Earth System Model Simulates a Raised Coastal Groundwater Table Caused by Sea-Level Rise
Seawater threatens to intrude into coastal freshwater aquifers that millions of people depend on for drinking water and irrigation. This study investigates sea-level rise impacts on the global coastal groundwater table.
From Factories to Flurries, Industrial Particles Are Spurring Downstream Snowfall
A recent paper published in Science sheds light on how aerosols—tiny particles in the air—released by industrial activities can trigger downstream snowfall events.
Molecular Observation Network
The Molecular Observation Network is a national open science network designed to produce a comprehensive database of molecular and microstructural information on soil, water, microbial communities, and biogenic emissions.
Modeling a Control Strategy to Reverse Sea-Ice Loss Near its Tipping Point
Several Earth system components are at a high risk of undergoing rapid, irreversible qualitative changes or ‘tipping’ with increasing climate warming.
Bighorn Sheep Face Death by Avalanche in Sierra Nevada Range
Knowing future snow levels is key for managing the recovery of endangered bighorn sheep. PNNL scientists help to forecast how the sheep could fare.
Delay and Pay: Tipping Point Costs Quadruple After Waiting
A new study reveals just how costly Earth's tipping points can be.
The Complexity of Amplified Arctic Warming can be Understood Analytically
The results of this study reveal that the degree of Arctic amplification, despite being controlled by complicated interactions among multiple factors, can be analytically understood.
Future Climate Change Predicted to Shift Flood-Generating Mechanisms and Intensify Extreme Flooding Events
The Delaware River Basin is projected to experience a regional increase in flood severity under future climate scenarios.
Interpretable and Physics-Aware Neural Networks Improve Modeling of Turbulence Near the Surface
A new study uses direct numerical simulations to develop a near-surface turbulence model for thermal convection using interpretable and physics-aware neural networks, broadening the applications of numerical simulations.
