"Expose: David Rose does not understand baselines"

David Rose’s article also includes the figure below, which purports to show that the NOAA data was adjusted to show higher temperatures. Well, this is immediately odd in that the issue is really the trend (i.e., how fast is it changing), not the actual temperature values. Also, the difference is almost entirely because NOAA presents their temperature anomalies relative to a 1901-2000 baseline, while HadCRUT4 presents theirs relative to a 1961-1990 baseline. If you shift them to have the same baseline, the discrepancy goes away. The immediate conclusion one might draw is that the figure below is intentionally misleading, but I wouldn’t rule out the possibility that David Rose simply does not understand the concept of a temperature anomaly, despite have written many articles about them.
