After undergoing five years of drought, many Californians may fear a future with less rainfall thanks to climate change. However, research carried out at the University of California, Riverside, suggests precipitation across the state may actually increase over the next hundred years. The paper, published in the journal Nature Communications, looked at several different California climate models and aggregated the results. However, not every model is good at predicting factors like precipitation. So, rather than simply aggregating the findings, Robert Allen, a climatologist at the University of California, Riverside, and the lead author on the paper, was picky.
