Die geheimnisvolle Rolle des „anthropogenen Radiative forcings – was steckt dahinter?
Unter Strahlungsantrieb (radiative forcing) versteht man die Differenz zwischen der einge-henden solaren und der ausgehenden langwelligen Strahlungsintensität. Der IPCC definiert dies etwas anders: „The definition of RF from the TAR and earlier IPCC assessment reports is retained. Ramaswamy et al. (2001) define it as ‘the change in net (down minus up) irradiance (solar plus longwave; in W/m2) at the tropopause after allowing for stratospheric temperatures to readjust to radiative equilibrium, but with surface and tropospheric temperatures and state held fixed at the unperturbed values” (AR4, Ch.2, p.133).
