Attribution - Episode 1 - Unraveling Historical Climate Variability through Detection-Attribution Simulations

The climate variability simulated in global atmosphere ocean general circulation models (AOGCMs) can be decomposed into a forced and an internal component. The forced component arises from external forcings, including increased atmospheric greenhouse gases, changes in aerosol concentrations, and variations in solar incoming radiation. Detection-attribution simulations enable an exploration of the role of each external forcing. In this seminar, I will discuss recent findings from AOGCMs, focusing on the North Atlantic region. The presentation will highlight the relative importance of individual external forcings and present the latest estimates of observed changes attributed to each factor. Additionally, I will introduce results obtained through a novel statistical framework that accounts for potential non-additivities.
