Critical Transtions in Ecology

In complex systems the degree of homogeneity (vs. Heterogeneity) and connectivity (vs. Modularity) determines whether or not there is a phase transition from one state to another. These are called critical transitions, and there are current efforts to understand both … Continue reading

Are We Entering an Era of Concatenated Global Crises?

An increase in the frequency and intensity of environmental crises associated with accelerating human-induced global change is of substantial concern to policy makers. The potential impacts, especially on the poor, are exacerbated in an increasingly connected world that enables the … Continue reading
