The article cites a report within the issue regarding climatology research by J. Schmitt and colleagues that provides carbon isotopic data that may help explain changes in atmospheric greenhouse gas carbon dioxide (CO2) beginning 24 thousands years ago. Topics include an explanation of changes in CO2 concentrations during ice age cycles, the challenges of obtaining consistent patterns in CO2 concentrations, such as a lack of detailed and precise ice core isotopic measurements, and how Schmitt and colleagues overcame these challenges to produce what is reportedly the best record thus far of the glacial to interglacial variations in stable carbon isotopes of CO2.
