Goehring said he was surprised by the evidence of exposure revealed by the isotopes. 12. Climate Change Earth. In addition to the global implications of increasing climate warming and instability, the local economy is at risk of losing business income from glacier tourists who have flocked to the area since 1870 to walk through "a long and winding ice grotto with glistening blue walls and a leaky ceiling".

He said the findings show that even though the climate shifts were relatively mild during the Holocene, “we find that the glaciers really reacted strongly … telling us they are very, very sensitive to even very small [changes]. Historic Front Variations of the Rhone Glacier: Simulation with an Ice Flow Model. Glacial ice can range in age from several hundred to several hundreds of thousands years, making it valuable for climate research. The findings “may potentially open up our work to application globally at many different glaciers, to begin to piece together a global picture of Holocene glacier advance and retreat,” said lead investigator Brent Goehring, a former PhD student at Lamont and now a post-doctoral researcher at Pennsylvania State University.

Residents of the village of Gletsch, down the valley from the glacier, have kept track of the ice since 1602. The Swiss Alps record contrasts with the record of glacial movements in the Southern Alps of New Zealand, where the glaciers appear to have been larger than at present for most of the Holocene.
