Human Contribution to Atmospheric CO2: How Human Emissions Are Restoring Vital Atmospheric CO2

View Now
Ferdinand Engelbeen, Renee Hannon, and David Burton December 2024 Since the beginning of the Industrial Revolution in the late 1700s, the average concentration of Earth’s atmospheric carbon dioxide (CO2) has increased by about 140 parts per million by volume (ppmv) to the current amount of about 420 ppmv. This is much higher than concentrations of… Continue Reading

Measurement of CO2 Concentrations Through Time

View Now
When recording historic levels of CO2 concentration, records from air bubbles in Antarctic ice cores are regarded as the gold standard for paleo-atmospheric global CO2 concentrations during past interglacial and glacial periods over the last 800,000 years.  Antarctic ice-core data are openly available from the National Centers for Environmental Information (NCEI) and have been studied… Continue Reading

CO2 Sample Spacing in Ice Cores

View Now
Renee Hannon – 24 June 2022 Introduction This post examines sample spacing for CO2 measurements in Antarctic ice cores during the past 800,000 years to better understand if gaps in sampling are too large to capture centennial fluctuations. The IPCC states: “Although ice core records present low-pass filtered time series due to gas diffusion and gradual… Continue Reading
