Complexity in the air

This story covers the history of the popular reception of complexity and chaos, and how, in the process of translation from natural science to popular culture, ideas like complex systems and the butterfly effect have been used to buttress both deeply reactionary political projects and left-wing ones. This essay asks: Does complexity have any inherent politics? If it does, what are the implications for markets, planning, and collective environmental action?

A random media appearance

Blueprint from the Australian Broadcasting Corporation (radio)

19 February 2021 | Listen here

In this radio interview, my co-author Troy Vettese and I spoke with Blueprint's Jonathan Green about how land use change might help us make sense of recent global fire crises from California to Siberia, Brazil to Australia.

All the cool kids are using CHEEREIO!

CHEEREIO is a tool that uses observations of pollutants in the atmosphere, measured from satellites or surface stations, to correct supercomputer models that simulate the Earth. Powerful use cases for CHEEREIO include tracking pollution back to its source, even if there are no local observations on the ground, and monitoring greenhouse gas emissions in near-real-time. Read more on my projects page or the offical CHEEREIO site.
