I only have one question, was this eruption "man-made"? If not, nothing man does can compete either positively or negatively. In other words, spending a single penny on "climate change" is a waste.
I had a discussion along these lines with a scientist (who grifted via academia for his entire career) whose son is completing a PhD is volcanology. The man with whom I spoke was dismissive of the fact that we (in the “West”) can never hope to offset the carbon emissions of China.
Said old man scientist - the glaciers are melting away rapidly because of climate change. Etc.
These people are divorced from reality.
