With GHG's and a GHE, the upper troposphere
cools via radiation.
Not exact matches
As far as I know, if the only physical mechanism under consideration is the radiative
cooling of the planet's surface (which was heated by shortwave solar
radiation and reradiated at longer wavelengths in the infrared)
via radiative transport, additional gas of any kind can only result in a higher equilibrium temperature.
Considering also that Northern Hemispheric
cooling in 1940 — 70 is attributable to the «global dimming» effect of increasing sulfate aerosols, the sulfate
cooling effect is, again, felt more strongly in Greenland, and indirectly
via altered atmospheric dynamics not
via local
radiation budget modification.
Land surfaces
cool primarily
via radiation.
If the upper troposphere
cools only by
radiation (with probably some convection across the tropopause), but the surface transfers energy to the upper troposphere
via radiation, convection, and evapotranspiration, why would the concurrent CO2 - induced warming be uniform?
Understanding how the earth and atmosphere
cool to space
via radiation is a critical component in understanding surface temperature changes.
Ever heard anyone talk about the overall balance between CO2 «back -
radiation» and CO2
cooling via convection?
If heat in a mixture comes from a source in wavelengths not absorbable by CO2, CO2 will not contribute additional warmth, but will
cool via emission of infrared
radiation.
