Vegetation resistance to compound drought and heatwave events buffers the spatial shift velocities of vegetation vulnerability

open access: yesCommunications Earth & Environment
Global warming is increasing compound drought and heatwave events. This elevates vegetation loss probability. Despite spatial shifts in vegetation loss probability being crucial for predicting spatial redistribution patterns of vegetation vulnerability ...

Estimation of glacier ice storage in western China constrained by field ground-penetrating Radar surveys

open access: yesAdvances in Climate Change Research, 2022
Recent decades have witnessed the accelerated retreat of alpine glaciers, which likely portends a decline in the glacial ice melt on which large downstream populations rely for freshwater. Thus, estimating water storage in alpine glaciers is critical for

Upward Expansion of Supra-Glacial Debris Cover in the Hunza Valley, Karakoram, During 1990 ∼ 2019

open access: yesFrontiers in Earth Science, 2020
Supra-glacial debris cover is key to glacier ablation through increasing (thin debris layer) or decreasing (thick debris layer) melt rates, thereby regulating the mass balance of a glacier and its meltwater runoff.
