Jones 1998 showed that all Northern Hemisphere warming occurred before 1940, and recent temperatures were similar to the MWP.
The graph below shows just the recent portion.
But Phil has changed all that, and now shows that essentially all warming occurred after 1970.
The next graph is an overlay showing the current CRUTEM (red) on top of 1998 Jones.
You can see how Phil removed the 1940’s blip, and created a hockey stick after 1970. Then he deleted all his E-mails related to this.

It would be good to remove at least part of the 1940s blip, but we are still left with “why the blip”.
Can you delete any emails you may have had with Keith re AR4? Keith will do likewise… Can you also email Gene [Wahl] and get him to do the same? I don’t have his new email address. We will be getting Caspar [Ammann] to do likewise.
