A new study quantifies persistent phosphorus in a drainage basin in Sweden and points out risks and oversights to factor in to future stream management.
Modeling
Rainwater Harvesting Can Reduce Flooding as Well as Saving Water
Weather forecasting can greatly improve benefits of rainwater harvesting.
Regional Sensitivities Strongly Affect Modeled Climate Extremes
Analysis of temperature and precipitation extremes in two generations of CMIP climate models revealed similarities in regional climate sensitivities, contrasting with divergent global sensitivities.
Environmental Impact Bonds Incentivize Watershed Restoration
Environmental Impact Bonds for financing new water and environmental infrastructure can be properly priced with the help of watershed modelling.
Ensemble Modeling of Coronal Mass Ejection Arrival at 1 AU
Heliospheric imaging data can be used in ensemble modeling of CME arrival time at Earth to improve space weather forecasts, treating the solar wind as a 1-D incompressible hydrodynamic flow.
Improving Proxy Representations of Ocean Properties
Many oceanic properties are not directly observed but are instead estimated using proxy measurements. A new method uses physics-based correlations to reduce uncertainty in this relationship.
Deep-Ocean Oxygen May Increase with Climate Change
A millennial-scale ocean simulation indicates that oxygen gains in the deep ocean may offset oxygen losses in the upper water layer under a protracted climate change scenario.
Dams Alter Nutrient Flows to Coasts
New models indicate how dams worldwide influence the mix of nutrients in river water reaching the ocean. As more dams are built, changing nutrient loads may adversely affect coastal ecosystems.
New Tool Quantifies and Predicts Snow Droughts
A new metric for calculating snow water equivalence relies on three methodologies: modeling, satellite imagery, and direct observation.
Characteristics of Polar Sea Ice in Latest Climate Models
Sea ice area in CMIP6 is similar to previous versions while its sensitivity to external forcing is subtly different and closer to observations, but still not in step with global surface temperature.
