People and Sulfur: The Forgotten Element Cycle

The carbon cycle has taken centre stage as a global element cycle in the run-up to the Paris climate conference and beyond. Even the nitrogen and phosphorus cycles get plenty of attention in their role as critical elements for food produc­tion, as well as pollutants that can eutrophy freshwater systems and the coas­tal zone. But in many ways, the global sulfur cycle is just as important.

It was at the centre of the acid rain problem that afflicted Europe and eastern North America a few decades ago. For many years, sul­fur compounds have been central to the role of aerosols in local and regional air pollution, most notably as a feature that threatens the sta­bility of South Asian monsoon sys­tem and that drives health impacts through urban air pollution.

But the sulfur cycle is also crucial in the functioning of terrestrial and marine ecosystems. In fact, one of the key feed-back mechanisms that operates in the global climate sys­tem, involving marine microorga­nisms and clouds, could be coupled to the sulfur cycle.

This seminar explores the global sulfur cycle and its complex relationship with people with 2015 Volvo Environment Prize laureate Professor Henning Rodhe and colleagues.
