But for journalists and others who are not climate scientists, some narrative would help, as inline text and more clarification as footnotes if needed including, cover for
example: — being very clear for a graph what was being forecast (people play silly games with Hansen, confusing which was BAU)-- Perhaps showing original graph first «This is what was predicted...» in [clearly a] sidebar THEN
annotated / overlayed graph with «And this is how they did...» sidebar — placing the prediction in context of the evolving
data and science (e.g. we'd reached 3xx ppm and trajectory was; or «used improved ocean model»; or whatever)-- perhaps a nod to the successive IPCC reports and links to their narrative, so the historical evolution is clear, and also perhaps, how the confidence level has evolved.
