As impending threats of “climate change” and “ecological disaster” have loomed over international affairs this year, to the point that even the United Nations spearheaded a campaign and led a summit to discuss future changes that may amend for some of humanity’s grave mistakes, new research published this week in the journal Geophysical Research Letters looks to a place much colder than our metropolises for evidence of a rapidly shifting climate.
In Antarctica, much of life and history is swept away or covered completely by ice and snow. Even in the face of unending change, the surface appears timeless and constant, even though it sets the stage for some of the most tragic stories south of the equator.
The Antarctic ice is host to very little life, yet often researchers find that beneath the frozen surface we find remnants and a record of our past. Core ice samples not only reveal atmospheric concentrations of particular molecules in ancient skies, giving us a view of how the Earth’s climate has changed over eons even before the arrival of man, but also sometimes reveals a view of our own history on the icy sheet. This week, after more than a century since it was written and lost in a tragic expedition, the preserved journal of explorer George Murray Levick was found by researchers who recovered the photographic treasure from a casing made entirely of ice.
