from that article:
Quote:
In snow covered regions, including the Arctic and the Himalayas, the local radiative forcing due to soot deposition is comparable to that exerted by carbon dioxide added to the atmosphere since preindustrial times

Quote:
“Theoretical calculations suggest that small amounts of soot, 10 to 100 ppb by mass, can decrease the reflectance of snow 1 to 5 percent,” says Hadley

Quote:
Typical field concentrations of black carbon are measured at 10 to 20 ppb, but in places scientists have measured concentrations as high as 500 ppb.


We have many decades worth of coal reserves...
do the math

Basically the only thing that will save us is to quit buying electricity... right now!

also, the products that use electricity in high amounts need to be reduced. I don't think there are many other significant uses of coal or other soot-producing fuels beyond diesel in transportation.

just a note: "residuals" are reusing recycled products
