Global cooling on the way
How the Sun might change the climate
By Salvatore Del Prete
Areas of importance largely neglected are the solar wind speed , the global electrical circuit, and galactic cosmic rays . Actually they are all tied to one another.
When the solar wind decreases , the intensities of galactic cosmic rays (GCR) allowed into the atmosphere will increase, thus intensifying the global electrical circuit.
It has been shown through actual data on a short term basis (days) through the monitoring of Forbush decreases and SEP events – which stands for solar particle events – both of which originate from the sun , that the electrical circuit decreases following a Forbush decrease ( a lessening of galactic cosmic rays ) while it increases following an SEP event.
This has big implications for solar/climate relationships on a longer term basis because these day-today events have shown that when a FORBUSH DECREASE take place the global electrical circuit decreases. This results in a decrease in global cloud cover and a weakening of cyclonic systems, while the opposite follows an SEP event.
This can be applied to what happens to global cloud coverage and cyclonic systems over a long-term basis when the sun enters a prolonged solar minimum period of activity which lowers the solar wind. This allows more GALACTIC COSMIC RAYS to enter the earth’s atmosphere thereby increasing the strength of the global electrical circuit. This has been shown on a short term basis (through actual data ) to increase cloud coverage and strengthen cyclonic systems.
350km/sec or lower is needed for the solar wind speed in order to get Galactic Cosmic Ray counts high enough ( at least 6500 units ) which strengthens the global electrical circuit on a long term basis. This in turn promotes greater global cloud coverage and strengthens cyclonic systems. Higher albedo for sure, and perhaps more precipitation.
In the meantime EUV (100 units or less) /UV light is on the decrease which will effect the atmospheric circulation (more meridional ) and sea surface temperatures respectively.
All this will lead to global cooling
Getting back to the solar wind and it’s effects upon the climate: These two values are needed in my opinion which are again a solar wind speed sustained over months of less then 350km/sec and a resultant AP index over months of 5 or lower.
Solar irradiance will not be a major player in the changing of the climate. It may drop by .15% which would only contribute a .1c to maybe .2c to global cooling.
AS OF NOW GCR COUNTS HAVE BEEN ABOVE 6500 UNITS FOR A FEW MONTHS AND LOOK TO BE INCREASING. READING TODAY 6650 UNITS, AND THE SOLAR WIND HAS FINALLY STARTED TO COME DOWN RIGHT NOW AT 300KM/SEC ALONG WITH THE AP INDEX.
Will this persist and become more common place as we move forward? I say yes, and this should effect the climate by cooling it.
