Antarctica’s oldest ice has arrived within the UK for evaluation which scientists hope will reveal extra about Earth’s local weather shifts.
The ice was retrieved from depths of as much as 2,800 metres at Little Dome C in East Antarctica as a part of a world effort to “unlock the deepest secrets and techniques of Antarctica’s ice”.
The ice cores – cylindrical tubes of historic ice – will probably be analysed on the British Antarctic Survey (BAS) in Cambridge, with the last word purpose of reconstructing as much as 1.5 million years of Earth’s climate historical past, considerably extending the present ice core file of 800,000 years.
The analysis can be anticipated to supply useful context for predicting future local weather change, Dr Liz Thomas, head of the ice cores workforce on the British Antarctic Survey, mentioned.
Over the subsequent few years, the samples will probably be analysed by totally different labs throughout Europe to realize understanding of Earth’s local weather evolution and greenhouse fuel concentrations.

Dr Thomas mentioned: “It is extremely thrilling to be a part of this worldwide effort to unlock the deepest secrets and techniques of Antarctica’s ice.
“The mission is pushed by a central scientific query: why did the planet’s local weather cycle shift roughly a million years in the past from a 41,000-year to a 100,000-year phasing of glacial-interglacial cycles?
“By extending the ice core file past this turning level, researchers hope to enhance predictions of how Earth’s local weather could reply to future greenhouse fuel will increase.”

The ice was extracted as a part of the Past EPICA – Oldest Ice mission, which is funded by the European Fee and brings collectively researchers from 10 European nations and 12 establishments.
“Our knowledge will yield the primary steady reconstructions of key environmental indicators-including atmospheric temperatures, wind patterns, sea ice extent, and marine productivity-spanning the previous 1.5 million years,” Dr Thomas mentioned.
“This unprecedented ice core dataset will present very important insights into the hyperlink between atmospheric CO₂ ranges and local weather throughout a beforehand uncharted interval in Earth’s historical past, providing useful context for predicting future local weather change.”
