Description:
Extreme high-temperature events have large socioeconomic and human health impacts. East Asia is a populous region, and it is crucial to assess the changes in extreme high-temperature events in this region under different climate change scenarios. The Community Earth System Model low-warming experiment data were applied to investigate the changes in the mean and extreme high temperatures in East Asia under 1.5°C and 2°C warming conditions above pre-industrial levels. The results show that the magnitude of warming in East Asia is approximately 0.2°C higher than the global mean. Most populous subregions, including eastern China, the Korean Peninsula and Japan, will see more intense, more frequent and longer lasting extreme temperature events under 1.5°C and 2°C warming. The 0.5°C lower warming will help avoid 35%-46% of the increases in extreme high-temperature events in terms of intensity, frequency and duration in East Asia with maximal avoidance values (37%-49%) occurring in Mongolia. Thus, it is beneficial for East Asia to limit the warming target to 1.5°C rather than 2°C.
