How Much Modification Can Earth’s Water Cycle Handle?
The planetary boundaries framework defines how much human disturbance various Earth system processes can take, but it may not adequately depict the water cycle or the extent to which we’ve altered it.
An Element of Randomness in Modeling Arctic Ice Cover
Incorporating random variation of temperature, humidity, and wind offers a computationally cheap alternative to improving resolution in an Earth system model when predicting when Arctic sea ice will disappear.
Machine Learning Improves Weather and Climate Models
New research evaluates the performance of generative adversarial networks for stochastic parameterizations.
Why Is Climate More Sensitive in the Latest Earth System Models?
Compared with previous generations, current Earth system models predict that Earth’s climate is more sensitive to carbon dioxide. Where does the increased sensitivity come from?
One Step Closer to a Milestone in Climate Modeling
A pair of revisions to the Energy Exascale Earth System Model improves its ability to capture late afternoon and nocturnal rainfall as well as the timing and movement of convection.
Diagnosing Soil Moisture Impacts on Model Energy Fluxes
Do climate models truthfully mimic how drying soil affects land-surface budget partition?
Role of Humans in Past Hurricane Potential Intensity Is Unclear
In recent decades, there have been more intense North Atlantic hurricanes. A new study compares climate models to see whether they can attribute increasing potential intensity to human activity.
Did a Volcanic Eruption in 1783 Change the Climate in Europe?
A new model of the Laki eruption in Iceland suggests that normal climate variability was to blame for the anomalously warm summer.
A New Road Map for Assessing the Effects of Solar Geoengineering
A special issue dedicated to modeling the impacts of stratospheric sulfur dioxide injections is a crucial step toward understanding the climate goals this intervention can—and cannot—achieve.
