Could you support your assertion that the variation shown in the graph is due to volcanic activity? To me it looks like "steady increase after WWII, up to critical levels, then subsiding after the clean air acts of the 1970s". But I have no background in the subject.

- hasbroslasher 10y agoSure, here's a really simple one: https://www.metabunk.org/sk/Volcanic-activity-1945-2015.png https://www.metabunk.org/sk/Volcanic-activity-1945-2015.png Interestingly, this graph shows volcanic activity declining after the passage of the clean air act - perhaps the gods of volcanism heard our pleas. In all likelihood, yeah, it was a combination of the two factors, but it did bug me that they ignored below-average global volcanism post 1970.
- wycx 10y agoGlobal volcanic activity is an imperfect proxy, however. For instance, about 20% of present day global volcanic SO2 emissions are from a few volcanoes in Vanuatu (Yasur, Lopevi, Ambrym, Ambae, Gaua and Vanua Lava).
