Resource: Scenarios Network for Alaska + Arctic Planning (SNAP) community charts explore temperature and precipitation projections for communities across Alaska and Canada. Due to variability among climate models and among years in a natural climate system, the graph is useful for examining trends over time, rather than for precisely predicting monthly or yearly values for any given community. Results are averaged across decades to lessen the influence of normal year-to-year climate variability on projected values. Averaging also tends to make overall projection trends clearer. According to the SNAP Community Chart, average February temperatures in Nulato are historically below zero degrees Fahrenheit, but have been gradually warming. As described by Nulato Tribal Council, the temperatures are unseasonably warm.
