Carbon dioxide warming of the early Earth

摘要: Svante Arrhenius' research in atmospheric physics extended beyond the recent past and near future states of Earth, which today are at center sociopolitical attention. His plan encompassed all physical phenomena known time to relate formation evolution stars planets. two-volume textbook on cosmic is a comprehensive synopsis field. The inquiry into possible cause ice ages theory selective wavelength filter control led Arrhenius consider surface other terrestrial planets, ancient Earth before it had been modified by emergence life. rapid escape hydrogen equilibration with igneous rocks required that carbon early atmosphere prevailed mainly oxidized form as dioxide, together photoactive gases exerting greenhouse effect orders magnitude larger than our present atmosphere. This effect, ensuing chemical processes, would have set conditions for life evolve planet, seeded from spores spreading through an infinite Universe, propelled, thought, stellar radiation pressure.
