Extended Data Fig. 10: Temporal trends in the mean fire size, extreme fire size (95th fire size), and total burned area for all forests in Canada, USA, and Australia.
From: Forest fire size amplifies postfire land surface warming
The first, second and third rows correspond to Canada (a–c), USA (d–f), and Australia (g–i), respectively. The first, second and third columns present mean fire size, extreme fire size, and total burned area, respectively. Significance testing for temporal trends was carried out using the Mann-Kendall test (for Canada, n = 61; for USA n = 37; for Australia, n = 40), with all regressions being significant (p < 0.05). β values representing the temporal trends were determined using the Theil-Sen estimator. The numbers in brackets represent the 95th confidence intervals for the derived slopes. The relative growth in the mean (extreme) fire size was quantified as follows: 88% (65%) for Canada over 1960–2020, 448% (317%) for the USA over 1984–2020, and 124% (135%) for Australia over 1981–2020. Figure developed using the Python open-source tools.
