The Sichuan–Tibet Railway is the most challenging, undergoing railway project in human history. “President Xi Jinping said that construction of the project will face rarely seen difficulties because of geological conditions, the complex climate along the railway and the fragile environment” (China Daily, http://www.chinadaily.com.cn/a/202103/10/). Zhang et al. (2021, this issue of JMR) reported that the temperature (precipitation) along this rail line has shown a warming (decreasing) trend in the past 40 years. They predicted that the trends will continue, with increased number and frequency of extreme climate events in the future.
