About

Kyle Armour is a professor and the director of the Program on Climate Change at the University of Washington. He holds a joint professor position in the School of Oceanography and the Department of Atmospheric and Climate Science. His research focuses on understanding the dynamics of Earth’s climate through the analysis of observations and numerical simulations with both idealized and comprehensive climate models. His work includes studying recent and future sea ice changes, polar oceanography, and global climate change. Recently, he has worked on topics such as the assessment of the reversibility of Arctic sea ice loss, the time-dependence of atmospheric feedbacks, and regional climate predictability.

  The Summary for Policymakers (SPM) of the Synthesis Report (SYR) of the Sixth Assessment Report (AR6) of the Intergovernmental Panel on Climate Change (IPCC), is a component of the SYR which provides a policy-relevant but policy-neutral summary of the SYR. It is consistent with the Sections of the SYR and is approved line by line by the Governments at a plenary session of the Intergovernmental Panel on Climate Change.

• Systematic Climate Model Biases in the Large‐Scale Patterns of Recent Sea‐Surface Temperature and Sea‐Level Pressure Change

  Geophysical Research Letters · 2022 · 289 citations

  Abstract Observed surface temperature trends over recent decades are characterized by (a) intensified warming in the Indo‐Pacific Warm Pool and slight cooling in the eastern equatorial Pacific, consistent with Walker circulation strengthening, and (b) Southern Ocean cooling. In contrast, state‐of‐the‐art coupled climate models generally project enhanced warming in the eastern equatorial Pacific, Walker circulation weakening, and Southern Ocean warming. Here we investigate the ability of 16 clima…

• Intermodel Spread in the Pattern Effect and Its Contribution to Climate Sensitivity in CMIP5 and CMIP6 Models

  Journal of Climate · 2020 · 170 citations

  Abstract Radiative feedbacks depend on the spatial patterns of sea surface temperature (SST) and thus can change over time as SST patterns evolve—the so-called pattern effect. This study investigates intermodel differences in the magnitude of the pattern effect and how these differences contribute to the spread in effective equilibrium climate sensitivity (ECS) within CMIP5 and CMIP6 models. Effective ECS in CMIP5 estimated from 150-yr-long abrupt4×CO2 simulations is on average 10% higher than t…
