Default Global Warming increases lightning which increases volcanoes is there a link between global warming and more active volcanism

So I am looking for some link between Global Warming and increased
volcano activity. In Global Warming we increase world water by the
melting to the artics and ice all over the globe. But can an increase
in ocean water activate more volcanic activity? I doubt it, or I am
skeptical of such a big influence.


It turns out changes in sea level can affect volanos to some extent due to
the changed mass distribution. There are even a few volcanoes that are so
sensitive that you can see a correlation between their eruptions and local
weather (air pressure). However those are the exeptions so I doubt there
will be much of an impact from global warming.


I did not know some are that sensitive.


But what about the changes in the magnetic field of earth due to Global
Warming. The reversal of the poles or migration of the magnetic poles.
Could Global Warming affect magnetic pole migration which in turn
increases volcanic activity? That sounds plausible, but I see no direct
link. Until I see a link, I must abide with the idea that Global
Warming and Volcanoes are for the most part, independent processes.


The magnetic field is generated far down in the Earth, and I see no way it
could be affected by global warming on the surface.


Neither did I. However, I did not think much about it, but as volcanic
activity is increasing the world over, I must delve into this
possibility fully.

I wonder if lightning is a direct link between Global Warming and
Volcanoes.

Could it be that lightning bolts and lightning flashes increases as
Global Warming increases? Has any measured whether lightning has been
increasing in the past century? And does increase in carbon dioxide in
the atmosphere not only increase temperature but increases the
formation of lightning bolts?

And lightning would then discharge into the ground and affect Earth's
magnetic field. The Pole reversal of Earth is not well understood.
Perhaps lightning discharges from thunderstorms plays a key role in
where magnetic poles are.

So, now, let me try to draw a hypothetical linkage between Global
Warming and the increase in volcanic activity. As the Earth's
atmosphere increases in carbon dioxide, lightning bolts and lightning
flashes increase and where these lightning bolts are discharged into
the ground re-arranges the magma flow in Earth's mantle and core and
rearranges the magnetic poles. So increase in carbon dioxide increases
lightning bolts which rearranges magma and affects volcanic activity.

So is there any evidence of increasing lightning activity the world
over for the past 100 years?

Also, we can study planets like Venus which has volcanic activity, and
may or may not have lightning bolts. Or perhaps Europa or other astro
bodies.
