Fight Global Warming - Collect More Dust

Although I agree that these dust collecting systems will certainly help reduce particulates, which can cause respiratory problems and worse, and alone validates their adoption, I don't see them reducing Global Warming much. If anything, the reduction in sunlight reflecting dust (which causes global cooling) would offset any gain in efficiency helping to fight Global Warming.

Still, I think if a reduction in particulates can lead to a reduction in the number of cases of asthma, these filters are more than worth it.

It's interesting that California's AG is suing the auto industry for pollution and greenhouse gases and cites reduced snow packs as one of the aggravating factors in the suit's damage claims. There is research that shows that cleaner emissions of the past 30 years have reduced the amount of particulate cloud nuclei that are essential for snowflage crystal growth- so, really the auto industry produced cleaner burning engines like the government demanded but now are being punished for the results of that same government's regulations!

Actually, California is suing the automakers for Global Warming, which is caused by CO₂ emissions. It's true that automakers have improved particulate levels, but there is not a hint of scientific research that I'm aware of that suggests that automotive particulates can cause significant climate change. There is however significant evidence that CO₂ can cause climate change. So to suggest that the reduction in snow packs is because automakers have reduced particulate emmissions, and are being punished for following regulations, while ignoring the CO₂ emmissions of these same cars seems incorrect.
