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.

International Collaboration Yields Unique Climate Simulations

by P. Caldwell 29 January 202125 January 2021

Porting and optimizing CESM1.3 to run on the TaihuLight computer enabled an astounding 750 years of simulation with 0.25° grid spacing for land & atmosphere and 0.1° grid spacing for ocean & sea ice.

The Perils of Computing Too Much and Thinking Too Little

by B. Stevens 25 June 2020

Big steps forward are synonymous with new ideas – a thought that merits mindfulness if we aspire to train students to do more than merely train machines.

Tracking Tropospheric Ozone Since 1979

by David Shultz 19 May 202026 October 2021

Stratospheric ozone depletion between 1979 and 2010 resulted in a slight decrease of ozone in the troposphere during that period despite increased ozone production from anthropogenic emissions.
