Your approach is one of either willful ignorance or deliberate obtuseness. You cannot separate the paper from its PR. The PR focuses on the uptick wrongfully shown in the headline graph – an uptick that was obtained, apparently, through deliberate manipulation of certain datasets, as show in McIntyre’s analysis and nicely summarized and explained above by Rud. Examples of the PR are shown here:

The latter headline is from Revkin – who should know better.
So far, what we have is a relatively unexceptional plotting of early Holocene temperatures. The resolution of that plotting makes it impossible to determine whether there were any centennial (or less) temperature swings during periods such as the Minoan, Roman or Mediaeval warm periods. In fact, as you yourself argue in this thread, the study shows nothing about modern warming. The lack of resolution, however, means that you cannot compare their graphing of the early Holocene with the 0.7 – 0.8 degree C. temperature change experienced over the course of the 20th century. As Robert Rohde noted in discussion with Revkin:
“The 20th century may have had uniquely rapid warming, but we would need higher resolution data to draw that conclusion with any certainty. Similarly, one should be careful in comparing recent decades to early parts of their reconstruction, as one can easily fall into the trap of comparing a single year or decade to what is essentially an average of centuries.”
The temperature spike shown at the end of their “headline” graph was only obtained through apparently deliberate manipulation of core top dates – manipulation that resulted in excluding some data while including other. Neither the paper nor its SI includes any justification for this re-dating: while a general assumption was given (i.e., core-top dates were to be assumed to be 1950 unless otherwise provided in the source), they have changed the dating of core tops which have clear and well defined dates. Those changes were made without explanation and only by doing so, were they able to obtain the apparent temperature spike at the end of the graph (one which actually does not correspond with measured temperature changes, given that their study date stops mid-20th C).
This approach and manipulation of data should be condemned not condoned.
