Today's complex climate models aren't equivalent to reality | Aeon Essays

Earth System Models diverge substantially from reality, especially at regional and local scales, limiting reliable detailed local climate predictions.

Uncertain climate effects of anthropogenic reactive nitrogen - Nature

The net climate effect of anthropogenic reactive nitrogen (Nr) is the sum of several terms that vary in sign and are associated with substantial uncertainties. Gong et al.1 reported a net negative direct radiative forcing (RF) of Nr in the year 2019 relative to the year 1850. We argue that their estimates and associated uncertainties of individual Nr climate effects, most notably aerosol, ozone and methane RF, do not reflect the current state of the art.
