Projected precipitation volatility under climate change scenarios in western U.S. Basins. (a) This panel illustrates the 40-year moving coefficient of variation for basin-wide precipitation in the California Basin, spanning from 1980–2020 to 2060–2100, under four climate scenarios: CMIP5 RCP 4.5, RCP 8.5, CMIP 6 SSP 2-4.5, and SSP 5-8.5. Solid lines depict the mean values of all models for each scenario, with shaded areas representing 95% confidence intervals. Each point on these lines represents the coefficient calculated over a 40-year window (e.g., the 2020 point shows the coefficient for 1981–2020). Trends for the Near Future (slope between 1981–2020 and 2021–2060) and Far Future (slope between 2021–2060 and 2061–2100) are plotted in terms of annual rate change in the coefficient of variation, with symbols denoting statistical significance ): ns (not significant, p > 0.05), * (p ≤ 0.05), ** (p ≤ 0.01), *** (p ≤ 0.001), and **** (p ≤ 0.0001). (b–d, As in panel (a) but for (b) the Colorado River Basin, (c) the Columbia River Basin, and (d) the Great Basin.
