Preliminary Screening of Features, Events, and Processes for an Arctic-Focused Climate Intervention Performance Assessment

Summary

This Sandia National Laboratories report, "Preliminary Screening of Features, Events, and Processes for an Arctic-Focused Climate Intervention Performance Assessment," addresses the challenge of rapid Arctic warming, which is occurring at more than twice the global average and accelerating ice and permafrost melt. It adapts the Performance Assessment (PA) methodology, originally used for nuclear waste disposal over thousands to millions of years, to evaluate Arctic Climate Intervention strategies. The preliminary screening process identified a total of 188 independent features, events, and processes (FEPs) from an initial 227, comprising 103 features, 11 events, and 74 processes. The analysis focused on describing 94 Atmospheric FEPs, with the remaining 40 Oceanic, 55 Land, and 23 Other FEPs awaiting detailed screening. This work lays the groundwork for a robust assessment framework to inform decision-making on climate intervention impacts.
