«The main driver of all weather and climate, the entity which occupies 99.86 % of all of the mass in our
solar system, the great ball of fire in the sky has gone quiet again
during what is likely to be the
weakest sunspot
cycle in more than a century,» according to Virginia - based weather forecaster Vencore Weather.
On balance the evidence shows that
solar and oceanic variations are more likely the cause of recent observations of warming in the air than increasing CO2 in the air but the issue can soon be resolved by observing the global air temperature changes that occur
during and after the extended
cycle 23 and the probable
weak cycle 24.
The cooling fears of the 60's and early 70's coincided with slightly
weaker (but still historically high)
solar cycle 20 and the recent cessation of warming occurred
during cycle 23 which has been slightly
weaker than the two
cycles before it.
The Milankovitch
cycles are
weak from the point of view of net
solar forcing, but they affect the albedo through systematic changes in northern ice cover
during the months when there is more daylight.
«This is the first time we have seen a short and
weak cycle since scientists began tracking the
solar cycle in the 1700s, following the last grand minimum in the 1600s when there were almost no sunspots... The big question remains: Are we about to head into a grand minimum, as happened
during the Maunder Minimum in the 1600s?
7.4.5.3 Synthesis Although there is some evidence that ionization from cosmic rays may enhance aerosol nucleation in the free troposphere, there is medium evidence and high agreement that the cosmic ray - ionization mechanism is too
weak to influence global concentrations of CCN or their change over the last century or
during a
solar cycle in any climatically significant way.
The full amplitude of
solar cycle forcing is about 0.25 W / m2 [64], [71], but the reduction of
solar forcing due to the present
weak solar cycle is about half that magnitude as we illustrate below, so the energy imbalance measured
during solar minimum (0.58 W / m2) suggests an average imbalance over the
solar cycle of about 0.7 W / m2.
The report which contains statements like this: «Although there is some evidence that ionization from cosmic rays may enhance aerosol nucleation in the free troposphere, there is medium evidence and high agreement that the cosmic ray - ionization mechanism is too
weak to influence global concentrations of CCN or their change over the last century or
during a
solar cycle in any climatically significant way.
The forcing from changes in total
solar irradiance alone does not seem to account for these observations, implying the existence of this unknown amplifying mechanism.The cosmic ray - ionization mechanism is too
weak to influence global concentrations of CCN or their change over the last century or
during a
solar cycle in any climatically significant way.
«there is medium evidence and high agreement that the cosmic ray - ionization mechanism is too
weak to influence global concentrations of CCN or their change over the last century or
during a
solar cycle in any climatically significant way.
Cosmic rays enhance aerosol nucleation and cloud condensation nuclei production in the free troposphere, but there is high confidence that the effect is too
weak to have any significant climatic influence
during a
solar cycle or over the last century.

What are your thoughts about how a
weak solar cycle occurs
during a swarm of highly intense
solar cycles?
