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
