Dust on Ice Sheets = End of Glaciation

I’m still working my way through this but:

“The role of dust in terminations of Ice Ages is probably far more important than many realize. It appears likely that unusually high dust levels coupled to sharply rising solar intensity at high latitudes was a major factor in initiating termination of Ice Ages. As Palmer put it, layers of buried dust probably sustained the evolution of the interglacial period.”

Dust deposition on ice sheets: a mechanism for termination of ice ages?

And if that is true, what about the dust at the end of the 1920s leading to the big temperature increase in the 1930s. Or the soot from the massive expansion of coal burning power plants and diesel cars/trucks?
