Extended Data Fig. 4: Global trends of GLOF volume V0 and peak discharge Qp with time t obtained by hierarchical quantile regression.
From: Less extreme and earlier outbursts of ice-dammed lakes since 1900
a, Pooled global trends in median and extreme V0 for the period 1900–2021. b, Pooled global trends in median and extreme V0 for the period 1990–2021. c, Posterior pooled trends in V0 for the 50th and 90th percentiles for both periods. d, Pooled global trends in median and extreme Qp for the period 1900–2021. e, Pooled global trends in median and extreme Qp for the period 1990–2021. f, Posterior pooled trends in Qp for the 50th and 90th percentiles for both periods. In a, b, d, and e, colours distinguish between the median (blue) and 90th (orange) percentile of reported V0 and Qp, including the posterior 95% HDI (shades). In c and f, lines are the posterior 95% HDI and dots are the median of the global mean regression trends, grouped by the period 1900–2021 (dark green) and 1990–2021 (light green). Distributions overlapping with zero (dashed black line) indicate the lack of a credible trend in V0 and Qp. In c and f, πpost <0 denotes a posterior mass smaller than zero.
