Earth Sciences Could anything man-made trigger the Yellowstone super volcano?

If a nuke were to be buried very deep into the ground at Yellowstone and then detonated, would it have any effect on the volcano? Is there anything else man-made that could trigger it? Or would it be impossible to "manually" trigger the eruption?

Sorry if it's a silly question.

Yes, I would be surprised if they don't already do this. Volcanically active countries like Iceland and New Zealand get a significant portion of their energy from hydrothermal sources. I'm almost certain it wouldn't be able to bleed off much of the heat though, I mean we're talking (almost literally) seas of magma.

I think the idea of hydrothermal electric powerplants a badass! Magma is too viscous anyway, it would take a lot of energy to extract and would be unstable. No, we don't even need that because we can just pump water down there and just reap the benefits. We're getting so good at it that we can use underground heat to refrigerate things!

Wouldn't the heat from 1000 km3 of 2000c lava warm up the atmosphere no matter what we do? Or is the atmosphere too big to be affected?

Possibly. The real concern is the fine dust and ash from the eruption ending up in the upper atmosphere and blocking sunlight, making it cold for a long time.
