«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.
Solar activity has increased from the early 1900's in correlation with temperatures, solar activity has not «quieted down» the current solar cycle 24 has been weak compared to solar activity during the latter half of the 20th cenSolar activity has increased from the early 1900's in correlation with temperatures, solar activity has not «quieted down» the current solar cycle 24 has been weak compared to solar activity during the latter half of the 20th censolar activity has not «quieted down» the current solar cycle 24 has been weak compared to solar activity during the latter half of the 20th censolar cycle 24 has been weak compared to solar activity during the latter half of the 20th censolar activity during the latter half of the 20th century.
