In a now defunct periodical, Speculations in Science & Technology (Vol. 21, #1, March 1998, at page 58), I consciously coined a word [or, more accurately, a short phrase]: the "green-glass effect". It's a play on the technical term "greenhouse effect". After the first nuclear weapon exploded in New Mexico, USA, fused sand was found which was greenish in color (trinitite). I reasoned in 1998 that after a global nuclear exchange (WW III), there might be many such circular regions of fused materials (perhaps 50,000)! And, after the atmospheric dust cleared, a chilled atmosphere would be warmed more quickly if the albedoes of these spots on the pulverized landscape were dark (green instead of conrete white).
