Isn't a volcano a high-temperature combustion? Does that get wrapped in with exhaust levels?

Only 2 isotopes of nitrogen are tracked: N-14 and N-15. There are multiple possible sources of oxides of nitrogen mentioned: forest fires, lightning, soil emissions, car exhaust and power plant emissions.
Since NOx from all possible sources is blended in the atmosphere, and no single nitrogen atom of any mass carries a pedigree, it is mathematically impossible to quantify the amount coming from 5 sources with measurements of only 2 isotopes.

"...it is mathematically impossible to quantify the amount coming from 5 sources with measurements of only 2 isotopes."

True as far as you went, tadchem.

But the larger point is, since the start of the industrial revolution, atmospheric acidity has gone up, and that can be tracked.

It's just one study, one datum, but it confirms many, many other analytical methods.

Industrialization, relying on coal and other hydrocarbons, is changing the troposphere. Rapidly. CO2 is rising by leaps and bounds. The Arctic is warming rapidly, threatening release of massive stores of carbon and reducing the Earth's albedo. Oceans are acidifying. Species are migrating away from the equator. Tropical diseases are migrating to temperate zones, too. A huge extinction event is well underway - one of the six largest since life began, some scientists observe. The evidence is there.

No. Of course not.

Do you think that volcano's burn rock?

Not primarily, but some materials in magmas could well be above their flash point, which would actually cause combustion when they reach the surface and contact oxygen.

The components of magma are typically well-oxidized, but that's beside the point. Both precursors of NOx, oxygen and nitrogen, are in the air itself. They simply require high temperature and/or high pressure, such is occur in a combustion engine or lightning plasma channel, to combine. I'm not certain magma is hot enough to create much, especially since there's not much exposed magma surface area on the planet at any given point and it tends to cool off rapidly.

I need not wonder either. It is because it hasn't peaked.

As CO2 levels continue to increase, so too will the acidity of precipitation and surface water.

You again? Look at the chart, do you understand what a down trend is? Nope, that's right you only understand scare tactics and pseudo-science.

JoeBlueTard is not smart enough to realize that the downward slope shown in the graph is a downward slope in PH, and lower PH levels indicate higher levels of acidity.

PH = -log(J Concentration)

So the acidity hasn't peaked, it has traufed.

Sadly, Idiots like Joe Blue will never have enough brain power to realize that they are idiots.

I wish more of that acid would fall on my little plot of alkaline soil.

Sad how the grain belt of the U.S. is reverting to desert, isn't it ScooTard?

Some people might consider that Justice for the crimes against humanity committed by America.

It figures that you would blame the alkalinity of my soil on mankind, even though you don't even know where I live.

Even sadder that you see fit to lie with every breath.

It is very Conservative of you.

LOL. And then you're down-voted twice. Any chance either of those are NOT from VendicarD and his/her sockpuppets.

To be fair though, Vendicar, you said "some people might consider" and I am one of those folks. I might consider it delayed retribution. I didn't notice you blaming it on mankind.. only the possibly that some might think "serves em' right, damn Americans".
