You quite literally just singled out a single variable for discussion while denying doing so.

You quite literally said:
>You don't need to model the reactions of flora fuana to predict this highly chaotic system centuries into the future.

I don't think you pass the touring test. You cannot infer how cloud seeding may be quite literally conceived of as chem trails, or see the similarity between such ideas and perhaps understand how some 100 IQ lay person isn't far off in misinterpreting the two, even when it is directly explained to you.

I love how denial tards invoke relativist we can’t know nuthin for climate change. Climate dynamics are very complex but the simple mechanism of CO2 being a greenhouse gas, us pumping massive amounts into the atmosphere therefore causing rapid warming is a pretty simple concept.
If you have any specific evidence against that please share it

Did you know that exposure to some of the tested cloud seeding chemicals use may cause neurological problems in exposed mammals?

You may say it's not being done FOR that purpose, but, you can see how an informed person may be concerned. You certainly would complain if a company crop dusted your house with Roundup wouldn't you?

If they're all airburst, civilization would be fucked but we'd recover and rebuild. The real problem are the nukes sent to destroy other nukes still in their silos or hardened targets. Those will cause huge amounts of fallout and radioactive ejecta that will take insanely long periods of time to recover from. It will push all life down a completely different evolutionary path.

Define "end".

Will Western civilization end? Most definitely.
Will millions die from radiation? Absolutely.
Will billions die from starvation when the food chain breaks? Without a doubt.

Will humanity go extinct, aka. On the Beach? Probably not. Certain parts of the world - Africa, South America, Indonesia - will continue on like just another day in the Third World.

Will the world crumble? No. Earth has survived a lot worse than nuclear winter. It will keep spinning.

Tl;dr No. But eat your dessert first anyway.

NO! We can't just reduce trees to charcoal and burry the coal! We can't market that as tech! Also the tree huggers would crucify us. We need to use ridiculous amounts of electricity and complex patented chemical processes to suck carbon directly out of the air! But we can't use nuclear power, because the tree huggers would crucify us.

Here's how an actual physicist would do it in standard notation
$\partial_i \left(r_k r_k\right)^{n/2} = \frac{n}{2}\left(r_k r_k\right)^{n/2-1}2r_i = n\left(r_k r_k\right)^{(n-1)/2}\hat{r}_i$

You will end up scaring them with your long derivation with "unabbreviated" notation. That's not a good trade off. Stick in summation symbols instead of using Einstein convention, but you are making the derivation needlessly long. imo.

So let me get this straight . . .

Physicists discovered some cosmic phenomena they couldn't explain so they decided to concoct this idea of a new type of matter that is intangible, pervasive, with all kinds of convenient properties for their observations instead of just modifying existing theories of gravity?

The hubris among physicists is hilarious! This whole field should be purged when dark matter is eventually thrown away.

Wrong. The CMB cannot be local, that was refuted decades ago. Here is a cut-out of a CMB map from Planck around a large galaxy cluster. The electrons in the cluster scatter the CMB photons to higher energy. This boosts the CMB brightness at higher frequencies but leaves a shadow at lower frequencies. If the CMB was local it never would have passed by this distant galaxy cluster, and so there is no way for the cluster to form a shadow. The Sunyaev–Zeldovich effect was predicted and confirmed. The CMB is cannot be local.
