Abstract Text:
Anthropogenic carbon dioxide is the main driver of contemporary climate change. As such, its emissions, concentrations, and ensuing radiative forcing have been studied for decades, with high confidence in observations and simulations of many aspects of these quantities.
For CO2 radiative forcing in particular, detailed benchmark models simulate it in idealized cases with great accuracy. At the same time, however, coarse-resolution global climate models (GCMs) differ in their estimates of global CO2 forcing. Furthermore, questions linger regarding the spatial variations of CO2 forcing as well as its logarithmic scaling with CO2 concentration. In this talk we present recent progress in reduced-order modeling of CO2 forcing which answers these questions, while also illuminating a previously unidentified, major source of spread in GCM estimates of CO2 forcing.
