Uncertainties in Carbon Dioxide Radiative Forcing in Atmospheric General Circulation Models

This is the authors' abstract. We don't add key points for this paper.

Global warming caused by an increase in the concentrations of greenhouse gases, is the direct result of greenhouse gas-induced radiative forcing. When a doubling of atmospheric carbon dioxide is considered, this forcing differed substantially among 15 atmospheric general circulation models. Although there are several potential causes, the largest contributor was the carbon dioxide radiation parameterizations of the models.
