Analyses of PFM and recreated temperature graphs in Chapter 8, indicates that the current global warming 231-year PFM cycle is expected to begin to decline between 2008 and 2014 with major declining of the PFM cycle around 2020-2024.

Further analyses indicate that the earliest date of 2008-09 for the initial phase of global cooling is attributed to the 9-year lunar cycle that is responsible for the twin 9-year temperature peaks that are seen within every global warming cycle. These peaks separated by approximately 72-years were clearly seen in each of the global warming cycles during the past 1,000 years.
The NASA United States temperature graph in Figure 30 confirms these findings. A 9-year temperature peak occurred from 1932 to 1940, followed by a 9-year period of cooling, then a minor warming peak over the next 5-years before cooling once again. One should note a very important 9-year declination cycle (4.63 x 2 = 9.2) controlling these cycles. As noted earlier, the approximate 9-year cycle occurs during the first half of each sub cycle of the 72-year PFM master cycle.
Further analysis of the NASA temperature graph indicates the second 9-year temperature peak of the current 231-year global warming cycle occurred as expected from 2000 to 2008, approximately 70-years following the beginning of the first peak in 1930.
This peak will be followed by a near 9-year cooling cycle, and it is this cycle that will signal the initial cooling phase for the ending of the current global warming cycle. This cycle will be followed by a minor 2 to 4 year warming (the 4.63 year PFM cycle), followed by an expected major and very rapid 30-year cooling.
