Highest CO2 levels in 650 Ka
A new ice core drilled in Eastern Antarctica by European scientists offers an unprecedented look at CO2 levels during the last 650,000 years. According to new studies based on this ice core, CO2 levels are 27% higher than at any point during the last 650,000 years.
Today’s rising CO2 concentrations are 27 percent higher than at the highest level seen over the 650,000-year time scale, according to the study, which appears in the weekly US journal Science.
The Dome C core, extracted by the 10-country European Project for Ice Coring in Antarctica (EPICA), outstrips by 210,000 years the previous record-holder, drilled at an Antarctic site called Vostok.
