[Geology2] Extreme Global Warming in the Ancient Past

Extreme Global Warming in the Ancient Past
ScienceDaily [USA], Nov. 11, 2010

Variations in atmosphere carbon dioxide around 40 million years ago were
tightly coupled to changes in global temperature, according to new
findings published in the journal Science. The study was led by
scientists at Utrecht University, working with colleagues at the NIOZ
Royal Netherlands Institute for Sea Research and the University of
Southampton. "Understanding the relationship between the Earth's climate
and atmospheric carbon dioxide in the geological past can provide
insight into the extent of future global warming expected to result from
carbon dioxide emission caused by the activities of humans," said Dr
Steven Bohaty of the University of Southampton's School of Ocean and
Earth Science (SOES) based at the National Oceanography Centre in
Southampton.
