Then Rasool and Schneider in 1971 made THE declaration that like CO2 and could have a huge impact on global climate.

The stage was set.

GISS could no longer be an institute for outward facing space studies…

We had to turn back to earth... ...

Il y a 10 000 ans, il aurait été beaucoup plus difficile pour un de se transmettre entre humains qu'il ne l'est aujourd'hui.... La qualité de l' intérieur est largement définie par la concentration de contaminants qu'il contient. Plus la concentration de contaminants est élevée, plus la qualité de l'air est mauvaise. Divers contaminants atmosphériques peuvent nuire à la santé. seenthis.net/messages/1013168

In terms the levels of loading are quite high (shown here the Aerosol Optical depth at NASA GSFC in Maryland).

Anything above 0.4 (500 nm channel) is considered polluted and we are 4 times that level.

Fortunately most of the smoke is rather elevated and not near the ground (for now). Profile of distribution from a lidar in UMBC, note the lower concentrations near the surface in the last few hours.

The paradox of atmospheric cooling is that it could make global warming worse. Atmospheric cooling is caused by aerosols, tiny particles that reflect sunlight and reduce the greenhouse effect. However, aerosols also negatively impact human health, crop yields, and rainfall patterns. Moreover, if aerosol emissions are reduced, the cooling effect will disappear and the full force of global warming will be felt.

Is it that hasn't been profitable for any of the big corporations?

I don't understand how anybody would think that spraying anything the air to eliminate certain is a good idea. Certainly not for a that's like .

I mean how often is hoping that we use its spray which "helps reduce the spread of airborne pathogens such as cold, Influenza and Coronavirus" (in linked Reuters article)?

Ar6-workgroup1 has a section on or what people call .
There's a chart showing world regions and their respective amount and their evolution of aerosol-induced cooling. The most cooling came from Europe, US is 2nd. Both have long ago enacted clean-air acts to fight acid rain. There's not much left in the pipeline from the other regions.
But the cooling from Europe's and North Anerica's air pollution also drove Africa's rain band south which caused droughts and famines and genocides in the 80s...That geoengineered change has been reversed by now, but it took decades - and we didn't even know until recently that we were responsible for what happened in Africa.

It's a really good chart, I think. Have a look on the IPCC website.
It's Figure 6.15 here ipcc.ch/report/ar6/wg1/figures
It helps to read the section in chapter 6, too.

Wildfire smoke affected events around world
The new study also showed how the in the wildfire smoke affected another important piece of the climate system, the Intertropical Convergence Zone. The zone is often visible in images as a nearly unbroken line of clouds extending across the oceans. It’s important because its position determines where falls and which areas are dry.

…fading. I hope the lessons learned never do.

Today, right now, is the only present. You woke up this morning with the shitty present circumstances of whatever got you infected with this . Maybe the former version of you that went somewhere and inhaled those would have listened if current you had stepped in front of the door and said, “Don’t go in there.” Maybe not. But it doesn’t matter, because the whole event is gone, and all that exists is what’s happening now. 3/
