Short summary
As the climate warms, drier air can change how water moves from land to the atmosphere. We used global satellite and climate data from 1981 to 2020 to study this change. We found that drier air was linked to greater water loss over about 61% of land, especially in warm and humid regions. Plant water loss was more strongly linked to air dryness than water loss from bare soil, while dry regions showed limits or declines. These results can improve forecasts of future water-cycle change.
