Extended Data Fig. 8: Distribution of 20-year trends in ΔSLP anomalies following all volcanic eruptions with SAOD equal to or greater than that of the 1991 Mount Pinatubo eruption (SAOD ≥ 0.1) during the 1200–2000 interval.

a, Full distribution of the magnitude of post-eruption 20-year trends in ΔSLP anomalies across 1900–2000 (from all individual reconstruction ensemble members, n = 4,800). Dark grey tails show the 2.5th and 97.5th percentiles. Red bar shows the mean magnitude of the 1992–2011 ΔSLP trend from instrumental data (following the 1991 eruption of Mount Pinatubo). b–d, As per a but only showing trends in reconstruction ensemble members trained on ΔSLP calculated from ERA-20C (ref. 27), ICOADS26 and HadSLP25, respectively. Red bar shows the magnitude of the 1992–2011 ΔSLP trend (from HadSLP and ICOADS) or the 1992–2010 ΔSLP trend (from ERA-20C) calculated from instrumental data. Volcanic eruption years taken from the ‘eVolv2k’ ice-core sulfate-based reconstruction of Common Era volcanic sulfate aerosol loading16,35. Note that differences between the panels arise mainly from differences between the three observational products.
