GCAM v5.1: Representing the Linkages between Energy, Water, Land, Climate, and Economic Systems
Evaluating the Future Evolution of Virtual Water Trade
PNNL researchers combined future socioeconomic and climate conditions in a complex model that accounts for the relationships between energy, water, land, climate, and human activities to predict future changes in virtual water trading.
Projecting the Future Trade of Virtual Water
An analysis led by PNNL scientists projects that the volume of virtual water embedded in the global agriculture trade could triple by 2100. The results point to regions that might become global food suppliers or dependent on food imports.
How Have Local Radiative Feedbacks Contributed to Polar Amplification since 1980?
PNNL scientists led a study to quantify radiative feedbacks using historical short-term climate simulations. These simulations can reproduce the observed warming and polar amplification.
Global Methane Emissions From Coal Mining To Continue Growing Even With Declining Production
New analysis indicates that emissions from abandoned mines will contribute to higher emissions than previously thought.
Sensitivity of Sea Ice Albedo Feedback Estimates to the Calculation of Atmospheric Transmissivity
A new procedure for estimating sunlight reflection provides insight into feedbacks that affect Arctic warming.
Digging Into Uncertainty in Energy Consumption Data
As countries revised previously reported statistics, coal data showed larger adjustments than oil and natural gas.
Quantifying Uncertainty in the Energy Exascale Earth System Model
A unique strategy sharpens understanding of the behavior and physics within the model’s atmospheric component.
