There is Paris Agreement, most countries signed including Italy and US. Detonating nukes and releasing several gigatons of CO2 is more dangerous than supervulcano.
Naturally released CO2 is harmless. There is a difference!

Eh? You are aware that if Yellowstone were to erupt it would literally mean the destruction of the United States. How is "defusing" the vulcano by detonating nukes "more dangerous" exactly?
>>Naturally released CO2 is harmless.
Again, atmosphere doesn't care - CO2 is CO2. Yes it doesn't count towards calculations that we currently do to model climate predictions, but it's not harmless, and a supervulcano event will fuck everything up, it doesn't magically stop having an effect just because it's natural.
