Excerpt: ...In a new study, Hsu et al. quantify how global warming affects soil moisture. Although climate change will dehydrate soil, they found, it is not clear how dry is too dry. ...the models disagreed on the threshold at which Earth would become a more moisture-limited system—a value called critical soil moisture. ...Critical soil moisture has wide-ranging impacts on the water cycle, climate, ecosystems, and society. Getting a solid grasp on that value would improve climate models and paint a fuller picture of Earth’s future. (Earth’s Future, https://doi.org/10.1029/2023EF003511, 2023)....
