Summary

Abstract: Reconstructions of ancient atmospheric CO2 variations help us better understand how the global carbon cycle and climate are linked. Here we compare CO2 variations on millennial time scales between 20,000 and 90,000 years with an Antarctic temperature proxy and records of abrupt climate change in the northern hemisphere. CO2 and Antarctic temperature are positively correlated over millennial-scale ...
