AbstractIn recent decades, relative humidity over land has declined, driving increases in droughts and wildfires. Previous explanations attribute this trend to insufficient moisture advection from the ocean to sustain the current level, but this ignores atmospheric moisture supplied from terrestrial evapotranspiration. Importantly, current state-of-the-art climate models continue to underestimate the observed relative humidity trend over land.

Abstract The magnitude and extent of runoff reduction, drought intensification, and dryland expansion under climate change are unclear and contentious. A primary reason is disagreement between global circulation models and current potential evaporation (PE) models for the upper limit of evaporation under warming climatic conditions.
