On the physical chemistry of the greenhouse effect
Abstract
Abstract.A need for physicochemical data on the
greenhouse effect had been identified. So far, the observation-based CO2–T
correlation has not been confirmed by physicochemical results. Results
regardingthe molar heat capacities of the gases in the atmosphere are
discussed. The contribution of CO2 to heat storage in the atmosphere
is negligible. The role of so-called greenhouse gases as transmitters and
converters between the kinetic energy of molecules and photon energy in
radiative equilibrium (specifically within the IR-(Infrared)-region) is
discussed. Balances of CO2 exchange between the atmosphere, the
plant world, and the oceans compared to anthropogenic emissions are critically
assessed. The anthropogenic energy flow is four orders of magnitude smaller
than daily solar radiation. The separation and final
storage of carbon dioxide (CCS) and the conversion of carbon dioxide with
hydrogen into synthetic gas (CCU) are considered from an energy perspective. The “greenhouse atmosphere” of the Earth is an
open system. The radiation balance should be considered as a steady-state
(flow) equilibrium, which should be assessed according to the principles of
Irreversible Thermodynamics.
Key words: Greenhouse
gases, heat capacity, energy transmitters and senders, CO2 exchange,
radiation balance, infrared radiation, energy flows, CCS technology
