Abstract Using the Coupled Model Intercomparison Project Phase 5 (CMIP5) simulation of air temperature, precipitation and extreme events change under Representative Concentration Pathways(RCPs) scenario, we carried on a forecast of climate change in the Qinghai Plateau in the 21st century.The results show a significant rise of annual average air temperature in the Qinghai Plateau in the 21st century, warming rates will be 0.06 ℃/10a, 0.24 ℃/10a and 0.61 ℃/10a respectively in RCP2.6, RCP4.5 and RCP8.5 emissions scenarios. Annual precipitation will increase obviously, range between 1.4-7.0 mm/10a. In the 21st century the precipitation and temperature will become more extreme, there would be an overall increasing trend in extreme air precipitation and temperature events over most of the Qinghai Plateau under a warming environment, and the change scope is scaled to the emissions scenarios.
