The Yamal data hockey stick  controversy overshadowed it, and much of the focus has been there recently.

The discovery of a Wikipedia graphic in the UNEP Climate Change Science Compendium must have been embarrassing as  it shows the sort of sloppy science that is going into “official” publications.
