Microbial life forms exist that permanently inhabit and travel through the atmospheric boundary layer
the verdict
CONTESTED
the evidence cuts both ways
confidence 28/100
While diverse microbial life forms are routinely detected traveling through the atmospheric boundary layer, current evidence indicates they are dispersed from surface ecosystems rather than permanently resident or reproducing in the air.
