Too many climate researchers are making unrealistically dire projections about the future consequences of man-made climate change based on computer models that run way too hot, argues a new commentary in Nature.
The commentary's authors point out that the too-hot models reported in the sixth phase of the Coupled Model Intercomparison Project (CMIP6) failed to reproduce historical climate trends, thus casting considerable doubt on their more catastrophic temperature increase projections. Consequently, the researchers note that the former practice of "simply taking an average" of all of the models together leads to higher projections of warming than is warranted.
