Abstract
This study investigated the projected changes in the annual mean surface air temperature (SAT) over China under the 1.5 and 2.0 °C targets, by analyzing the outputs from 22 models of the Coupled Model Intercomparison Project Phase 5. Under the 1.5 °C target, the scope of changes in the average SAT over China is quite narrow and has the largest probability to increase by 1.7-2.0 °C under the various RCP pathways, although the time of occurrence of the 1.5 °C target has a large spread of 40-60 years. Similarly, the models consistently show that the average SAT over China would most likely increase by 2.4-2.7 °C under the 2.0 °C target. Furthermore, the warming shows a clear spatial distinction over China: being stronger in the northwest part and weaker in the southeast part. Under all RCP pathways, the SAT over the northwest part would increase by 1.9-2.1 °C for the 1.5 °C target, which is much stronger than the SAT increase over the southeast part (1.3-1.5 °C). A similar spatial pattern appears for the 2.0 °C target.
