  • Climate change is expected to intensify the global hydrological cycle and to alter evapotranspiration, but direct observational constraints are lacking at the global scale. Now a data-driven, machine-learning technique and a suite of process-based models have been used to show that from 1982 to 1997 global evapotranspiration increased by about 7.1 millimetres per year per decade. But since 1998 this increase has ceased, probably because of moisture limitation in the Southern Hemisphere.

  • The darker surfaces of water reservoirs absorb more sunlight than ground surfaces, yet how much this reduces the climate benefit of hydroelectricity has not been investigated. Now, Wohlfahrt et al. demonstrate that this albedo penalty may be considerable for certain hydropower reservoirs.

  • The albedo-induced warming effect with increased net ecosystem productivity can be overcome by optimizing albedo and land carbon uptake, according to an analysis of in-situ observations from 176 eddy covariance flux stations across different ecosystem types and conditions.
