Extended Data Fig. 1: Drivers of no escape events.
(a) Correlation between the inter-annual variability in the number of no escape events and the occurrence of surface heatwaves. (b) Average correlation in mixed and stratifying lakes. (c) Relationship between the average number of no escape events and lake surface heatwaves. (d) For stratifying lakes, we show the relationship between the average number of no escape events, the number of surface heatwave days, and the proportion of stratified ice-free days. (e) Changes in the number of no escape events between 1980-1999 and 2000-2022. (f) Relationship between the change in the number of no escape events and the number of surface heatwave days. (g) For stratifying lakes, we show the relationship between the change in the number of no escape events, the number of surface heatwave days, and the proportion of stratified ice-free days. In each box plot (n = 16,455), the central mark indicates the median, and the bottom and top edges of the boxes indicate the 25th and 75th percentiles, respectively. The whiskers extend to the most extreme data points not considered outliers. Basemap in a made with Natural Earth.
