Since the 2015 Paris Agreement, 1.5 and 2 C warming targets have gradually become a consensus that should be observed and supported by governments and the public all over the world. Global climate change and its impact on socioeconomic development, environment, and our everyday lives under those warming conditions have been thoroughly addressed by voluminous literature (Guiot and Cramer, 2015; van Hooidonk et al., 2016; James et al., 2017; Kraaijenbrink et al., 2017; Huang et al., 2017a). However, most scholars focus on regional mean temperature change, sea level rise, Arctic sea ice melting, and many other slow change processes (Serreze and Stroeve, 2015; Schleussner et al., 2016; Chen et al., 2017; Oliva et al., 2017). In the meanwhile, rapid processes such as extreme high-or lowtemperature events, storms, typhoons, and some other meteorological disasters should not be neglected (Guo et al., 2016; Nangombe et al., 2018). Some scholars have made great contributions to analysing extreme climate change in certain specified global warming targets. Note that most previous studies concentrated on the spatiotemporal changes of major climate extremes themselves (eg, heatwaves and floods). For instance, larger anomalies in climate extreme
