounted for in and between studies, and whether there might be other physically plausible explanations
