So the big deal with the Diesel[scandal] is that Nox emissions are off the chart. Nox, or Mono-Nitrogen Oxide, is a byproduct of the lean oxygen free combustion process of diesels generally and its pretty bad stuff. It forms smog and ozone and has been linked to health effects from aspiration issues (brochitus, athsma, etc) to mutation...yeah not to mention the formation of Nirtic Acid (i.e. acid rain). BUT, it does have upside

“NOx emissions also causes global cooling through the formation of OH groups that destroy methane molecules, countering the effect of greenhouse gases. The effect can be significant. For instance, according to the OECD “the large NOx emissions from ship traffic lead to significant increases in hydroxyl (OH), which is the major oxidant in the lower atmosphere. Since reaction with OH is a major way of removing methane from the atmosphere, ship emissions decrease methane concentrations. (Reductions in methane lifetimes due to shipping-based NOx emissions vary between 1.5% and 5% in different calculations).” “In summary, most studies so far indicate that ship emissions actually lead to a net global cooling. This net global cooling effect is not being experienced in other transport sectors....”

“However, it should be stressed that the uncertainties with this conclusion are large, in particular for indirect effects, and global temperature is only a first measure of the extent of climate change in any event.” !!!error: Indecipherable SUB-paragraph formatting!!! ”

So all in all, Nox = bad. But it is does have some upsides.

TLDR: The Earth’s climate is extremely complicated and we barely understand how our actions affect the world

sort of? I think you’re not wrong but I was just giving context to what this “Nox” we’re all hearing about is and not really commenting on the greater global climate.

“However, it should be stressed that the uncertainties with this conclusion are large, in particular for indirect effects, and global temperature is only a first measure of the extent of climate change in any event.”

This line violates the Internet “Journalism” code of ethics:

...

Section 612: Anything which lessens hysteria or otherwise allows working hypotheses to be taken as anything other than incontrovertible facts shall not to be published.

Which is why we jump to the seemingly simplest solutions (ridiculous emissions standards for cars while the shipping industry doesn’t have to give a fuck).

TLDR: NOx is mostly bad, but can kind of be good because it counteracts the other bad stuff we put in the air?

Yea, I kind of drew my own conclusion there, but I still stand by it even though it wasn’t the point you were making.

The more you know. I already knew about NOx but wasn’t aware of the possible global cooling effect.

How dare you use facts and science like that. I bid you good day sir
