“…Mainly because of the large PET increase associated with rising SAT, a drier climate is projected for a substantial portion of drylands [e.g., Dai , , ; Hughes , ; Cook et al ., ; Scheff and Frierson , ; Huang et al ., ; Fu and Mao , ] and dryland expansion by 2100 is expected [ Feng and Fu , ; Fu et al ., ; Huang et al ., ]. These changes in temperature, precipitation, and PET may alter terrestrial ecosystems [ Osmond et al ., ; Kullman , ; Zeng and Yoon , ; Badreldin and Goossens , ; Sylla et al ., ; Yu et al ., ; Klein et al ., ; Seddon et al ., ; Sjögersten and Wookey , ; Wu et al ., ], hydrology [ Ohmura and Wild , ; Cudennec et al ., ; Angeler et al ., ; Hu et al ., ], and agricultural production [ El‐Beltagy and Madkour , ; Valizadeh et al ., ; Hadgu et al ., ] over drylands. Because of the drastic climate change and fragile ecosystems of drylands, a better understanding of dryland climate change and its impact is required for further research and policy making.…”
