«What is generally required [for proving solar forcing of climate change] is a consistent signal over a number of cycles (either the 11 year sunspot cycle or more long term variations), similar effects if the timeseries are split, and sufficient true degrees of freedom that the connection is significant and that it explains a non-negligible fraction of the variance.»
, but a suggestion for avoiding coupling shock: take a large number of model runs; for each assign a location in some n - space for indices of the more important modes of (internal) variability (but maybe also include indices for timing relative to and magnitude of eruptions, solar cycles, etc.).
The correlation between the two quantities is 0.85 with p < 0.01 for the whole period studied.It could therefore be concluded that both the decreasing correlation between sunspot number and geomagnetic activity, and the deviation of the global temperature long - term trend from solar activity as expressed by sunspot index are due to the increased number of high - speed streams of solar wind on the declining phase and in the minimum of sunspot cycle in the last decades.»
The number of sunspots is a proxy for the solar cycle change.
During the period 1950 - 2000, the average length of the solar cycle is 10.7 yr (using either the sunspot numbers, or the TSI reconstruction of Lean 2000, GRL 27, 2425).
The solar cycle that began in 2008 will reach maximum in 2013, but that maximum is predicted to have only one - half of the number of sunspots seen in the previous cycle.

They also fail to mention that although the incoming solar radiation only varies by a couple of Watts per square metre over a solar cycle the apparent smallness of the variation is a result of the small area subdivision and not any indication of a small total energy variation when one takes into account the number of square metres on the Earth's surface.
... these timescales is the 11 - year solar cycle, defined by the waxing and waning of solar activity as seen in the number of sunspots.

Unfortunately, our number will reduce when the cooling solar cycle starts.
The Hoyt & Schatten reconstruction used by Soon is not based on ANY measurements of solar radiation, but on [dubious] guess work extrapolated from solar activity proxies: «These indices are (1) the equatorial solar rotation rate, (2) the sunspot structure, the decay rate of individual sunspots, and the number of sunspots without umbrae, and (3) the length and decay rate of the sunspot cycle
There are some missing data for the period 1818 - 1849, and the data for SC10 - 11 are under revision, but all in all this graph conveys pretty well that - in general - a low amplitude cycle is preceded by a solar cycle transition with a high number of spotless days, and vice versa.
For some unexplained reason there have been a large number of coronal holes on the surface of the sun, in low latitude positions during solar magnetic cycle 24, however due to the reduction in the solar wind density the solar wind bursts have less effect on cloud modulation which explains why there has suddenly be an increase sea ice in the Antarctic, a recovery of sea ice in the Arctic, and an inhibiting of the formation of El Niño events.
