Ice Age Testing Reveals Challenges in Climate Model Sensitivity

by Morgan Rehnberg 2 March 202126 October 2021

Increased reflection of incoming sunlight by clouds led one current-generation climate model to predict unrealistically cold temperatures during the last ice age.

New Insights into Uncertainties About Earth’s Rising Temperature

by Sarah Stanley 30 October 2020

A comparison of climate models finds that much of the variation in their predictions of global warming arises from differences in how they simulate the response of convective processes to warming.

A Global View of Shapes and Sizes of Ice Crystals in Cloud Tops

by Z. Li 9 July 202027 June 2020

Ice particles have systematic covariations and temperature dependences that are surprisingly consistent with a simple ice growth theory as revealed by satellites.

Pushing the Computational Limits of Climate Simulation

by Sarah Stanley 17 March 202029 September 2021

Researchers apply a superparameterization technique to boost the accuracy and efficiency of climate predictions generated by the Energy Exascale Earth System Model.

A “Super” Solution for Modeling Clouds

by Aaron Sidder 6 September 2019

Climate models struggle to accurately portray clouds because the models cannot resolve the scales at which clouds form. A new study demonstrates a potential fix for the problem.

Improving Estimates of Long-Term Climate Sensitivity

by Terri Cook 5 March 2019

New modeling casts doubt on the suitability of running experiments with fixed sea surface temperatures to understand the effects of cloud aggregation on Earth’s climate.

Finding Sources of Uncertainty in the Spatial Pattern of Warming

by David Shultz 30 January 2019

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.

Diagnosing the Warm Bias in the Central United States

by A. Steiner 23 April 2018

A set of four papers published in JGR: Atmospheres present results from a project investigating why models predict warmer surface temperatures than are observed in the central United States.

How Do Clouds React to Regional Warming?

by S. Witman 12 October 2017

Researchers illuminate how and why cloud feedbacks depend on spatial patterns of global warming.
