(2015) strove to determine whether the hydro-climatic conditions that occurred during the 2012-2015 (hereafter current) California-Nevada drought were “within the range of natural variability documented by paleo-proxy indicators,” which they hoped could lead to the “disentanglement of the relative roles of natural versus anthropogenic forcing factors as causative agents.” So what did they do? And what did they learn?
