ONLINE COVER The Tibetan Plateau plays an integral role in the flow of water across Asia, supplying water to more than 10 rivers including the Yangtze River, the Yellow River, and the Ganges River. Since climate change is degrading permafrost on the plateau and causing its glaciers to retreat, putting water supplies of nearby regions at risk, near-term Tibetan Plateau climate forecasts are important for adaptation and mitigation planning. However, previous studies have used uninitialized coupled general circulation models that only account for the response of external radiative forcing to provide near-term climate projections. In this study, Hu et al. analyzed outputs from the decadal climate prediction project (DCPP) of the Coupled Model Inter-comparison Project Phase 6 (CMIP6), finding evidence that summer rainfall over the inland Tibetan Plateau is highly predictable over multi-year timescales. The researchers found that real-time decadal forecasts suggest the inner Tibetan Plateau will become continuously wetter, with an 18% increase in summer precipitation from 2020 to 2027 relative to the average from 1986 to 2005.
