None of what you've listed changes the whole point, which clearly eluded you.

Scientific Consensus

The most prominent scientific bodies globally agree that industrial-era human activity has altered the atmosphere's composition, leading to global warming. Computer models show that observed rapid warming cannot be explained by natural causes alone, as the natural variability seen in tree rings and ice cores is too small to account for the changes of the last several decades.


And........

Do erupting volcanos contribute to global warming more than man's activities?

No, erupting volcanoes contribute significantly less to global warming than human activities. In fact, human activity currently emits approximately 60 to 100 times more carbon dioxide (CO2) annually than all of the world’s volcanoes combined.

Here is how the two compare based on scientific data:

Annual Emissions: Human activities (primarily burning fossil fuels) release roughly 35 to 40 billion metric tons of CO2 per year. In contrast, all volcanoes worldwide—both on land and under the ocean—emit an estimated 0.13 to 0.44 billion metric tons annually.

Scale of Impact: It takes humans only about 2.5 hours to emit as much CO2 as the massive 1980 eruption of Mount St. Helens did in nine hours. For volcanic activity to match human emissions, a Mount Pinatubo-sized eruption would need to occur twice every day.

Cooling Effect: While volcanoes do emit greenhouse gases, major eruptions often have a temporary cooling effect on the planet. This is because they blast sulfate aerosols into the stratosphere, which reflect sunlight away from Earth for one to two years.

Historical Context: Although volcanoes were major drivers of climate change over millions of years (such as during the formation of "large igneous provinces"), modern volcanic activity is far too small to account for the rapid warming observed since the Industrial Revolution.
