Abstrac t:

As Earth system models grow in complexity and computat ional cost\, two approaches offer opportunities to accelerate progress and deepen understanding: parameterizations and emulators. I will distinguish these two strategies in a practical way. Ā Focusing on the ocean\, Iā€™ll discuss an emulator that is a key path to quantifying regional mixed laye r depth (MLD) affects climate sensitivity\, connecting surface mixing proc esses to the spread in model projections of climate change. By combining o bservations with this emulator\, we attribute about 40% of uncertainty in projected climate sensitivity to processes leading to MLD biases. Ā Iā€™ll also show how an emulator (the energy balance modelā€“Kalman filter: EBM ā€“KF) can do many things we struggle to do with climate models. Ā It assi milates global surface temperature and ocean heat content to generate rapi d\, probabilistic projections and allows efficient exploration of policy t hresholds\, internal variability\, and the impact of external forcings lik e volcanic eruptions. A final emulator example is the ISEFlow ice sheet em ulator which allows projections of the ice sheet contributions to sea leve l rise. Ā This emulator has been trained against ice sheet resolving model s from the ISMIP6 project\, and it is changing our assessments of how sens itive ice sheets are to climate change. Ā I'll close with some of our plan s for emulators in Narragansett Bay--this ongoing work will allow us to do coastal modeling more efficiently and open up new evaluation techniques.< /p>\n

Together\, these new emulator toolsā€”optimized for interpretabili ty\, accuracy\, and speedā€”provide new ways to study the climate.Ā
