USHCN adjustments seem to show the increase is entirely made of adjustments?

The best bit is the final graph:

If you look at it, it looks very much like the increase in temps we have been told is going on. But it’s not. It is the changes made to the raw data sets to produce the ‘adjusted’ data sets.
Conspiracy? Where’s my working? Well, this is their graph, not an independent one! It comes from http://cdiac.ornl.gov/ itself.
So this tells us, in no uncertain terms, and completely unambiguously as far as I can see, that the increase of 0.6C is entirely fabricated. True I have not searched for a justification of that fabrication – it may be valid, but it should be reported as such!
