It is interesting that these super storms like the one in 1921 seem to  happen at times of  extended and  widespread heat and drought.   Some say this is evidence that the sun has been driving the climate.  But the widespread heat and drought precede the events.  Another possibility is that the dry ground and air caused  a buildup of voltage in the upper atmosphere and on the telegraph lines causing the extraordinary Aurora and telegraph disturbance.  The clear atmospheric conditions would also make observations of the sun clearer and make it easier to see activity on and around the sun.  An ordinary solar flare would be observed as something extraordinary.  The coinciding conditions that make up the solar proxie arguments for solar dominated climate tend to have these same problems.  Sudden declines in sunspot numbers coincide with cooling in the early 1800's and 1880's and 1960's.  But these declines also follow large explosive volcanic  eruptions.  Tambora in 1815 occurs after the cooling  and decline in sunspot numbers.  But a lesser known mystery near VEI7 eruption  recorded in ice cores about 1807 and the eruption of Mt. St. Helen's in 1800 are not as widely known.  A VEI7 explosive eruptions like Tambora occurs about once every thousand years.   One might suspect that sunspot visibility issues are involved.  Sunspots are counted as more ir less than one sunspot based on their size.  Sunspot numbers are a global average from all sunspot counters.  Some sunspots last only hours or minutes.  Some sunspots are barely visible even with modern viewing equioment.
Be10 and C14 created in the upper atmosphere by cosmic rays show a good correlation with temperature leading some to argue for the solar activity climate theory.  But volcanos throw large amounts of dust into the air.  Lighter than air .  Be10 and C14 are said to be transported to the surface by dust and water droplets where the Be10 and C14 are trapped in ice that makes up ice core records. 
The good correlation between cloud cover and temperature has a certain issue.  Which graph leads which? 
The solar activity theory says that the sun's magnetic field modulates  cosmic rays which modulates cloud formation which modulates global temperature.  But many things determine cloud cover including temperature. The max and min on the temperature graph lead the cloud cover graph.  
There is a good correlation between cooling and the passage of the earth through the spiral bands of the galaxy which is attributed to cosmic rays.  But one  might also expect increased cosmic dust and debris and probably comets and asteroids which also contrbute to clouds and cooling. 
The earthquake theory is not afflicted by these problems.  The earthquake graph clearly  leads the temperature graph.  One might expect the heat from a magnitude 9 earthquake concentrated in ocean currents to melt a lot of ice.  A magnitude 9 releases enough heat energy to melt the Arctic Sea ice in its entirety multiple times over.  This is according to the Moment Magnitude earthquake rating scale which has largely replaced the Richter scale since the 1970's.  A geologist named Tom Hanks developed the new earthquake rating system.  Another Tom Hanks starred in a climate disaster movie that involves catastrophic solar activity.
