The surface air temperature response to vegetation changes has been studied for the extreme
case of land-cover change 1 , 2 , 3 , 4 , 5 ; yet, it has never been quantified for the slow but …

Partitioning global land evapotranspiration using CMIP5 models constrained by observations

X Lian, S Piao, C Huntingford, Y Li, Z Zeng… - Nature Climate …, 2018 - nature.com
The ratio of plant transpiration to total terrestrial evapotranspiration (T/ET) captures the role
of vegetation in surface–atmosphere interactions. However, its magnitude remains highly …

Global water availability boosted by vegetation-driven changes in atmospheric moisture transport

J Cui, X Lian, C Huntingford, L Gimeno, T Wang… - Nature …, 2022 - nature.com
Surface-water availability, defined as precipitation minus evapotranspiration, can be
affected by changes in vegetation. These impacts can be local, due to the modification of …

Summer soil drying exacerbated by earlier spring greening of northern vegetation

X Lian, S Piao, LZX Li, Y Li, C Huntingford, P Ciais… - Science …, 2020 - science.org
Earlier vegetation greening under climate change raises evapotranspiration and thus lowers
spring soil moisture, yet the extent and magnitude of this water deficit persistence into the …
