  1. Trends in the temperature of cold events (°C/30 events) from ERA5 reanalysis using fixed and moving threshold and across different time periods. The regions used are the same as in Cohen et al.2: Central and Eastern United States (CEUS; 30° to 50°N, 75° to 110°W), Southern Siberia and Northern China (SSNC; 40° to 60°N, 80° to 120° E), Northern Europe (NEUR; 50° to 65°N, 0° to 45° E) and Southern Europe (SEUR;35° to 50°N, 0° to 45°E). Bold values indicate statistical significance at the p = 0.05 level. Following Cohen et al.2 we use a python scipy stats to calculate statistical significance.
