Abstract: n analysis of the October 2013?September 2014 precipitation in the western United States and in particular over the California?Nevada region suggests this anomalously dry season, while extreme, is not unprecedented in ...

Abstract: merdon et al. report two errors in the climate model grid data used in previous pseudoproxy-based climate reconstruction experiments that do not impact the main conclusions of those works. The errors did not occur in ...

Abstract: Two widely used statistical approaches to reconstructing past climate histories from climate ?proxy? data such as tree rings, corals, and ice cores are investigated using synthetic ?pseudoproxy? data derived from a simulation ...

Abstract: AbstractThe recent dryness in California was unprecedented in the instrumental record. This article employs spatially explicit precipitation reconstructions for California in combination with instrumental data to provide ...

Abstract: In a recent paper, Christiansen et al. compared climate reconstruction methods using surrogate ensembles from a coupled general circulation model and pseudoproxies. Their results using the regularized expectation maximization ...

Abstract: Year-to-year extreme alterations in California (CA) precipitation, denoted here as flips, present significant challenges to resource managers, emergency management officials, and the state’s economy and ecosystems generally. ...

Abstract: n overview of a simulation referred to as the ?Last Millennium? (LM) simulation of the Community Climate System Model, version 4 (CCSM4), is presented. The CCSM4 LM simulation reproduces many large-scale climate patterns ...
