Most of the time, the official line is that volcanoes don’t generate enough CO2 to affect the climate. But occasionally the story is changed to suit the agenda.
Penn State study ties high volcanic CO2 release to prehistoric climate change

Prehistoric evidence offers proof that high carbon dioxide levels in the atmosphere cause global warming.High carbon-dioxide levels in Earth’s atmosphere 55.9 million years ago caused average temperatures to increase by 9 to 16 degrees Fahrenheit, a Penn State University study concludes.
That means fossil-fuel burning that’s filling the atmosphere with high levels of carbon dioxide could raise temperatures dramatically in a process already under way.
In the study published in Nature Geoscience, Lee R. Kump, Penn State professor of geosciences, said Norwegian core samples reveal that volcanic activity that burned accumulated carbon-based materials 55.9 million years ago increased the rate of carbon emissions into the atmosphere by a factor of about 100 over background volcanic rates.
Right – they are claiming that normally there isn’t much limestone or organic material in the ocean near subduction zones. ROFLMAO
The warming is from the hot cash burning a hole in their pockets?
Would anyone like to comment on the veracity of the claims in this post , “Why volcanism isn’t the source of increasing carbon dioxide emissions” , by Erik Klemetti, for whom, I hasten to add, I have the greatest respect.

Perry,
SUYTS and I think maybe Mike (or was it Latitude) provided some interesting peer reviewed papers that suggest possibly significantly higher levels of CO2 from submarine sources than Gerlich has stated. There was no indication from those papers that it approached the levels needed to to equal human sources, but it seems clear to me that this is an area where much more study needs to be done.
This is Quantum Science.
Volcanoes only affect the climate when no one can see them.
So past volcanoes were relevant.
Once a volcano is observed, it ceases to be climatically relevant and can be quantized down to -infinity of CO2.
Yet CO2 explains all natural phenomena
