Greenland Ice CO2 – Chemical Reactions or Natural Variability?

Guest Post By: Renee Hannon IntroductionThis post examines whether CO2 measurements in Greenland ice cores demonstrate natural variability as an alternative hypothesis to in-situ chemical reactions. Twenty years ago, scientists theorized Greenland ice core CO2 data were unreliable because CO2 trapped in air bubbles had potentially been altered by in-situ chemical reactions. This theory was…
