Current conditions are so favorable for the GOP — including the president's poor poll
numbers, the states with Senate races, the lower turnout of Democratic groups in midterm elections, the quality of this
cycle's Republican Senate recruits and the daily dose of negative news that should help the party not holding the White House — that Republican Senate gains of fewer than six seats would be a punch to the party's
solar plexus.
The sun goes through an 11 - year
solar cycle during which its luminosity varies according to the

The
number of sunspots varies as
solar magnetic activity does — the change in this
number, from a minimum of none to a maximum of roughly 250 sunspots or clusters of sunspots and then back to a minimum, is known as the
solar cycle, and averages about 11 years long.
The majority of science work on the principle that the Sun is self modulating and each

«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.
«Going back to 1755, there have been only a few
solar cycles in the previous 23 that have had a lower

solar cycle, defined by the waxing and waning of
solar activity as seen in the
number of sunspots.

solar cycles in the previous 23 that have had a lower
number of sunspots during its maximum phase,» according to Vencore.
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

Unfortunately, our

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.
Thanks to an unusually quiet
solar cycle and an unusually high
number of volcano eruptions, global temperatures have been falling.
This page contains graphs and tables on the accumulated

By this point in the
