Title: CO2 leads the way - New study complements ongoing research on WAIS Divide ice core

A new study, funded by the National Science Foundation and published in the journal Nature this month, suggests that rises in global temperature follow increases in atmospheric carbon dioxide.

The researchers constructed a record of global surface temperature from 80 temperature reconstructions spanning more than 20,000 years since just before the end of the last ice age, which scientists refer to as a glacial period. The reconstruction found that average temperatures around the Earth correlated with – and generally lagged behind – rising levels of CO2.
