Fantastic, thanks for the explanation. Can you please point me to a source? Need to send it to my dad who taught me everything I know but has now turned into a climate change denialist who says it's all a globalist / marxist / leftist plot to make money off solar panels.

Absolutely, and I wish you the best of luck in representing your views to your father. I know how painful such a disconnect can be.

This is a good intro to the broad issue of volcanoes and climate: http://www.cotf.edu/ete/modules/volcanoes/vclimate.html

A more in-depth treatment of sulfur aerosols in the upper atmosphere: https://en.m.wikipedia.org/wiki/Stratospheric_sulfur_aerosol...

Here’s a breakdown of all the gasses typically releases during eruptions and their various effects: http://volcanology.geol.ucsb.edu/gas.htm

If there’s anything else I can do, please don’t hesitate to ask.

Thank you so much! I will send them all three. Just because you offered and you seem so knowledgeable, he has also claimed the CFC damage to the ozone layer was a hoax created to promote alternative refrigerants... If you have anything on that I could use a link as well!

My pleasure, and I have a great link that goes into the exact mechanism of how CFC photochemistry destroys the ozone layer.

Here’s one with more technical analysis along with the exact chemistry:
