Kan du ge en snabb förklaring, argumentation via länk är så jobbig. Annars kan jag hänvisa till

Om du vill ha lite fakta.
Enligt uppsatsen(artikeln/? så har klimat"vetenskapen" och IPCC jämfört äpplen och päron.
Man har inte tagit hänsyn till att albedot utan atmosfär bara är 0,04 utan man har räknat på en jord med atmosfär (albedo 0,3).
"However, without greenhouse gases, the albedo would not be 0.3, which thus leads to the
255K value. The albedo would actually be 0.04. Therefore a valid comparison is actually found in
the theoretical temperature of the Earth-ensemble without greenhouse gases (GHG’s) and with a
correctly corresponding albedo, to that with greenhouse gases with their corresponding albedo. In
this physically meaningful comparison, the difference in temperature between the theoretical ground
surface, and the observed surface with an atmosphere and GHG’s on top, is only 12K, reducing the
inferred strength of the GHE by almost two-thirds. That is, the average global surface temperature
without GHG’s, calculated using the usual method of the Stefan-Boltzmann Law with conservation
of energy given the known solar input and the surface-specific albedo, results in a value of 276K.
The observed average surface temperature with GHG’s present is actually 288K (15C),
and so the
“greenhouse effect” should actually be thought to only provide 12K worth of additional
temperature, not the 33K which is always incorrectly cited."
