In fairness, climate change does not increase volcanism...

I was referring to the weather extremes. The point is that you don’t need the Hunga Tonga eruption to explain those. Moreover, at this point it's pure conjecture that the eruption would constitute a major factor here.

Of course that climate change will increase volcanism. Is the most logical outcome. Well, I'll self-correct myself: Replace "will increase" by "has been increasing".

  Volcanism isn't caused by the climate, it's caused by magma seeping up from the Earth's core through cracks in the mantle.

        The fact that the earth crust is floating in the mantle over a sea of magma And how much it floats or sinks is directly linked with local gravity... gravity that is a reflect of the thickness of the crust in that area. Or if we prefer of how much matter is accumulated in that local area. The thicker, the heavier, so the crust will sink more by the force pointing down that come from its own weight and local gravity in the area will increase ... Can you see yet where this is leading us, and why I'm 120% sure that climate change WILL come with an increase in volcanic eruptions?

        > Can you see yet where this is leading us, and why I'm 120% sure that climate change WILL come with an increase in volcanic eruptions? Melting of ice sheets on Greenland and Antarctica causing land to rebound (called iso-something shock IIRC?) which is likely to cause all kinds of tectonic activity such as volcanism. Which is less weight on the crust there, and so a lower local gravity in those areas. Gravity isn't strong enough to do much to even the thinnest part of the crust (about 16km in part of Antarctica apparently) directly unless you just mean it as weight, which is a weird way of using the term.

        Finally. Sometimes I feel like I'm talking to a wall. Gravity was introduced to talk about why we know that North and South Poles will behave in a different way, but you are right. Forget that part. So there is a direct link between climate change and an increase in volcanoes activity and is easily observable. We can expect an early spring activity in the North Pole, adding forces than then will typically trigger a "ping-pong" chain of volcanoes around equator and in the opposite areas of the planet. Has been happening for a while yet

Nope! Just like the pandemic didn't increase earthquakes. But, when you're in the middle of one crisis, it makes a second crisis even more devastating.
