Fig. 4From: Evolution of threats in the global risk networkAsymptotic mean-field steady state frequencies of selected risks being active are shown for the 2017 risk network. Each frequency value is averaged over 1000 runs. For time denoted on the x-axis as “inf”, the frequencies are calculated by Eq. 6. The environmental group of risks is most frequently active in this year, but the general level of risk activities is quite low. a Economic b Environmental c Geopolitical d Societal e TechnologicalBack to article page
