Perhaps we should tell Greta, Al Gore and their cronies this.
The sulphur dioxide that spews out of a volcano acts as a huge solar reflector that combats global warming.
If we had more volcanoes erupting we wouldn't have the problem of global warming.

First although clouds of various particles do indeed lead to cooling that can last for three years or more (which in itself could become problematic for obvious reasons) scientists have found that major volcanic eruptions accelerate ozone destruction.
Since the ozone layer is already known to be depleted it naturally follows that anything accelerating further depletion will also accelerate global warming.
Once the temporary cooling effect finishes, of course.
"Study of ozone amounts before and after the 1991 eruption of Mt. Pinatubo show that there were significant decreases in lower stratospheric ozone (Grant and others, 1994). The amount of ozone in the 16-28 km region was some reduced by 33% compared to pre-eruption amounts. A similar reduced amount of ozone was measured in the summer of 1992."

Second the introduction of further CO2 from volcanic eruptions obviously further increases global warming.
Now okay, compared to human-influenced CO2 emissions then even large volcanic eruptions have only a negligible impact but it remains that there is an impact.
When the Philippines Mount Pinatubo erupted in 1991 that alone emitted an estimated 50 million tons of CO2.
Add the extra CO2 from a number of large volcanic eruptions in quick succession to the depletion of the ozone layer and global warming could quickly become a catastrophic event.
In theory, of course.

I was reading somewhere very recently that the earth's magnetism may be undergoing another change and that this was what had wiped out lots of life on our planet in the past, including neanderthal man.
That has absolutely nothing to do with mankind's effects on the planet whatsoever and could be far more damaging.

Sulfur dioxide dissolves in water (usually rain) forming sulfurous acid. This falls to earth - usually into the oceans causing the pH of seawater to fall and become acidic. This acidic water kills off plankton and algae amongst other lower life forms. These dying off causes oxygen production to fall because they aren't using up the carbon dioxide during photosynthesis. Ultimately, it will be the lack of oxygen will be the end of us all, not global warming.

Volcanoes are the least of our worries.
