Ice cores and mammoth extinction
Article Abstract:
The stability of the Holocene interglacial climate change may answer the questions about why mammoths were made extinct by the Holocene interglacial and not previous interglacials. Based on some ice core data, significant climate variation occurred during earlier interglacials which may have allowed pockets of the megafaunal species required by tundra-steppe grazers to survive despite the climate changes. However, the changes at the Pleistocene/Holocene boundary were stable, creating climax vegetation zones with less climatic variability.

Contrasting atmospheric and climate dynamics of the last-glacial and Holocene periods
Article Abstract:
A study was conducted on the atmosphere and climate of the last-glacial and Holocene periods. Ice-core data from Greenland with a temporal resolution ranging from seasons in the present to approximately 10 yr at 91 kyr before present was analyzed. A 20-year low-pass was applied to discard artificial trends caused by poorer resolution in the record bottom. Results provided direct proof that atmospheric circulation during the last glaciation was more turbulent than at present.

Survival of the Irish elk into the Holocene: giant deer on the Isle of Man around 9,000 years ago may have been the last of the line
Article Abstract:
A new study uses radiocarbon dating to show that the giant deer Megaloceros giganteus was not extinct by the end of the Late Glacial age, but still existed around the basin of the northern Irish Sea in the early Holocene, some 1,400 years after its assumed demise.
