Polar Amplification Model Intercomparison Project

Polar amplification, the phenomenon that external radiative forcing produces a larger change in surface temperature at high latitudes than the global average, is a key aspect of anthropogenic climate change but its causes and consequences are not fully understood.

The Polar Amplification Model Intercomparison Project (PAMIP), co-led by Dr. Doug Smith, Dr. James Screen, and Dr. Clara Deser seeks to improve our understanding of this phenomenon through a coordinated set of numerical model experiments. As one of the Coupled Model Intercomparison Project Phase 6 (CMIP6) endorsed MIPs, PAMIP will address the following primary questions:

  1. What are the relative roles of local sea ice and remote sea surface temperature changes in driving polar amplification?
  2. How does the global climate system respond to changes in Arctic and Antarctic sea ice?
