Charged by thunderstorms and other weather phenomena, the global electrical circuit connects the entire planet.
Global climate models
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?
Evaluating Cloud Cover Predictions in Climate Models
A new analysis highlights progress in predictions of cloud cover from models that are part of the Coupled Model Intercomparison Project.
The Overlooked Role of Sulfur Dioxide Emissions from Volcanoes
Volcanoes can warm as much as they cool. Prior simulations have neglected the important warming effects of sulfur dioxide emissions, making some results colder than they should be.
Emerging Controversy in Madden-Julian Oscillation Prediction
The Quasi-Biennial Oscillation modulates the Madden-Julian Oscillation in observations, but it does not significantly influence prediction skills in a multi-model assessment.
Hackathon Speeds Progress Toward Climate Model Collaboration
Climate scientists collaborated in a nationwide event to analyze and compare archived Earth system model simulations and to generate input for the IPCC’s upcoming climate change report.
Effects of Variability in Atlantic Ocean Circulation
There is strong evidence that the Atlantic meridional overturning circulation plays an essential role in Atlantic multidecadal variability and associated climate impacts.
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.
3D Radiation-Topography Interaction Warms Up Tibetan Plateau
3-D radiation-topography interaction, which can increase the sunlight absorption by the surface, is missing in all climate models, causing strong cold biases over the Tibetan Plateau.
Finding Sources of Uncertainty in the Spatial Pattern of Warming
The planet is heating up, but uncertainty still exists about how temperatures will change in specific regions. A new study examines sources of uncertainty in the meridional pattern of warming.
