Does this impact Alaska and Canada more than Russia?
It’s going to cast a cloud over a long portion of the pacific for sure. Hello global cooling!!🥶
Quick answer yes. But I’d expect it will also hugely impact non-stop flights to and from eastern and midwest cities to Eastern Asia (Japan, Korea, China). All those flights skirt the Kamchatka Peninsula.
Check out the Pacific winds map at Comment #14. Winds frequently blow west to east, so being at the far west end of Russia, most dust should flow to Alaska and Canada.
Depends on which way the wind is blowing I guess.
