Carbon dioxide did not cause the end of the last ice age, a new study in Science suggests, contrary to past inferences from ice core records.
“There has been this continual reference to the correspondence between CO2 and climate change
as reflected in ice core records as justification for the role of CO2
in climate change,” said USC geologist Lowell Stott, lead author of the
study, slated for advance online publication Sept. 27 in Science Express.
“You can no longer argue that CO2 alone caused the end of the ice ages.”
Deep-sea temperatures warmed about 1,300 years before the tropical
surface ocean and well before the rise in atmospheric CO2, the study
found. The finding suggests the rise in greenhouse gas was likely a
result of warming and may have accelerated the meltdown – but was not
its main cause.
The study does not question the fact that CO2 plays a key role in climate...
