Note this excerpt from "EXPECTED HALT IN THE CURRENT GLOBAL WARMING TREND?":
The mean variation in Fig. 3 (shown by a smooth solid curve) clearly oscillates from 1856 onwards. This oscillation displays maxima in the years 1878 and 1942 as well as minima in the years 1909 and 1971. This series of maxima and minima indicate presence of a dominant oscillation with a mean period of 63 years. Simple forward extrapolation of this dominant oscillation shows that the next maximum will expectedly be in the year 2005. On this basis, some global cooling trend is expected to start in about 2005 and last up to about 2036. By coincidence, the latter year is approximately equal to the earliest year (arrived at in Section 3) at which some cooling trend over Greenland is expected to stop. Finally, it should be noted that the period of the 63 years oscillation mentioned above (in connection with global mean temperature) is equal to the period of the second harmonic of the sunspot oscillation shown in Fig. 4 using a series of x's. The theory and mechanisms through which the latter sunspot oscillation so significantly relates to global mean temperature variations are given in Refs. [9], [14] and [15].
