Some recent studies have revealed a significant concentration of particles in near-surface waters in areas of mid-ocean accumulation (N Pacific and NW Atlantic gyres).
Arrhenius predicted that if the carbon dioxide concentration increased, the mean temperature of the surface of the earth would increase, in pretty much the way he said it would.
Since then, the concentration of carbon dioxide has in fact increased and the mean temperature of the surface of the earth has increased in pretty much the way Dr. Arrhenius said it would.
