  General Notes
  1. The graphs on these pages are based on data extracted from the records of the University of Alabama (Huntsville) and available here. For notes about the data see the "readme" file in this folder.

2. On all graphs the year label appears in the January position.

3. My thanks to Dr. Wilson Flood of Dumfries, Scotland, for preparing these graphs

4. These plots use the latest available data from UAH and therefore include any revisions.

Figure 1(b) - Trend to latest month (shown as degrees/month)
  Comment: The trend is slightly upwards because of the recent El Nino, although the accuracy of the data at this number of decimal places is uncertain. (e.g. 0.0006 and 0.0015 will both round to 0.001)
