Ronald J. Stouffer is a meteorologist and adjunct professor at the University of Arizona,[1] formerly Senior Research Climatologist and head of the Climate and Ecosystems Group at the Geophysical Fluid Dynamics Laboratory (GFDL), part of NOAA.

[4] With 2021 Nobel laureate Syukuro Manabe, Stouffer developed the first models to couple the atmosphere and ocean to create global climate warming projections.

[6][7] He has published at least 220 papers on climate change,[8] and has been recognized as a Highly Cited Researcher by Clarivate Analytics for multiple years.

[1] Stouffer collaborated with Syukuro Manabe, who created the first climate models to show the effects of carbon dioxide building up in the atmosphere.

[13][14] This research raised concerns about the stability of the Atlantic meridional overturning circulation (AMOC) and its potential to change abruptly and to dramatically impact climate.

[16]: 596 As early as 1988 Manabe and Stouffer's models showed pronounced impacts on tropical rainfall, but the significance of that feature of the simulations was not focused on at the time.

[22] To write the IPCC reports, over 250 scientists and experts worldwide evaluate, synthesize, and comment on the published literature about climate change, summarizing the state of what is known from peer-reviewed studies.

The IPCC reports clearly describe the scientific consensus that climate change is real, that it is caused by human activity, and that it urgently needs addressing.
