Before I left on my trip to New York, I published part 1 of this series looking at the temperature anomalies between the 4 global temperature metrics from 1979-January 2008. The first post I made on the subject used the unadjusted global temperature anomaly data to do the comparisons. I also wanted to do the same comparisons using anomaly data adjusted to a common reference baseline. But unfortunately ran out of time to complete all of the histograms for the next data set before I left on the trip.

In the meantime, while I was traveling, the first post, missing the all important part 2, generated some controversy, and some accusations that I was misrepresenting the data by not showing it adjusted to a common baseline.

It was a mistake on my part to not have them both available at the same time, and for that I apologize to anyone whom was misled by the lack of part2. Atmoz did a quick study of the issue also and illustrated what I wanted to do for part2 with a simple graph, and while it would have been easy to simply use his, I wanted to complete what I started using the same presentation style. Recognizing that an part1 only was misleading to some, I put part 1 back on the shelf until I could return from my trip and finish part 2, so that I could show what happens when all four metrics are adjusted to the same base period.

That is complete, the Part1 article has been restored, and below is the new adjusted information as it compares to part1.

Here is the first graph, the unadjusted raw anomaly data as it was published in February by all the above listed sources. Note that while there is pattern agreement to the 4 metrics, there is an amplitude difference.  Read rest of story...
