Short summary
We created a database of 19,540 thawing permafrost sites across Alaska, including both abrupt and non-abrupt thaw features and explored relationships with elevation, slope, and incoming solar radiation. We use the database to show that existing ground ice maps are too coarse to predict abrupt thaw risk. This database can enhance predictions of future thaw and guide planning and adaptation strategies.
