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.
