I have not found a word to describe the uncanny light as a result of carbon atoms from the deaths of a living forest, dust and cloud originating in Iberia, drifting across Europe, pulled by unusual storm forces. The continental nature of the disturbance invited me to look at proto indo-european roots to form such a word.
This is what I have found ~
blood cloud/haze / esr nebhis
So, I offer the word esranebulous. One cloud, esranebula.
Ghostlight of the Anthropocene. I hope such a word would not have to be used often.
