BACKGROUND:
PreviousresearchbyKas,ngetal.(1989)provesthatS8,astrongabsorberinthenearultraviolet,couldhaveformedanultravioletshieldintheanoxicatmosphereoftheearlyEarth.
Itislikelythatamorphoussulfur(S3,S4)wouldhavebeenintheatmosphere,too.
Ques%on:CanatmosphericsulfuraerosolswarmthesurfaceoftheearlyEarth,andthussolvethefaintyoungSunparadox?
