Given these trends, we decided to revisit the issue of teacher diversity, and we calculated again our groundbreaking «Teacher Diversity Index,» an approach we pioneered in our first paper that ranks states on the percentage - point difference between teachers of color and students of color.

If we chose to calculate per decade (one data point) we would lose all the information about the trend.

Boris (# 121) points out that contrarians are more than happy to accept the trends calculated for a few distant planets if it obscures the cause of the trends seen on Earth — even though the data which we have on those trends have a great deal more uncertainty associated with them (see Nicholar L's # 88), and as an explanation in terms of solar variability is not credible (ibid.)

If you measure the temperature at 5.40 am and 7.40 all you have is 2 data points — not enough to calculate a regression trend.

In Part 1A and Part 1B we looked at how surface temperature trends are calculated, the importance of using Temperature Anomalies as your starting point before doing any averaging and why this can make our temperature record more robust.

The anomaly is better for calculating trends because it cleans up the end points making the slope insensitive to the start and stop point of the annual cycle.

Chart # 1 had 1919 - 1943 anomaly plot adjusted to start at same anomaly point as 1991 - 2015 period; chart # 2 linear trends are based off plots of chart # 1; chart # 3 uses 5 - year averages calculated from each period's anomaly dataset and then the 1919 - 1943 5 yr average was adjusted (i.e. offset) to start at same anomaly point as 1991 - 2015 5 yr average; chart # 4 cumulative differences calculation: the December 31, 1943 anomaly minus the December 31, 1918 anomaly and the December 31, 2015 anomaly minus the December 31, 1990 anomaly (both calculations covering a full 300 months).

As a result, these two years may be used as start and end points in calculating the global warming trend:

Those of you who want to calculate the trend of a profile after a peak by selecting a starting point before the peak must understand that you are not calculating the slope of the profile but the slope of the tunnel that starts from one side of the peak and comes out on the other side of the peak as shown in the following sketch.

These were used for comparing troposphere and surface trends in the CCSP report that is a reference point for both Douglass and Santer, as shown in their Table 1 below......

Similarly, I calculated the linear trend observed at the end of each decade based on Mauna Loa data (subtracting data points 10 years apart, multiplying by 10 to arrive at the century rate of change): 1960 - 1970 = 85 ppmv / century 1970 - 1080 = 128 ppmv / century 1980 - 1990 = 157 ppmv / century 1990 - 2000 = 153 ppmv / century 2000 - 2010 = 193 ppmv / century
