A new paper in Environmental Research Letters reveals how recent land-cover shifts across the Arctic–Boreal region are already cooling daily high-temperature extremes yet intensifying multi-day drought risk—insights gained by driving CESM2 with 30 m satellite maps.
The study, led by Shuai Li with Di Yang and colleagues, quantifies albedo-driven changes of up to 0.6 °C in TXx and a three-day rise in consecutive dry days, underscoring land management’s leverage over polar-climate resilience
