I think that Hadley CRUT did the same thing. Look at this chart of temperatures from 1940-1997, it is basically flat, very little warming. So if we plot Hadley from 1940 to 1980 there is no change in temperature trend. Then let’s plot satellite temp from 1978 to 1977 and that temperature trend is also basically flat.

If you look at temp this way, since 1940 – the beginning of the industrial age, the ONLY significant rise in temp was in 1998, and we all know that was due to El Nino when an enormous amount of heat was released from the ocean, and temps have been flat since.

GRRRRRREAT news! Why isn’t algore in prison?
Good stuff. You’re on a roll.
Notice that although the net adjustment is actually kinda small, from +0.3deg/century to +1.0deg/century, the bulk of it comes from much more, extremely more substantial “adjustments”, DOWNWARD, in the temperatures in the early part of the graph, particularly between 1900 and 1950.
From what I have read on this general theme in the past, that type of thing - UNDERVALUING either CO2 values or temperatures purported to be present at the beginning of some time period used by a “global warming” graph/mathematical construct/computer model - is part of what started this whole scheme to begin with.
