The ice in glaciers has hardened into an identifiable pattern,with each year leaving a distinct layer in an ice core.
The dating of these carvings also matches an ice core taken from Greenland, which pinpoints the Younger Dryas period as beginning around 10,890 BCE.
The ancient temperature drop, called the Younger Dryas, has been well documented in the geologic record,including soil and ice core samples.
In a breakthrough a decade ago,European scientists extracted an ice core nearly 2 miles long that revealed 800,000 years of climate history.
While ice core records from the tropics are available to researchers, interpreting information about past climate from them can be complex.
There appears to be folk wisdom that“the typical interglacial period lasts~12,000 years” butthis is hard to substantiate from the evidence of ice core records.

Scientists hope that the ice core will unlock the story of Earth's shifting climate, as the composition of Earth's atmosphere is preserved in bubbles in the ice. .
But finding an ice core going back further would allow scientists to examine a change in the earth's climate cycles believed to have occurred 900,000 to 1.2 million years ago.
The Greenland ice core data display an abrupt climate change around this time, but there is no consensus that the eruption directly generated the 1,000-year cold period seen in Greenland or triggered the last glaciation.
Our work with ice cores drilled in the Antarctic Ice Sheet have shown, for example,that wind conditions have been similar in the past. But the ice core data also suggest a subtle long-term trend in the winds. This new work corroborates that evidence and, furthermore, explains why that trend has occurred.”- Climate News Network.
