Ironically, Mann's carefully
plotted uncertainty bands were not visible on the presentation graphic, just as they were not reproduced in Fred Singer's NIPCC report.
If we do this with the data here, we obtain an ECS that likely lies within the blue
band: between 3.1 and 4.2 K, with a most likely value of 3.7 K. Simply looking at the scatter of the 29 models in this
plot indicates that this
uncertainty band is too narrow.
