What Would Happen if All the World's Volcanoes Erupted at Once?

[@VosperCDN]

So all the nuclear weapons detonating are "better" than all the volcanoes .. thanks nature.

[@AndrewD8Red]

There aren't really enough nuclear weapons to cause a mass extinction. Don't get me wrong, a nuclear war would, at the very best, cause "only" hundreds of millions of deaths, though the actual death toll would likely be over a billion.

Glad the writer included the Siberian Traps as I plan to use the event to write my senior thesis. A quick correction from newer data (Vinnik, L. P., Oreshin, S. I., & Makeyeva, L. I. (2017)) puts the conservative estimate of CO2 released at 68 Gt between the degassing of carbon deposits (burning of coal) at the time as well as contact metamorphism of such deposits. I personally have used petrology survey boreholes to put put together a rough estimate of 1.3 million sqkm with 12-19,000 sqkm producing an estimated 1000 Gt CO2 (Henrik H. Svensen) over a period of roughly 500,000 years which led up to the P-T extinction event. There is some dispute over an eruption hiatus shortly after the extinction period which according to Burgess and Bowring's 2015 data chart may have lasted for roughly 500,000 years, but there is still evidence of intrusive magmatism during this time. Regardless, I just love to use this data to point out that during the event, Gt CO2/year production would have been .068 over the 1 million year-long eruption, but today its around 37.5 (2022 data). So .068 Gt CO2/year * 500,000 year = mass extinction. What does 37.5 Gt CO2/year * x year = ?

[@alexdenommee3219]

Siberian Traps, The basalt eruption/large igneous province that occurred also burnt life already present, so your measurements of just the off gassing of lava and various gas chambers wouldn't be including all the organic material that would be absolutely incinerated alongside creating even more gasses. I am CERTAINLY not as smart or knowledgeable as you, but I do know large igneous provinces were absolute behemoths which actually helped shape large land masses, etc.

[@nathanedwards6578]

Unfortunately because we do not have a way of knowing the amount of organic material that previously existed in the area, so we cannot safely apply the information to our calculations. What we can do, however, is understand that it is possible for new and more data to become available (specifically dC13 data as it is the carbon isotope that represents plant life the greatest) to use in the future. For example, if I were to take all the dC13 data for the 1 million year eruption timeline and only apply it to the 500,000 years leading up to the eruption, the result would still only be .136 Gt CO2/year, which would be a disingenuous figure. Hopefully more samples and testing in the future will lead to more exact numbers, but until then I would like the estimates to reflect the data as clearly as possible without adding speculation.

Simon and the writer pump out like 5 or 6 episodes a day spread across all their channels.

They decided to go for the adrevenue dollar over the intellectual respect which you can't really blame them for. Simon used to present these scripts very differently not even that long ago. These channels went from educational entertainment to entertainment with some educational basis.

0:10 Well we really don't have a good way to redirect them either so I'd be careful about giving dinosaurs shit for that. We are kind of on the cusp of being able to do it though and we have even done some practical testing. Right now, we MIGHT be able to redirect an asteroid but it depends on the size and the amount of warning we get. If something the size of the Chixulub impactor appeared tomorrow and was going to hit us within a few months, we'd be pretty fucked too. Also one possible correction. The Permian-Triassic extinction event in where the Siberian Traps spilled a crazy amount of material, that MAY have been ultimately caused by an asteroid too. The Siberian Traps are the antipode of a massive impact crater in Australia that we think may have triggered the Traps. I don't believe it is the scientific consensus though at this point.

It's still a hypothesis that the Deccan Traps had a part to play in the extinction of the dinosaurs. It's hypothesized that the Chicxulub impact exacerbated the ongoing volcanism occurring at approximately it's antidote

[@julianaylor4351]

There is also now fossil evidence to indicate that the impact happened in late Spring and it is also suspected that the object, may have split in two. There is a evidence of a crater in Africa, of a similar age.

Simon's last sentence exposes the sarcasm in his opening (in case it wasn't obvious). Dinosaurs may have had small and smooth brains, but they were around for about 180 million years... which is almost three times as long as it's been since their extinction. Meanwhile, humans have put themselves on the brink of extinction after only 300,000 years... or, if we want to be charitable, still less than 3 million years since homo habilis (the first human ancestor to engage in widespread tool-making). Intelligence is fatal... but we're at the point where our attempts to dumb ourselves down will only accelerate our demise, since our overdeveloped brains have become essential to our survival.

[@ThatWriterKevin]

While I appreciate the deep analysis, Simon's last sentence was just because I thought it would be mildly funny

Fort the record, CO2 does not cause acid rain or oceans, sulphur does. The amount of CO2 needed to bring pH down from 7 to 6 is _mega collossal_ to continue with the terminology. Only a fraction of that amount in sulphur is needed to do the same thing. Looking at Icelands current effusive eruption, they list 11kt a day for CO2 and 8kt a day for Sulphur. Did I mention yet that sulphur is orders of magnitude better at dropping pH yet? I am agronomist, I know how to make fertilizer solutions, and pH is a big thing for us. Additionally, I have an aquarium in which I deliberately dissolve CO2 through a reactor in order to get the plants to grow better. At full juice, I can bring the pH down from 7.2 to 6.6 using CO2. I can crank it up further, but the off-gassing happens far too quickly for this to be a real option. Remember, the more water moves (waves, currents, tidal motion), the more it off gasses. I can say with confidence, based on my own experiences that bringing down the pH of oceans is virtually impossible with just CO2.
