This post is prompted by an article published by Richard Seager et al. at AMS Journal Is There a Role for Human-Induced Climate Change in the Precipitation Decline that Drove the California Drought? Excerpts in italics with my bolds.
The recent California drought was associated with a persistent ridge at the west coast of North America that has been associated with, in part, forcing from warm SST anomalies in the tropical west Pacific. Here it is considered whether there is a role for human-induced climate change in favoring such a west coast ridge. The models from phase 5 of the Coupled Model Intercomparison Project do not support such a case either in terms of a shift in the mean circulation or in variance that would favor increased intensity or frequency of ridges. The models also do not support shifts toward a drier mean climate or more frequent or…
