Jumping from rock to rock to rock over a creek formed off Austria's Jamtal glacier, scientist Andrea Fischer worries that precious scientific data will be irreversibly lost as the snow and ice melt faster than ever.
"I couldn't have imagined that it would ever melt as dramatically as this summer... Our 'archive' is melting away," says the glaciologist.
And based on the age of such material and the depth where it was found, scientists can infer when ice grew during colder periods, or when warmer conditions caused it to melt. "And we've got at least two months of summer left... where the glacier is entirely exposed to the sun," she warns. Fischer and her team have drilled on both the Jamtal and other nearby glaciers to extract data, taking out ice samples up to 14 meters deep.
