HADCRUT4 is now at its 3rd iteration. It started with version 184.108.40.206 and then version 220.127.116.11 come out. As of the latest data it is at 18.104.22.168.
I thought I would compare them. Here is the difference between them ( 22.214.171.124 monthly anomaly minus 126.96.36.199 monthly anomaly).
If the bar is red, the newest HADCRUT4 is warmer. If blue, then the newest data is cooler.
This is the data from 1950 on. Note that the values are pretty low and relatively evenly divided between blue and red.
Until 1997. Then the values are a little larger (still relatively small). And almost all red.
They are warming the most recent temperatures again! Give them a few years and the pause will disappear.
