Current carbon dioxide levels also prevailed 15 mn years ago
"We are able, for the first time, to accurately reproduce the ice-core record for the last 800,000 years - the record of atmospheric carbon dioxide based on measurements of carbon dioxide in gas bubbles in ice," Tripathi said. "This suggests that the technique we are using is valid."
"We report evidence for a very close coupling between carbon dioxide levels and climate. When there is evidence for the growth of a large ice sheet on Antarctica or on Greenland or the growth of sea ice in the
The study is slated for publication in the journal Science.
