  2. CO2 isn’t a major gas emission from volcanoes. The gas part is mostly sulfur dioxide (not a greenhouse gas). Scientists estimate that volcanoes worldwide emit about 1.5 million metric tons of CO2 per day (only about 2% of the amount that human activity releases per day). We know this because the Keeling curve doesn’t budge when there is a major eruption. A super volcano eruption might change this a bit.

  3.  @maka6542  Maybe Fanta is Italian. Vulcano is Italian island near Sicily that has an active volcano. I'm not sure if it gives performances these days. I think the last notable eruption was around 1900.

  4. A fraction of a degree C warmer at the ocean surface and almost no change at the ocean floor. I don’t think so.

  5. ​ @pepsilon3210  Good suggestion. Or even better, use non-polluting energy sources. There are an abundance of these, at almost the same cost too, or even cheaper sometimes. The planet is not in any danger, but modern civilization is at risk. We will run out of the polluting kind of energy eventually in the not too distant future. Why wait until civilization collapses?

  6. ​ @neutronalchemist3241  I went through the numbers recently with someone else. About 50,000 tons of atmosphere are lost each year (37,000-78,000 tons). Or 100,000 tons depending on the source you use. At this rate of loss it would take about 55 billion years for the Earth to lose its entire atmosphere. Remember that the universe is less than 14 billion years old and the Earth itself is just 4.5 billion years old. It is mostly hydrogen and a little helium that is being lost and volcanoes emit negligent amounts of these two gases, which is why they are both trace gases in our atmosphere. But volcanoes emit 200 million tons of carbon dioxide and we emit about 24 billion tons of CO2 emissions every year worldwide, plus volcanoes emit 20 million tons of sulfur dioxide, so the atmosphere may change but it isn’t going away anytime soon. Note: most of the natural CO2 emitted is either reabsorbed or turned into oxygen by plants and about 2/3 of our CO2 emissions are reabsorbed but the conclusion above is unchanged.
