2024 Fact Sheet: Natural Source Zone Depletion

After more than a decade of NSZD, this 2024 document is a great primer on the subject. Short , concise with five case studies of hard data using E-Flux Fossil Fuel Traps and other methods. A recommended read for new and seasoned readers interested in NSZD.
Read the full document.

Expressions of Biodegradation, Such as CO2,  Have Multiple Sources

Radiocarbon allows differentiating between CO2 from fossil fuel origin, from that of non-contaminant related sources.
