New analysis shows the U.S. has accounted for more wetland conversion and degradation than any other country. Its findings help better explain the causes and impacts of such losses and inform protection and restoration of wetlands.
Analysis finds that dammed reservoirs could store more than 50% of the water needed to irrigate crops without depleting water stocks or encroaching on nature. The researchers caution against building new dams, however, and urge consideration of alternative storage solutions.
American beaver populations are booming in the western United States as conditions grow hotter and drier. New research shows their prolific dam building benefits river water quality so much, it outweighs the damaging influence of climate-driven droughts.
Based on new analyses of satellite data, scientists have found that hydrologic conditions that increase flash drought risk occur more often than current models predict. The research also shows that incorporating how plants change soil structures can improve Earth system models.
Across Antarctica, some parts of the base of the ice sheet are frozen, while others are thawed. Scientists show that if some currently frozen areas were also to thaw, it could increase ice loss from glaciers that are not currently major sea-level contributors.
Analysis reveals how restoring relatively narrow forest buffers could substantially improve regional water quality and carbon storage in Costa Rica and elsewhere. Such changes could have outsized benefits for vulnerable populations that rely on rivers for their water supply.
