Why are there three different averages listed?

1.  The 1971-2000 is the current standard 30-year average time period. 
A new 30-year average will be calculated for the 1981-2010 time period

2.  The second average includes the years since 2000.

3.  The third average, 1950-2006 is the average for the entire data set.  It is lower due to the iclusion of the early years when data were under-reported.
