A new study shows that future ecosystem functioning will increasingly depend on water availability. Using recent simulations from climate models, an international team of scientists found several “hot spot regions” where increasing water limitation strongly affects ecosystems. These include Central Europe, the Amazon, and western Russia. Pinpointing such regions is essential: Healthy ecosystems are vital for society, as they provide several key services, such as food and water security, the uptake of atmospheric carbon dioxide emitted by human activities, and evaporative cooling.

Climate change introduces changes in energy and water availability for plants. Whereas energy availability is consistently increasing …
