Biosignatures & Paleobiology: February 2022

The presence of chlorofluorocarbons (CFCs) in Earth's atmosphere is a direct result of technology. Ozone-depleting CFCs have been banned by most countries, but some CFCs have persistent in elevated concentrations due to their long stratospheric lifetimes.

We present a new approach to exoplanet characterisation using techniques from complexity science, with potential applications to biosignature detection.
