Figure S2: Change in the joint probability that the annual mean count of two or more event categories exceed their respective thresholds between the period 1961—1988 and 1989—2016. These values lie in the region of – 1.0 to 1.0 and convey information on the change in the risk of (a) two, (b) three or (c) four extreme events occurring within the same year. Significant change was inferred for probabilities above 0.05 or below –0.05.
