 Climate models predict that global average humidity will increase by approximately 7%, which is consistent with the Clausius-Glaparin, C.C. equation. However, these models also predict that global precipitation and evaporation rates will increase by only about 2%. This suggests that the models may not accurately capture the full extent of the effects of increased humidity on climate. This article was authored by M. L. Roderick, F. Sun, W. H. Lim, and others.
