Typically, volcanic eruptions have a cooling effect. One of the principle emissions is sulfur dioxide which reflects high frequency solar energy (green house gases absorb and convert that same radiation into longer wave energy which excites atmospheric gases).
Volcanoes typically erupt with a lot of ash which blocks the sun and cools the planet. Get a big enough volcano and the earth stays cooler for years, disrupting crops and creating a potential famine.
Doesn’t increased volcanic activity cause an increase in global temperatures?

So, what you’re saying is, we can just piss off Surtr, just the right amount, and cancel global warming?
That sounds way easier than getting a giant ice cube!
The sum total of 33 actively degassing volcanoes in the world results in 60,000,000 tonnes of CO2 emissions per year without undergoing any eruption.
We could use a little ice age to go with.
