The Graft Problem

Over at Climate Skeptic, I discuss the problem of graft.  No, not bribery (though I do have a beef with the industry cabal that supposedly funds all skeptics for not coming through with my check).  In this case, I discuss temperature reconstructions that graft one data series onto another, and try to draw conclusions about the inflection point which, suspiciously, occurs exactly at the spot the two series are spliced.
