This High: 15 Million Years Ago, Scientists Report ScienceDaily
(Oct. 9, 2009) — You would have to go back at least 15 million
years to find carbon dioxide levels on Earth as high as they are
today, a UCLA scientist and colleagues report Oct. 8 in the
online edition of the journal Science "The last time carbon
