Asexpected, when temperatureincreased, carbon dioxide followed, but at both Sipleand Byrd the time lagwas around 200 years - much shorterthanprevious studies found.
The Siple Dome, an ice dome roughly 100 km long and 100 km wide, about 100 km east of the Siple Coast of Antartica, also reflects effects of the Little Ice Age synchronously with the GISP2 record, as do sediment cores from the Bransfield Basin of the Antarctic Peninsula.
