Having skimmed the final paper and without being aware of Judith Curry or her reputation, my initial reaction while reading was "This seems to be a white paper in the school of 'here's something you can cite to justify why nothing should be done about climate change/global warming/CO2 emissions/etc.'"

Looking her up afterwards, it seems to me that this may also be her push for a significant position in the Trump administration. Seems that Judith Curry is the scientist who says "Well, they've revised the likely range so clearly they don't know what's likely and maybe it's too expensive to do anything right now."

I won't bother linking, a simple search based on her name will turn up a wide variety of links to her history, people bemoaning her stances, and people refuting some of the arguments she uses.
